Mostly good information; however, there are important details missing. More important than the laser power is the per-pulse energy (PPE). PPE tells you more about the laser than just how much energy is in each pulse. Generally speaking, a laser with a PPE of under 1mJ indicates inferior fiber; the pulse energy is managed to reduce the liklihood of fiber damage caused by the laser being absorbed by fiber impurities. How do you know what the PPE of the laser is if it's not listed in the specification sheet? Divide the maximum power by the lowest Pulse Repetition Frequency (PRF) for a Q-switched laser (optimum pulse repetition frequency (PRFo) for MOPA), and you get the approximate PPE, i.e., 20W / 20,000 = 0.001J = 1mJ. I would not buy a fiber laser that has a PPE under 1mJ. Another advantage MOPA has over a Q-switched fiber laser is the ability to go below the optimized pulse repetition frequency (PRFo). PRFo is the frequency where both pulse energy and power are at their maximum. Below PRFo, power is reduced approximately linearily, and pulse energy is usually capped at the maximum (fun fact, in diode-pumped open-air lasers, pulse energy increases below PRFo). Since we consider power to be "heat", we're effectively engraving with a lower heat affected zone (HAZ), which means better cuts--typically we want high PPE to engrave, and power (heat) to mark/anneal. Combine this with the ability to modify the pulse width, or the time each pulse interacts with the material, and we have complete control over the application. Why can't you anneal with a Raycus laser? The IPG laser systems Control Laser Corporation (CLC) was selling when IPG came out with their 20-Watt laser came with a Linos 254mm Focal Length (FL) lens, having a 7-inch field. These are 1mJ lasers, and are very capable of annealing with the correct parameters. I would argue that the Raycus systems likely have a cheap Opex lens, and this, combined with the low PPE is why these lasers have difficulties annealing. The Opex lens resolving power is crap; there is no discernable airy disc with these lenses; the laser is diffused too much, causing energy density to suffer. A Linos or Rofin-Sinar lens, having that large 120mm output lens, have wonderful resolving power, and this is why the IPG 20Watt laser, having a maximum frequency of 40kHz, can anneal all day long without problems. Yes, the Linos lens is about $1,600 more than the ~$50 Opex lens, but when you consider that you need to add more power with the Opex lens to get the same effect (energy density) as the Linos lens, it's cheaper to buy an expensive lens than to buy a laser with more power. Also important is the size of the laser beam going into the focus lens, as this is one of the parameters to the spot size algorithm. If the beam is small going into the lens, the spot will be large, i.e., low energy density. However, if the beam is large going into the focus lens, the spot will be small, high energy density. So, it's important to consider the complete system when talking about capabilities and applications, and comparing between systems. Stick a Linos lens on that Raycus, expand the beam to 8mm, and see what happens! Finally, I want to clarify that IPG is originally a Russian company, that moved the headquarters to Massachusetts to have a better political environment to operate in. Yes, there are factories in Germany, and still in Russia, and yes, those Chinese systems that claim to have IPG lasers in them are really IPG lasers (manufactured in Russia). Most general purpose fiber lasers from IPG are manufactured in Germany, and I think that's what you meant to say; i.e., the German IPG fiber is the holy grail of q-switched fiber lasers. (For MOPA, SPI Lasers, now part of Trumpf, is the equivalent). -Laser-Lance (AKA Vasily Basov, former employee of Control Laser Corporation, part of Hans Laser, China)
Lance, So after everything you said, is there a laser you would reccomend instead? Is there one that is strong enought o engrave in metal and softer materials like wood? And any of them have US support? Thanks so much in advance!
You're not going to find a laser that specializes in engraving wood and metal. CO2 lasers are used to engrave organics like wood acrylic glass and leather, fiber lasers are used to engrave inorganics like steel aluminum brass and copper.
I'm about to purchase one and they said laser source is Max and JPT and laser frequency is 20 - 80 kHz with cost 1500$ I have no idea but now I realized that I have to search for another, thank you for saving our time and sharing those details,
This is a great video and I've referred to it several times. Here we are in Jan of 2022, and I think the pricing is changing a LOT. A 100W Raycus Fiber Laser is now about the same price as a 50W MOPA. I know I'm going to want color if I don't have it, but a faster laser running 2x the power would also be nice. I'm in analysis paralysis!
It can definitely be hard too choose. Just know the MOPA colors are extremely inconsistent, difficult to master, and no one will be able to help you because variables like the temperature of the room can effect the outcome. Very steep learning curve.
I didn't have this information when i bought my machine but it looks like the research I did payed off. 100 watt JPT MOPA split from MORN. It works well from what I know how to do and this channel is helping a bunch!! Now I just need to do the conversion from the library you gave us for my machine and figure out the Q plus width setting. Thanks again!!!
Great breakdown. I wish This video existed a couple years ago when I bought my 30w JPT MOPA. I could have saved a lot of money sticking with a standard, but I was sold on the colors before I knew the beautiful photos shown of color where taken at very specific viewing angles.
I know it's the end of 2022 now, but I just purchased a brand new 30W Raycus Fiber Laser with a 200x200mm lense for $1,600 and free shipping from the USA! The seller was asking $1,800 obo on eBay for it because the Z Axis focus knob had gotten broken off during handling but they assumed the rest of the machine functions as intended and nothing else was damaged, so I offered $1,600 and they accept and they are even going to ship out a new focus knob for it. Honestly I'm not even worried about the knob as it looks like I'll be able to 3D print a knob for it no problem. And at the price I paid, that easily leaves me plenty of money to pick up a rotary and a smaller lens or two.
Having never used or seen a fiber laser in action only on TH-cam I have decide to purchase one to hopefully enhance the Fountain pens I make, so I have taken your advice and ordered a Cloudray 50w JPT as you recommend them highly, at the age of 70 I think I will be seeking advice in abundance, Thank You.
Thanks for all you did .. I am so happy to see all your videos, you making it usually. its very usful and teaching others. its so genius and helpfull. Wish i know most of this infomation befoer buying my fiber laser. waiting for you to buy the UV laser and start your journy of expermets .. good luck Bro.
We're getting really close on the patreon! Hopefully we will be able to pick the UV up soon and we can get started down that road as well. Thanks for your unwavering support Daifallah!
All i need to know is what would be good for clean detailed scroll work on SS ? Yes I’m talking about firearms. My thinking is if I purchase a machine that can do that without issue , it can do a lot more I may need- various text, knotwork,simple images simply . I’m assuming there’s been improvements since 2021 also.
My friend, do you use an outlet plug of 220 volts or 120 volts because in China they use 220V and the videos they show us are of a fibre laser with a 220 volt power? Only 120V is used in the United States and Canada. Unless you have a 220 to 250V special outlet installed. Also if a 120V 50W fiber laser was to vs a 220V 50W fiber laser what would be the difference in terms of engraving on jewellery metal and quality of products etc....
We use 120v. There's no difference in terms of the actual engraving. The 120v systems pull more current to meet the wattage spec but it doesn't effect the operation of the laser or what they're capable of, since everything is transformed by PSU's to DC inside the machine anyway.
So I have a limited budget. I can afford either a 50w JPT or a 30W JPT mopa. The color aspect is very cool, but the 50 is faster and can deeper engrave, right? Any advice? Thanks.
Maybe or probably it's a dumb question, but, I want to know as much as possible. I saw how the fiber laser machines how can they work, and, of course, the galvanometer is the optimal way to mark fast or engrave using the fiber laser beam. But, what happen if I want to mark multiple drawings over a stainless steel sheet, 2.44m * 1.20m (for example), the station's space is not enough to be possible to work these dimensions. If I want to build a cnc machine, can I just buy the fiber laser source and "power on" / "power off" when it's required according to my motion requirements ?. I don't know if it's mandatory to buy and use the control board included with the portable or workstation versions to be possible for me to control the fiber laser according to my needs (enable/disable the power beam required), and I don't know if I can ignore the presence of the galvo and use only the fiber source and execute some testings (assuming I can control it without issues). I don't know if with some changes, "S" parameters inside gcode can be changed and assuming there is some kind of bridge between the motion controller and the fiber laser (with or without it's original controller) it could be possible to "invoke" the required power beam. ¿ "Pros" and "cons" about this ?. I'll appreciate any comment that you can give me... I'm just trying to figure out if it can be possible. Thanks in advance !
It's possible but reflecting 1064 in a gantry system is kind of a rare special use case. Epilog does it best with their Epilog Fusion machines which come in very large bed sizes. I'd look into a system like that if you need to work on spaces that large.
I think Raycus product is mostly at 1000w level, with wave length at 1080nm, which is 285M Hz frequency. User can easy blind himself even with eyes closed, even only facing the light spot on the wall. It is not for hobbyist.
Hi Alex, FYI, I purchased a Mactron JPT 50w laser. I checked the model number of the laser source: YDFLP-E-50-LP-L-R. I did a search for that model number and it is listed as a MOPA pulse fiber laser. This appears to be the source when ordering the JPT. Thought you could use that bit of info with your recommendations. The case appears to be the same build quality as your new CO2 galvo unit. Thumbs up for Mactron for constantly improving their product line.
Yep all JPT are technically mopa on some crazy science level I don't understand. The LP series is what we would consider q-switch though. Solid standard unit. Glad you got the updated casing. It really is nice and shiny huh? Can't wait to oogle at it some more tomorrow!
That's interesting and I must investigate further as my "non-MOPA" JPT 50 will produce various colours in steel. Hearing that this feature is unique to mopa makes me wonder. (pleasantly).
What do you suggest? I want one of hobbies small stuff but also need to engrave handguns and rifle parts. And glass. Maybe cut wood if anything but over all what’s the best one in your thought?
Hello, can you speak to units for "laser cleaning" technology? I have a specialized application for removing mineral deposits from ceramic and/or cementeous surfaces without etching the substrate. The German IPG sounds intriguing as the ability to choose color would be valuable not to mention integrity of beam. Manufacturer(s) you'd suggest?
Happy to help! I also highly recommend our podcast episode on 5 tips you need to know before importing a laser! Really good info in there for you too! Available on all podcast sites and the video version is on our youtube channel.
@@LaserEverything Thanks for the response. I prefer to buy locally in India so I can avoid warranty issues. Prices are similar but I want to go shopping armed with the knowledge about subtleties like MOPA and laser sources you explained. Tons of companies in India too trying to pass of some cheap chinese laser as "IPG".
What I’m looking is a laser that can cut really thin metal for watch parts with precision! Could recommend or do a video about something like that? I don’t need to thick metal!
First, I was ecstatic to find this video!!! I'm in the process of starting a business that will heavily depend on laser engraving. I've been doing my homework on various fiber lasers in general, it's great to see a knowledgeable channel that isn't manufacturer sponsored. I did already know that I need a MOPA Fiber laser. That said, your breakdown really cleared up a couple of things for me, especially in relation to pulse frequency. Quick question, are you familiar with LaserStar? If so, what do you think of their products & services? At any rate...back to binging on your channel!
Not familiar with LaserStar but before you commit to a brand DONT SKIP ON THE PODCAST - go watch/listen to every episode of it like, right now. Most important info before buying a laser can be found there. Lots of perspectives, experiences etc we get really specific. Highly recommend it!
@@LaserEverything Will do! I have one other question for you that I can't get a solid answer on. I know MOPA lasers can engrave color on stainless steel, titanium, and a few other metals for sure, but can it do it on aluminium as well or only shades of grey?
I purchased a 50w raycus qb fiber laser marking machine 8 month ago and 2 days ago it just stopped working so i took it to the seller and he said that the laser source is burnt and there is no warranty for that, i never used it for more than 6 hours a day and never used power more than 95% ,please tell me how did it got burnt and what's the meaning of that. I am helpless right now😔😔 it's only been 8 month. Is there a way to repair that laser? Please reply
That response doesn't really make any sense to me Mohd and the source should absolutely be covered under the warranty so that's a scam. Please join either our discord or facebook group (there's links in the video description) and make a post so we can take a closer look at what might be going on.
I don’t have a fiber laser so I cannot check this but I had a thought that since borax is sodium-based (a metal ) Wood or birch plywood treated with borax might react to a fiber laser engraving. Could somebody, back thank you
I'll check it out and see if it helps. If it does it's a work around, still won't provide anything near the results you're going to get with a laser designed for organics.
I have one question I would like to understand, can this fiber laser engrave on acrylic or clear painted acrylic or white painted acrylic to obtain that backlight?
Could you help me with getting the best laser for my application. I make silver hand pours and am looking to engrave portraits on the bars and don't have a clue what to get.
For silver you really want to be looking at 50w+ as it will reflect a ton of the 1064nm laser light. All of our reviewed recommended brands can be found at www.lasereverything.net/buyingguide/ Highly recommend checking it out!
For precious metals you really want to be looking at 50w+ as they will reflect a ton of the 1064nm laser light. All of our reviewed recommended brands can be found at www.lasereverything.net/buyingguide/ Highly recommend checking it out! For cutting 1mm sheet I'd really be looking at 50w + options, even then these lasers aren't really designed for cutting so expect it to be a long wait - will take patience.
Firearms are actually pretty easy to work with so you should be able to use just about any system. It's more about the size of the parts you want to mark. The larger you want to do in one shot the more power you'll have to have to drive the larger lenses.
Everything Trotec produces is proprietary. While they may use some common laser sources, their controllers and supporting hardware are required in order to take advantage of their software so unfortunately the answer is unlikely.
Hello. I can confirm that with a 30w Raycus you can anneal steel with the right settings, deep back and fast. Actually, i have hot Mopa 60w and the black isn't deep black as than with raycus
I have a nice price for a JPT MOPA 60w engraving machine. If I am correct the MOPA can do anything a Fiber laser can do, just that it also offers some additional settings like the pulse width? I am mainly interested in black engravings on steel. I just want to be sure that i am not buying something that will not be so powerful for black as lets say a 50w raycust or an ordinary jpt laser? Thanks. also, ofcourse i want to experiment with colors on steel in the future.
@@LaserEverything thanks. i am considering 60w jpt vs 80w jpt - what can 80w do what 60w cannot? are there any disadvantages of more power? (finesse,beam width or something like this?)
This is a great. Thank you so much. Any idea what I need for engraving polyurethane thermoplastic material. This are for for medical and dental applications.
The Mactron is always my recommendation. JPT for high frequency and 50w is good for defeating precious metal reflections. Link in the description or check out the laser page on my website for more info www.lasereverything.net/lasers
The only laser I'd check out as of right now would be one of the EM-Smart units. Get as much wattage as you can afford. That's as small as I'd go. Jewelry can be particularly reflective and can require very focused power to ablate sometimes. Here's a link to our review of the Basic 2R: th-cam.com/video/er8vi_uCcgY/w-d-xo.html
I Just ordered a Cloudray fiber laser marker with a 30W JPT LP-series laser source, and are a bit confused. Is the JPT LP-series a MOPA laser? If it is a MOPA laser, it seem to me that JPT only make MOPA lasers. What is the different then between the LP series and the M7 series?
While the LP units use MOPA technology to manage their frequencies, the pulse duration is locked at 200ns. With an M7 that pulse duration is unlocked and a new variable is able to be changed. LP units are not "true" MOPA lasers in practice.
I didn't measure but there was quite a bit of loss. You would want to use something like a fume extractor to capture the gold dust lost in the process.
Most fiber lasers these days come with rotary tools to do round items. Fiber lasers can mark any metal. You can find our updated list of recommended machines at www.lasereverything.net/buyingguide :D
Yeah you could theoretically turn the galvo head upside down on your unit. Doesn't really matter which direction the galvo head is pointing, the light doesn't care what direction it's shooting.
My friend. I need Your help please. I bought a laser Machine called Aufero LU-2, but i need engraving in Silver but i can not use it. Its difficult for me, i AM beginner in this. I have tried in wood ando it's ok, but i need only JEWELRY silver
Great video and a great channel name. Thanks for putting this together as this will be the next component to my shop as the xcarve and my laser can only do so much.
i have been looking for a laser engrave machine for my jewelry business . in which i mostly be using 5 to 6 inches area and mostly sterling silver and stainless steel will be my material . i might like to cut out 1mm sheet of these metals too. can you give me a advice which will be good for me in both money saving and in long term jewelry business ?

You shouldn't unless it's really really hot. Like 90+ F I would consider it. Make sure the vents are clear and the fans on your system are all working but it should be okay.
Hello. Would you have this information that you said in the video in text format? Because my English is very weak and TH-cam insists that you are speaking in Vietnamese, then the automatic translation is crazy and nothing is understood.
Hey Alex, I really appreciate all of this information. Truly and amazing wealth of knowledge. I have been following you for some time, but never purchased. I recently (impulsively) purchased a Laser Pecker 2. It was a good little machine but can’t even get close to what I want to do. To keep story short I returned it and am looking at at fiber laser with atleast a 30w raycus. What’s your thoughts on Omtech and Monport? They seem pretty reasonable on price and I’m really trying to stay on the lower end of budget. Thank you in advance!
I haven't had my hands on either of those lasers unfortunately. We do have a buying guide on our website with machines we have in our shop and can recommend.
This isn't a cutting machine and it shouldn't be used that way. It can cut very thin very soft metals only - otherwise you're gonna have a really hard time. Use these machines for marking and engraving only.
Gold is really reflective. I'd recommend at least a 30w. The 20w will do it but it will struggle. I always recommend the Mactrons which are linked in the description!
HELP, What do I need for Only Engraving Urns 90% Brass? I was quoted over $18,000 for Ap: in addition can I use Gerber Omega design software or do I need to spend more money on software????
Brass urns can be engraved with any standard fiber laser. Getting around the curves will be helped by getting a higher wattage machine like a 50 or 60w with a large lens size like 200mm - 300mm. I would put your budget at $6,000 - $10,000

My working area is ranging from 50mm L X 50mm W up to 300mm L X 300mm W on the minimum of a 0.2mm thick copper sheet. Can I engrave using only a 50W lens on various sheets without cutting through or do I have to change lens accordingly?

get one lens with your mactron fiber, doesn't really matter which, then get the rest from cloudray I recommend starting with a 110 on the 30w that's my daily driver the rest you can get from the links on the buying guide www.lasereverything.net/buyingguide for a Mactron unit you want the "Standard" lenses not the OPEX
I have a 50 watt JPT source fibre laser. Im having trouble with cutting sterling silver with brown fleck markings (like burn marks) across the surface which dont diasapear after sanding, pickling, polishing etc. Has anyone else experienced this?
Sounds like spash damage. I'd reduce your power, increase your speed a bit and increase the diameter of your wobble to assist in cutting. Low and slow yields cleaner cuts - even though they take longer.
Hi guys I hope you can help. I have sliced an stl file for my 60 watt 2.5d MOPA laser and started to run the file. Everything was going well until it hit layer 94 then it will not go any further - can you help and how to fix. I am using Ezcad3
Check out the links in the description to or Facebook Group or Discord Server. I am sure someone in the community would be willing to help out. I don't currently own a machine that can use sliced STLs so I won't be very helpful but we have lots of community members that do.
Depends on what you plan to use it for honestly. If you need raw power I'd go with the Raycus. If you want more fidelity I'd go with the JPT. Either will be great though. If I just had to pick right now without more info I'd probably go with the JPT.
i have a portable 50w one with a range from 50 to 100khz. only problem is i don't get what the frequency does and don't see any difference while marking under any frequency. anyone care to help?
The higher the frequency the more pulses the laser is doing. The shorter the pulse the less power can fit into each pulse, but the more of them there are. It essentially "softens" the blow each time the laser pulses. Higher frequencies tend to heat metals, lower frequencies tend to ablate them.
@@LaserEverything thank you very much, helpful! Also, what do the settings under the speed and freq mean? I see everyone has them 100/300/100/100 but just mine are -180/200/50/50
If you buy a Cloudray laser from Amazon or from cloudray directly which is cheaper. I am looking at a 50watt JPT MOPA laser at both from amazon (Cloudray) and cloudray's site. I asked them if there are any extra fees that needed to be paid over the price shown, they said there would be taxes to pay but would not give me any kind of idea how much those are. I assume if you buy one from amazon all fees including shipping are included. Any help on this would be appreciated, i joined your 8 dollars a month program yesterday, thank you for any guidance.
Yes that laser from their website would almost guaranteed cost you duties which can be up to 30% of the price of the laser depending on where you live. The price difference is substantial because the duties are already paid on the Amazon machines because they already had to be imported likely stored in a local warehouse. At any rate I really don't recommend the cloudray too much anymore. A lot of members of complained to me over the last six to eight months about their quality and customer support. I'd check out some of our other recommendations instead. There's a link to the buying guide in the description.
I bought a seaman CNC system which was supposed to be 100watts. Just tested power and looks like they put a 50watt RAYCUS and only makes 46 watts with or without lens and directly from coupler. Got scammed
That sucks dude I'm so sorry to hear that. I've never heard of Seaman CNC before. Not sure what you were trying to do with your machine but the 50w Raycus models are usually pretty good. NOT saying it's okay that they scammed you but at least you got something decent. Did you take any action to rectify?
@@LaserEverything I purchased it about 2 months ago. I was trying to cut thin aluminum which it was struggling with. I then opened up the system and noticed they removed the identification sticker for the laser. I used a power meter and confirmed it a 50watt. I paid 6k total for an advertised 100watt system. I may have to contact my credit company because it's a blatant scam especially since they clearly removed the identification sticker from the laser
1. I need to know how, when I buy the Mactron JPT Fiber engraver... what power should I start with by default? And then... how do I go about ordering the other power/workspaces capabilities to be included with my laser? They just give a default option of say 110x110 or 200x200 --- but I want to get as many additional adding as I possibly can so I don't have to make an order anytime soon. They have no add on conditional options on aliexpress, I also can't find where they sell add ons alone such as lenses etc. IF this is not an option how do you communicate with them by default? email? chat (which program?) etc.? Sorry to ask................ 2. I found the lenses linked on your site (TH-cam keeps removing my comments if I put a link) : "WaveTopSign 1064nm Co2 355nm 532nm M85 F-Theta Scan Lens 70x70 - 300x300 F100-420 for Fiber Co2 UV Laser Machine" : will these lenses be all I need for my Mactron 50w I intend on buying? ---- Also on your 50w Mactron Fiber link that laser no longer offers 300x300 anymore... so then I saw this option: (link removed) "Mactron Raycus Max JPT 50W Gold Laser Engraving and Cutting Machine With 300*300mm 700mm Tower Working Area For Metal Plastic" --- would it be even better if I started / bought this one vs. the exact one you linked in the Read More section of this video? THANKS!!! After I get my laser I'll join a membership.)
Normally I recommend starting with a 110 for new users. It will behave like what you are used to seeing from us on the channel. The Mactron lasers take every standard (NOT Opex) fiberl laser f-theta lens so no special consideration is needed. Get as many as you can. The lenses are cheap compared to the laser and it's extremely useful to have a spread of lenses to choose from for different situations.
@@LaserEverything so with the 110 when I want to go to 300x300 will I have to upgrade / change out the Z height (the lease height)? Seems like the 300x300 they are selling is taller?
I see plenty of product listings by Cloudray that describe the laser type they sell as "Raycus JPT" ... I'm confused, I was under the impression by your video that Raycus is one type and JPT is another? Please clarify if you can. I am possibly buying off of Amazon in order to take advantage of Prime type financial advantages.
You have to go out of your way to ask them now for a specific source. It's annoying. These guys were doing ok when I produced this but they've gotten a lot bigger lately and their customer service has been rapidly declining the last few months. I've been hearing a lot of complaints. I'd look elsewhere.

Mostly good information; however, there are important details missing. More important than the laser power is the per-pulse energy (PPE). PPE tells you more about the laser than just how much energy is in each pulse.

I would not buy a fiber laser that has a PPE under 1mJ.
Another advantage MOPA has over a Q-switched fiber laser is the ability to go below the optimized pulse repetition frequency (PRFo). PRFo is the frequency where both pulse energy and power are at their maximum. Below PRFo, power is reduced approximately linearily, and pulse energy is usually capped at the maximum (fun fact, in diode-pumped open-air lasers, pulse energy increases below PRFo).

I would argue that the Raycus systems likely have a cheap Opex lens, and this, combined with the low PPE is why these lasers have difficulties annealing. The Opex lens resolving power is crap; there is no discernable airy disc with these lenses; the laser is diffused too much, causing energy density to suffer. A Linos or Rofin-Sinar lens, having that large 120mm output lens, have wonderful resolving power, and this is why the IPG 20Watt laser, having a maximum frequency of 40kHz, can anneal all day long without problems. Yes, the Linos lens is about $1,600 more than the ~$50 Opex lens, but when you consider that you need to add more power with the Opex lens to get the same effect (energy density) as the Linos lens, it's cheaper to buy an expensive lens than to buy a laser with more power. Also important is the size of the laser beam going into the focus lens, as this is one of the parameters to the spot size algorithm. If the beam is small going into the lens, the spot will be large, i.e., low energy density. However, if the beam is large going into the focus lens, the spot will be small, high energy density. So, it's important to consider the complete system when talking about capabilities and applications, and comparing between systems. Stick a Linos lens on that Raycus, expand the beam to 8mm, and see what happens!
Finally, I want to clarify that IPG is originally a Russian company, that moved the headquarters to Massachusetts to have a better political environment to operate in. Yes, there are factories in Germany, and still in Russia, and yes, those Chinese systems that claim to have IPG lasers in them are really IPG lasers (manufactured in Russia). Most general purpose fiber lasers from IPG are manufactured in Germany, and I think that's what you meant to say; i.e., the German IPG fiber is the holy grail of q-switched fiber lasers. (For MOPA, SPI Lasers, now part of Trumpf, is the equivalent).

Awesome info Lance, thanks! I'll pin this for everyone to read!
any relation to Nikolai Basov?
Lance, So after everything you said, is there a laser you would reccomend instead? Is there one that is strong enought o engrave in metal and softer materials like wood? And any of them have US support?
Thanks so much in advance!
You're not going to find a laser that specializes in engraving wood and metal. CO2 lasers are used to engrave organics like wood acrylic glass and leather, fiber lasers are used to engrave inorganics like steel aluminum brass and copper.
Awesome info dear
Terrific video. You’re supplying people with limited laser knowledge with exactly the information they need to make an informed choice.
Glad it helped, thanks for the positive feedback!
I'm about to purchase one and they said laser source is Max and JPT and laser frequency is 20 - 80 kHz with cost 1500$
I have no idea but now I realized that I have to search for another, thank you for saving our time and sharing those details,
Check out the buying guide for some quality options, link in the description.
This is a great video and I've referred to it several times. Here we are in Jan of 2022, and I think the pricing is changing a LOT. A 100W Raycus Fiber Laser is now about the same price as a 50W MOPA. I know I'm going to want color if I don't have it, but a faster laser running 2x the power would also be nice. I'm in analysis paralysis!
It can definitely be hard too choose. Just know the MOPA colors are extremely inconsistent, difficult to master, and no one will be able to help you because variables like the temperature of the room can effect the outcome. Very steep learning curve.
I didn't have this information when i bought my machine but it looks like the research I did payed off. 100 watt JPT MOPA split from MORN. It works well from what I know how to do and this channel is helping a bunch!! Now I just need to do the conversion from the library you gave us for my machine and figure out the Q plus width setting. Thanks again!!!
Always happy to help, glad you got value out of it!
Great breakdown. I wish This video existed a couple years ago when I bought my 30w JPT MOPA. I could have saved a lot of money sticking with a standard, but I was sold on the colors before I knew the beautiful photos shown of color where taken at very specific viewing angles.
Yeah it's a bummer and definitely something everyone needs to know before spending that ridiculous amount of money.
I know it's the end of 2022 now, but I just purchased a brand new 30W Raycus Fiber Laser with a 200x200mm lense for $1,600 and free shipping from the USA! The seller was asking $1,800 obo on eBay for it because the Z Axis focus knob had gotten broken off during handling but they assumed the rest of the machine functions as intended and nothing else was damaged, so I offered $1,600 and they accept and they are even going to ship out a new focus knob for it. Honestly I'm not even worried about the knob as it looks like I'll be able to 3D print a knob for it no problem. And at the price I paid, that easily leaves me plenty of money to pick up a rotary and a smaller lens or two.
Glad you found a good deal on a used unit!
Why do some lasers have just a red box preview while others show the entire design in the red light preview?
Just check the box that says "Show Contour" down by the Light and Mark buttons! :)
Having never used or seen a fiber laser in action only on TH-cam I have decide to purchase one to hopefully enhance the Fountain pens I make, so I have taken your advice and ordered a Cloudray 50w JPT as you recommend them highly, at the age of 70 I think I will be seeking advice in abundance, Thank You.
Glad you made a purchase you're happy with, excited for you to get your new laser!
You have no idea how much you have clarified for me these options. I now know exactly what I need. Thank you so much! 👍
So glad it helped you Sanusi, let me know if you have any other questions!
This is super helpful. I almost bought the wrong laser had it not been for this vid. Thanks!
Glad it helped, starting to be outdated - will have to update soon ;)
@@LaserEverything I have notifications on so when it gets dropped I'll be sure to watch it. Looking forward to it.
great video but please drop the music in the background.
An old old video - music was rough in this one - we've since left it out our kept it SIGNIFICANTLY lower in our newer videos. :)
I have a 30 wat Max for over a year from HL Laser, no problems at all with the source.
Nice! Glad you had a good experience!
have 50 watt Fibre and 50watt CO2 and both are very very good, the 50 watt Fibre can and has easily burnt through stainless steel
Excellent!
Another fantastic post. I’m not flooded with info. Until I found you it was an info desert.
Glad it's helping you! ☺️ Thanks for watching!
What is the difference between the Q, QS, QE, and QB series of Raycus lasers?
I don't have a ton of experience with Raycus sources but you can definitely get that question answered in our Discord server: discord.gg/dvu8PFjW
Thanks for all you did .. I am so happy to see all your videos, you making it usually. its very usful and teaching others. its so genius and helpfull. Wish i know most of this infomation befoer buying my fiber laser. waiting for you to buy the UV laser and start your journy of expermets .. good luck Bro.
We're getting really close on the patreon! Hopefully we will be able to pick the UV up soon and we can get started down that road as well. Thanks for your unwavering support Daifallah!
All i need to know is what would be good for clean detailed scroll work on SS ? Yes I’m talking about firearms. My thinking is if I purchase a machine that can do that without issue , it can do a lot more I may need- various text, knotwork,simple images simply . I’m assuming there’s been improvements since 2021 also.
Great informative video in 2023 too. Looking for a Fiber laser for jewlery, i will go for the 30w and 110mm lens to do the job. Thank you!
Great info vids for sure, really cleared up some questions I had. Editing was spot on with the dual audio as well.
Glad it helped you out :D Thanks for the feedback!
Where can you just buy a 50w laser and power supply by it self?
I already have a CNC table I want to use, but don’t need a separate machine.
You could check out wavetopsign on aliexpress. They're my favorite vendor for sources and power supplies.
What do you think of the EM Smart One Laser?
Learned a lot. Saved the video and subscribed. Thank you.
Thanks for the sub! Glad you're getting use out of the content Mark!
What would you recommend for polymer. Kydex. Injection molds. I make custom holsters and want to put my logo on the clips and belt loops.
Sounds like a lot of plastics, in which case I'd be looking at a UV laser. 3-5w should do the trick.
@@LaserEverything so will the have the same affect to a p mag that you had with the gray tan and brown.
My friend, do you use an outlet plug of 220 volts or 120 volts because in China they use 220V and the videos they show us are of a fibre laser with a 220 volt power? Only 120V is used in the United States and Canada. Unless you have a 220 to 250V special outlet installed. Also if a 120V 50W fiber laser was to vs a 220V 50W fiber laser what would be the difference in terms of engraving on jewellery metal and quality of products etc....
We use 120v. There's no difference in terms of the actual engraving. The 120v systems pull more current to meet the wattage spec but it doesn't effect the operation of the laser or what they're capable of, since everything is transformed by PSU's to DC inside the machine anyway.
I need it for gold cutting bangles how much power i should go far. Also can I use this with galvo head
So I have a limited budget. I can afford either a 50w JPT or a 30W JPT mopa. The color aspect is very cool, but the 50 is faster and can deeper engrave, right? Any advice? Thanks.
Correct, and personally I'd go for the 50w LP any day over the 30w M7 if those were my options.
Maybe or probably it's a dumb question, but, I want to know as much as possible.
I saw how the fiber laser machines how can they work, and, of course, the galvanometer is the optimal way to mark fast or engrave using the fiber laser beam.
But, what happen if I want to mark multiple drawings over a stainless steel sheet, 2.44m * 1.20m (for example), the station's space is not enough to be possible to work these dimensions.
If I want to build a cnc machine, can I just buy the fiber laser source and "power on" / "power off" when it's required according to my motion requirements ?.
I don't know if it's mandatory to buy and use the control board included with the portable or workstation versions to be possible for me to control the fiber laser
according to my needs (enable/disable the power beam required), and I don't know if I can ignore the presence of the galvo and use only the fiber source
and execute some testings (assuming I can control it without issues).
I don't know if with some changes, "S" parameters inside gcode can be changed and assuming there is some kind of bridge between the motion controller and the fiber laser (with or without it's original controller) it could be possible to "invoke" the required power beam.
¿ "Pros" and "cons" about this ?. I'll appreciate any comment that you can give me... I'm just trying to figure out if it can be possible. Thanks in advance !
It's possible but reflecting 1064 in a gantry system is kind of a rare special use case. Epilog does it best with their Epilog Fusion machines which come in very large bed sizes. I'd look into a system like that if you need to work on spaces that large.
@@LaserEverything Thanks for the info !
I think Raycus product is mostly at 1000w level, with wave length at 1080nm, which is 285M Hz frequency. User can easy blind himself even with eyes closed, even only facing the light spot on the wall. It is not for hobbyist.
Their cutting sources sure, but they make way lower powered pulsed sources for this application as well from 20-100w
wow.. now I understand some of it. I almost purchase the cheaper ones.. now I can reconsider it . 👍 thanks
Great Information. My question is what laser you would recommend buying to engrave on golf clubs??
A 30 or 50w fiber laser would do well. Check out some of the links in the buying guide over at www.lasereverything.net/buyingguide/
Portable laser weld machine? Any example to read more info? Interested
Hi Alex, FYI, I purchased a Mactron JPT 50w laser. I checked the model number of the laser source: YDFLP-E-50-LP-L-R. I did a search for that model number and it is listed as a MOPA pulse fiber laser. This appears to be the source when ordering the JPT. Thought you could use that bit of info with your recommendations. The case appears to be the same build quality as your new CO2 galvo unit. Thumbs up for Mactron for constantly improving their product line.
Yep all JPT are technically mopa on some crazy science level I don't understand. The LP series is what we would consider q-switch though. Solid standard unit. Glad you got the updated casing. It really is nice and shiny huh? Can't wait to oogle at it some more tomorrow!
That's interesting and I must investigate further as my "non-MOPA" JPT 50 will produce various colours in steel. Hearing that this feature is unique to mopa makes me wonder. (pleasantly).
Just got my Fiber laser last Friday. Raycus laser with 20 to 60 range
Congratulations!
What do you suggest? I want one of hobbies small stuff but also need to engrave handguns and rifle parts. And glass. Maybe cut wood if anything but over all what’s the best one in your thought?
Hello, can you speak to units for "laser cleaning" technology?
I have a specialized application for removing mineral deposits from ceramic and/or cementeous surfaces without etching the substrate.
The German IPG sounds intriguing as the ability to choose color would be valuable not to mention integrity of beam.
Manufacturer(s) you'd suggest?
THANK YOU! I had been looking for an easy to follow and thoroughly researched fiber laser explanation and you are it.
Happy to help! I also highly recommend our podcast episode on 5 tips you need to know before importing a laser! Really good info in there for you too! Available on all podcast sites and the video version is on our youtube channel.
@@LaserEverything Thanks for the response. I prefer to buy locally in India so I can avoid warranty issues. Prices are similar but I want to go shopping armed with the knowledge about subtleties like MOPA and laser sources you explained. Tons of companies in India too trying to pass of some cheap chinese laser as "IPG".
What I’m looking is a laser that can cut really thin metal for watch parts with precision! Could recommend or do a video about something like that? I don’t need to thick metal!
30w or 50w laser should be fine depending on the metal. Small cuts on thin metal are easy for most fiber lasers.
First, I was ecstatic to find this video!!! I'm in the process of starting a business that will heavily depend on laser engraving. I've been doing my homework on various fiber lasers in general, it's great to see a knowledgeable channel that isn't manufacturer sponsored. I did already know that I need a MOPA Fiber laser. That said, your breakdown really cleared up a couple of things for me, especially in relation to pulse frequency. Quick question, are you familiar with LaserStar? If so, what do you think of their products & services? At any rate...back to binging on your channel!
Not familiar with LaserStar but before you commit to a brand DONT SKIP ON THE PODCAST - go watch/listen to every episode of it like, right now. Most important info before buying a laser can be found there. Lots of perspectives, experiences etc we get really specific. Highly recommend it!
@@LaserEverything Will do! I have one other question for you that I can't get a solid answer on. I know MOPA lasers can engrave color on stainless steel, titanium, and a few other metals for sure, but can it do it on aluminium as well or only shades of grey?
The colors are the result heating the iron in ferreous metals. No iron, no color!
@@LaserEverything Gotcha, thank you!
Hello what are the parameters laser on Tc,laser off Tc,end Tc,polygon Tc,please help me,thanks
Those are called laser timing settings, check out this great video by JefferyJ on the topic: th-cam.com/video/KKmpiMiHXjg/w-d-xo.html
I purchased a 50w raycus qb fiber laser marking machine 8 month ago and 2 days ago it just stopped working so i took it to the seller and he said that the laser source is burnt and there is no warranty for that, i never used it for more than 6 hours a day and never used power more than 95% ,please tell me how did it got burnt and what's the meaning of that. I am helpless right now😔😔 it's only been 8 month. Is there a way to repair that laser? Please reply
That response doesn't really make any sense to me Mohd and the source should absolutely be covered under the warranty so that's a scam. Please join either our discord or facebook group (there's links in the video description) and make a post so we can take a closer look at what might be going on.
I don’t have a fiber laser so I cannot check this but I had a thought that since borax is sodium-based (a metal )
Wood or birch plywood treated with borax might react to a fiber laser engraving.
Could somebody, back thank you
I'll check it out and see if it helps. If it does it's a work around, still won't provide anything near the results you're going to get with a laser designed for organics.
I have one question I would like to understand, can this fiber laser engrave on acrylic or clear painted acrylic or white painted acrylic to obtain that backlight?
Thanks for the review, it really help clear many thing for getting into fiber laser
So glad it helped you!
Can you recommend me a mopa machine for starters? Thanks
Can I cut a 1 mm copper sheet with 50W Fiber Laser machine? what settings do you recommend?
Could you help me with getting the best laser for my application. I make silver hand pours and am looking to engrave portraits on the bars and don't have a clue what to get.
For silver you really want to be looking at 50w+ as it will reflect a ton of the 1064nm laser light.

What should I get if I want to start engraving firearms including rifles
Firearms are actually pretty easy to work with so you should be able to use just about any system. It's more about the size of the parts you want to mark. The larger you want to do in one shot the more power you'll have to have to drive the larger lenses.
So is Trotec Sppedmark fiber lasers just a raycus rebranded and utilizing their software?
Is there a way to use speedmark with a raycus laser?
Everything Trotec produces is proprietary. While they may use some common laser sources, their controllers and supporting hardware are required in order to take advantage of their software so unfortunately the answer is unlikely.
Hello. I can confirm that with a 30w Raycus you can anneal steel with the right settings, deep back and fast. Actually, i have hot Mopa 60w and the black isn't deep black as than with raycus
Nice, you should join the discord and share your settings with the community! :)
@@LaserEverything hi, i send you private mail .
I have a nice price for a JPT MOPA 60w engraving machine. If I am correct the MOPA can do anything a Fiber laser can do, just that it also offers some additional settings like the pulse width? I am mainly interested in black engravings on steel. I just want to be sure that i am not buying something that will not be so powerful for black as lets say a 50w raycust or an ordinary jpt laser? Thanks. also, ofcourse i want to experiment with colors on steel in the future.
Hi Tim! Any fiber laser will be able to mark black on steel.
@@LaserEverything thanks. i am considering 60w jpt vs 80w jpt - what can 80w do what 60w cannot? are there any disadvantages of more power? (finesse,beam width or something like this?)
This is a great. Thank you so much. Any idea what I need for engraving polyurethane thermoplastic material. This are for for medical and dental applications.
I plan to buy one for jewelry business, I looking for less complicate to use and which watts you recommend and brand with good price? Thank you.
The Mactron is always my recommendation. JPT for high frequency and 50w is good for defeating precious metal reflections. Link in the description or check out the laser page on my website for more info
www.lasereverything.net/lasers
I'm working with a 30w ipg mopa. 4ns -200ns
Machine is a +GF+ LP1000U
Can you tell me which fixed pulse rate your standard 30w fiber has?
Everything is based off 200ns
Can you please recommend a Fiber Laser that will engrave gold/ silver / other metals for my jewelry busienss . Under $3,000. Thanks
The only laser I'd check out as of right now would be one of the EM-Smart units. Get as much wattage as you can afford. That's as small as I'd go. Jewelry can be particularly reflective and can require very focused power to ablate sometimes. Here's a link to our review of the Basic 2R: th-cam.com/video/er8vi_uCcgY/w-d-xo.html
I'm looking for a low-cost recommendation for a laser to mark 1" tungsten carbide tool bits. Which one should I purchase?.
You aren't going to go crazy deep super fast, but something like the 30w mactron linked in the description would be sufficient.
I Just ordered a Cloudray fiber laser marker with a 30W JPT LP-series laser source, and are a bit confused. Is the JPT LP-series a MOPA laser? If it is a MOPA laser, it seem to me that JPT only make MOPA lasers. What is the different then between the LP series and the M7 series?
While the LP units use MOPA technology to manage their frequencies, the pulse duration is locked at 200ns. With an M7 that pulse duration is unlocked and a new variable is able to be changed. LP units are not "true" MOPA lasers in practice.
hi your video has helped me a lot in selecting the right laser. i think that the 50 watt jpt laser is the best
The best all arounder for the average user for sure!
i want gold cutting that have many design like earing ring and many more i want what was actual loss of gold cutt by laser any idea ?
I didn't measure but there was quite a bit of loss. You would want to use something like a fume extractor to capture the gold dust lost in the process.
What will it be good mainly for imprinting stainless steel/metal bracelets? Do you recommend something else? Can you do on a round surface like cups?
Most fiber lasers these days come with rotary tools to do round items. Fiber lasers can mark any metal.
You can find our updated list of recommended machines at www.lasereverything.net/buyingguide :D
Can a 60w mopa laser engraver do deep engraving just like a regular fiber laser just with the color options
Yes absolutely 100%
Im looking to add one to my gunshop for enfraving & stipping. Im told I should I should go mopa? Will a non mopa stipple? Thanks
A non-MOPA WILL stipple, but a MOPA would probably be significantly easier.
Can a split system fiber laser shoot "upward" so as to mark (engrave) the underside of a steel welding table (IOW, rotate head 180 up)? 🤔
Yeah you could theoretically turn the galvo head upside down on your unit. Doesn't really matter which direction the galvo head is pointing, the light doesn't care what direction it's shooting.
Hello Alex, I have a little question for you. Can I know what the laser machine will be to customize credit cards? Please...
Hi, I don't personally do this but there's people posting about it on our FB group and Discord! You can try there!

Do we need air-conditioning while using a 50w JPT lazer machine?
You shouldn't unless it's really really hot. Like 90+ F I would consider it. Make sure the vents are clear and the fans on your system are all working but it should be okay.
Thanks a ton
Hello. Would you have this information that you said in the video in text format? Because my English is very weak and TH-cam insists that you are speaking in Vietnamese, then the automatic translation is crazy and nothing is understood.
Does anyone know what kind of power you need to run a mactron jpt 50watt laser? And if that is a good one to go with
A standard 120V outlet should do it - 220 I believe if you're in the EU.
Hey Alex, I really appreciate all of this information. Truly and amazing wealth of knowledge. I have been following you for some time, but never purchased. I recently (impulsively) purchased a Laser Pecker 2. It was a good little machine but can’t even get close to what I want to do. To keep story short I returned it and am looking at at fiber laser with atleast a 30w raycus. What’s your thoughts on Omtech and Monport? They seem pretty reasonable on price and I’m really trying to stay on the lower end of budget. Thank you in advance!
I haven't had my hands on either of those lasers unfortunately. We do have a buying guide on our website with machines we have in our shop and can recommend.
I want lser cutting machine
Application is work on carbon steel material which is used in making a embosing die.
This isn't a cutting machine and it shouldn't be used that way. It can cut very thin very soft metals only - otherwise you're gonna have a really hard time. Use these machines for marking and engraving only.
@@LaserEverything pls suggest me
Which brand fiber source and galvo used in 3D 50 w laser m/c
Can annealing be achieved with a 30 watt JPT Fiber machine or does it have to be a 50 watt machine or higher?
Absolutely. 30w works fine!
@@LaserEverything Thank you so much for responding. I really appreciate it.
You got it 🙂
Have you tried color laser engraving? How does the piece engraved with color react to rust and corrosion?
Color markings if not properly sealed can be significantly more prone to rust and currosion than your typical laser mark.
I want to marking gold 20w. which will best for me.
Gold is really reflective. I'd recommend at least a 30w. The 20w will do it but it will struggle. I always recommend the Mactrons which are linked in the description!
Do you think 30w is capable to cut 1.5 mm thikness of gold or silver plate?
HELP, What do I need for Only Engraving Urns 90% Brass? I was quoted over $18,000 for Ap: in addition can I use Gerber Omega design software or do I need to spend more money on software????
Brass urns can be engraved with any standard fiber laser. Getting around the curves will be helped by getting a higher wattage machine like a 50 or 60w with a large lens size like 200mm - 300mm. I would put your budget at $6,000 - $10,000
Can we “cut” metals that are around .02 thick with a fiber laser? Great video btw.
.02 doable but it takes a while. Galvo lasers aren't designed for cutting.
@@LaserEverything Any idea how many passes it would require? I'm looking into a fiber laser, any idea if Biss Fiber lasers arw good?On the other hand they make a desk top wet jet cutters for 9g. I'm blown away at how much commercial wet jet cutters go for 80g, 150g, 250,000.
How would I go about getting your library setting for my 30 watt fiber laser?
The parameter libraries are available to everyone who supports the channel over at masters.lasereverything.net/ ;)
My working area is ranging from 50mm L X 50mm W up to 300mm L X 300mm W on the minimum of a 0.2mm thick copper sheet. Can I engrave using only a 50W lens on various sheets without cutting through or do I have to change lens accordingly?
The larger the lens the weaker the beam is going to behave. I usually recommend using the smallest lens you can fit your artwork in.
I am looking a purchasing the Mactron 30W JPT Fiber Laser. What size table should I get, 70mm, 110mm, 160mm, or the 200mm. What lens should I request also?
Thanks for any help that can be given.
get one lens with your mactron fiber, doesn't really matter which, then get the rest from cloudray
I recommend starting with a 110 on the 30w that's my daily driver
the rest you can get from the links on the buying guide www.lasereverything.net/buyingguide for a Mactron unit you want the "Standard" lenses not the OPEX
I have a 50 watt JPT source fibre laser. Im having trouble with cutting sterling silver with brown fleck markings (like burn marks) across the surface which dont diasapear after sanding, pickling, polishing etc. Has anyone else experienced this?
Sounds like spash damage. I'd reduce your power, increase your speed a bit and increase the diameter of your wobble to assist in cutting. Low and slow yields cleaner cuts - even though they take longer.
@@LaserEverything thanks ill try this!
Hi guys I hope you can help. I have sliced an stl file for my 60 watt 2.5d MOPA laser and started to run the file. Everything was going well until it hit layer 94 then it will not go any further - can you help and how to fix. I am using Ezcad3

@@LaserEverything thank you will post on the community page.
Would you get a 30W JPT laser or a 50W Raycus laser?
Depends on what you plan to use it for honestly. If you need raw power I'd go with the Raycus. If you want more fidelity I'd go with the JPT. Either will be great though. If I just had to pick right now without more info I'd probably go with the JPT.
I have a 30 watt raycus but I want a 50watt for stainless steel where did you get your JPT
Mactron, link in description or check out the buying guide www.lasereverything.net/buyingguide
i have a portable 50w one with a range from 50 to 100khz. only problem is i don't get what the frequency does and don't see any difference while marking under any frequency. anyone care to help?
The higher the frequency the more pulses the laser is doing. The shorter the pulse the less power can fit into each pulse, but the more of them there are. It essentially "softens" the blow each time the laser pulses. Higher frequencies tend to heat metals, lower frequencies tend to ablate them.
@@LaserEverything thank you very much, helpful! Also, what do the settings under the speed and freq mean? I see everyone has them 100/300/100/100 but just mine are -180/200/50/50
Check out the video we just published on Laser Timing - it goes in depth on this topic.
If you buy a Cloudray laser from Amazon or from cloudray directly which is cheaper. I am looking at a 50watt JPT MOPA laser at both from amazon (Cloudray) and cloudray's site. I asked them if there are any extra fees that needed to be paid over the price shown, they said there would be taxes to pay but would not give me any kind of idea how much those are. I assume if you buy one from amazon all fees including shipping are included. Any help on this would be appreciated, i joined your 8 dollars a month program yesterday, thank you for any guidance.
Yes that laser from their website would almost guaranteed cost you duties which can be up to 30% of the price of the laser depending on where you live. The price difference is substantial because the duties are already paid on the Amazon machines because they already had to be imported likely stored in a local warehouse. At any rate I really don't recommend the cloudray too much anymore. A lot of members of complained to me over the last six to eight months about their quality and customer support. I'd check out some of our other recommendations instead. There's a link to the buying guide in the description.
An excellent breakdown! Very very detailed. Loving your content!
Thank you, glad you got value out of it!
I am looking for something to do scroll work on gun slides. Nothing crazy out pocket. What do you suggest
We have a link to the buying guide in the description :)
Okay two- 50-watt machines with different frequencies one sales for 6,000 and the other for 4,000 what's the difference
Hi, what do you rrecommend for a vintage and classic car restoration business in terms of rust removal, paint removal etc
I bought a seaman CNC system which was supposed to be 100watts. Just tested power and looks like they put a 50watt RAYCUS and only makes 46 watts with or without lens and directly from coupler. Got scammed
That sucks dude I'm so sorry to hear that. I've never heard of Seaman CNC before. Not sure what you were trying to do with your machine but the 50w Raycus models are usually pretty good. NOT saying it's okay that they scammed you but at least you got something decent. Did you take any action to rectify?
@@LaserEverything I purchased it about 2 months ago. I was trying to cut thin aluminum which it was struggling with. I then opened up the system and noticed they removed the identification sticker for the laser. I used a power meter and confirmed it a 50watt. I paid 6k total for an advertised 100watt system. I may have to contact my credit company because it's a blatant scam especially since they clearly removed the identification sticker from the laser
Yeah man that's no good at all, definitely have to look into that. Totally unacceptable.
Very helpful video about laser marking machine using methods
Thanks a lot
Keep it up! Really appreciate your work!!!
I'm glad it's helping you!
1. I need to know how, when I buy the Mactron JPT Fiber engraver... what power should I start with by default? And then... how do I go about ordering the other power/workspaces capabilities to be included with my laser? They just give a default option of say 110x110 or 200x200 --- but I want to get as many additional adding as I possibly can so I don't have to make an order anytime soon. They have no add on conditional options on aliexpress, I also can't find where they sell add ons alone such as lenses etc. IF this is not an option how do you communicate with them by default? email? chat (which program?) etc.? Sorry to ask................
2. I found the lenses linked on your site (TH-cam keeps removing my comments if I put a link) : "WaveTopSign 1064nm Co2 355nm 532nm M85 F-Theta Scan Lens 70x70 - 300x300 F100-420 for Fiber Co2 UV Laser Machine" : will these lenses be all I need for my Mactron 50w I intend on buying? ---- Also on your 50w Mactron Fiber link that laser no longer offers 300x300 anymore... so then I saw this option: (link removed) "Mactron Raycus Max JPT 50W Gold Laser Engraving and Cutting Machine With 300*300mm 700mm Tower Working Area For Metal Plastic" --- would it be even better if I started / bought this one vs. the exact one you linked in the Read More section of this video? THANKS!!! After I get my laser I'll join a membership.)
Normally I recommend starting with a 110 for new users. It will behave like what you are used to seeing from us on the channel. The Mactron lasers take every standard (NOT Opex) fiberl laser f-theta lens so no special consideration is needed. Get as many as you can. The lenses are cheap compared to the laser and it's extremely useful to have a spread of lenses to choose from for different situations.
@@LaserEverything so with the 110 when I want to go to 300x300 will I have to upgrade / change out the Z height (the lease height)? Seems like the 300x300 they are selling is taller?
Hi, how I am not seeing material listing on param library of my ezcad2 ?
The lasers don't come with parameters for free, you have to make up your own.
I see plenty of product listings by Cloudray that describe the laser type they sell as "Raycus JPT" ... I'm confused, I was under the impression by your video that Raycus is one type and JPT is another? Please clarify if you can. I am possibly buying off of Amazon in order to take advantage of Prime type financial advantages.
You have to go out of your way to ask them now for a specific source. It's annoying. These guys were doing ok when I produced this but they've gotten a lot bigger lately and their customer service has been rapidly declining the last few months. I've been hearing a lot of complaints. I'd look elsewhere.
