Never have I needed that stupid fire suppression system with ANY of my lasers in the years I have been running them. I have cut cardboards on all of them and many, many other materials. I run a business with C02 and Diode lasers, the only small fire I had was when I was testing a specific kind of door mat that used Coconut hairs and I was right there because I knew the risk as I DID MY RESEARCH. Also, having to run the file from the machine button, that is on LTT for buying without doing their research.

They preach that we speak with our wallet and they do not follow their own advice.

Are you kidding? If they let Linus have his way with this machine, he'd either drop it destroying a several thousand dollar laser machine, or he'd burn the place down, and find a way to sneak in a penis joke in there somewhere, cause of course, he can't but help himself to go there, even though his company just fell under serious levels of scrutiny.
I appreciate the seizure warnings even for small flashes like in this video. Having an epileptic child, little things like this really do help in day to day life when it comes to little things like enjoying TH-cam. Thank you.
He let the laser tickle the edge of a single board and then whinged about safety the other 17 minutes. They need to do better than that. Other TH-camrs that review these machines on weekly to daily basis do far more. Grid power tests, cut tests of various thicknesses, engraving on metal, plastic, paper, felt, cardboard, they test the rotary unit, the efficiency of the extraction from the manufacturers enclosure and so on.
@@FuttFel safety should be #1 priority, everything else is secondary. *after* you have a guaranteed safe system, the ability matters (especially for consumer devices such as this)
@@isaachenrikson3197 Of course. I have a 22w diode laser on the way and I ordered an enclosure and extraction system before even receiving the laser. So the video should've been 25 mins then. 10 mins about safety and the rest should've been about what the laser can do.
@@FuttFelI think the reasoning is that Tynan wanted to make the video more about the safety (or lack of) of these hobby laser machines rather than the product itself
So he wasnt actually reviewing the product. Ive worked with 120W industrial lasers and the ammount of effort he is going through for safety is over the top, What I would recomend for a machine like this is to YES buy the expensive safety glasses as the number one thing. then afterwards make a heavy lunch, sit down and read the manual as you eat said lunch. the follow and do everything the manual says keeping common sense as the number one protector of your safety, IE dont put your hand in front of the laser to find out how hot it is.@@isaachenrikson3197
Listen here LTT, THIS IS EXCELLENT CONTENT. He didn't just break down the tool, he taught me wide safety concerns when working with lasers. Even if it is in generals, I feel much more informed when looking for a product, what to consider. Can you please do a series with your engineering staff where they walk through purchasing and safety considerations for CnC's, Laser engravers, etchers, etc. Think "Etsy Safety" cause lets be honest, all of us have a side hustle now a days. I've used laser engraver before (low watt), and never considered half of the warnings he gave in this video.
The scariest thing about laser cutter/engravers systems generally and open-frame setups like this in particular is the fact that human vision has a lot of failsafes and compensation mechanisms built into it, and you have to do a _LOT_ of damage to your eyes before you actually begin to notice. It's not uncommon for people that work with lasers to have retinas the look like Swiss cheese but are still able to "see" more-or-less because their brains are editing out the blind spots. To give an idea how dangerous a setup this really is: _The light from a 40W blue laser will almost instantly burn a hole in your retina just from the dot of laser light reflecting off a white wall._ One of these days I might build myself a laser cutter/engraver, but if I do it'll be a fully enclosed box with an optically shielded camera inside to use to see what it's doing, and safety interlocks galore so it won't kill my peepers.
I have a green laser pointer. Only 5mW. I still treat it like an eye hazard even though it's not powerful enough to be one because holy _crap_ it's bright to the eye.
Personally, I think the hysteria over laser cutters/engravers is over blown. I regularly work with a 2500 watt CO2 laser built by Cincinnati that has no issue cutting through 3/8" stainless. We've ran it for 15 years without an enclosure. Just don't be dumb and you'll be fine. It's the same with any tool you purchase. These small lasers aren't any more dangerous than an angle grinder. That's not to say an angle grinder isn't dangerous. I've personally seen an inch long metal wire sticking out of someone's eye, which had to be surgically removed, just because they forgot to put their glasses back on. But go watch any review video of an angle grinder. You won't find the same hysteria. People tend to handle self-preservation just fine on their own. Those that don't, will end up hurting themselves even with you telling them they need an enclosure.
@@NG-VQ37VHR _" Just don't be dumb and you'll be fine."_ Have you _talked_ to people lately? _"Dumb" is the norm._ These are being sold to Joe & Jane Sixpack, who more than likely don't have any actual experience working with eye-hazardous lasers. The threat profile here is that you can get eye damage and not even know it, and in a home or home-workshop environment you have secondary victims (e.g., family/pets) that can also get hurt without realizing it. A hopefully-trained professional working with a commercial system that will almost certainly have integrated safeties (for example, I'd wager your CO2 system has interlocks to keep things like fingers out of the beam path) is a whole different animal than an amateur with a basic consumer system that has no real safeties to speak of aside from a little plastic shield around the diode's output end.
@@NG-VQ37VHR IMHO the main issue is that a laser seems fun and tinkery for everyone. Oh you can make nice wedding cards and wood puzzles. Theehee. An Angle grinder is loud, noisy and scary because it is a rotating machine. Laser? Probably fine because it has a tinted glass and I have fancy googles. Yes, both are dangerous. So is a kitchen knife. But you know a kitchen knife can be sharp as heck or stab your leg if it falls. Because you were taught properly. Laser? Oh it's just a 3D Printer or a cutting plotter with a laser instead of a knife. What could probably happen, right?
@@NG-VQ37VHR The hazard of cheap laser cutters like this is party psychological. An angle grinder is loud and scary, and spins really fast. It commands a certain level of respect even in many people who know nothing about it, and mechanical hazards are in general more relatable for most people. But high-powered lasers are something that most people have no concept about, and something that fits on your desk, relatively quiet, etc. does not put the fear into people nearly as much, and hazards like reflected light are not as obvious.
Very much this. I don't know how much of this was planned/shot/edited before or after the recent break, but... If this *is* representative of future video plans, my interest is piqued. The focus on safety, the pacing, and the tone of the whole thing really made it a nice watch.
Love the return to substance over style. No flashy editing, a healthy respect for the subject matter, lots of good information. A video you watch to actually learn something rather than just let play in the background.
This is probably my favorite ShortCircuits. Super informative, done by someone who seems well educated on the subject, and gives an honest take on the product.
I love the goofiness of LTT in general, but damn I would love to see more videos with Tynan that are just a tad bit more serious.. Imagine what this man could do with some of the watercooling projects 👏💪
What a _calm_ Linus would look! And easy on the eyes and ears ☺️!! Safety above all else. Would like to see other examples of what the laser can do. Thank you for the video!
we use Lasers on my Workplace and i cant stress enough how bad of an idea it is, to use them without an enclosure. id go further and say that the Enclosure they provide is way to cheap to trust it 100%. if id need to have a Laser at home, id be using Webcams as "Windows" and would built the Enclosure without any physical windows. Also the Enclosure shoud have a Detection if the Panel is open. and if it is, it should cut power to the LaserHead And requiring to press a button INSIDE of the Enclosure, so you have to start the Laser without the Enclosure closed is Highly Dangerous and Dumb... Nice ShortCircuit and all of your concerns are 100% the same as mine
I agree that these “cheap” lasers just aren’t worth it in the end and are shockingly dangerous to the end user. Ppl just want to be cheap and ignore the safety aspects of these things in order achieve said cheapness.
The level of electronics/electrical skill required to re-wire that button to the outside of the enclosure is pretty low, but again with the 'why is this even sold this way?'
@@mycosys youre right. its not RocketScience to move a Button. BUT, ignoring the fact it could be bought without an enclosure, there SHOULD be a Header/Connector for a button wich should be integrated in the enclosure. yeah 200$ is way to cheap for an enclosure which meets all Safety Criteria like i said before. but if somebody buys one for safety reasons, there should be an integrated 10ct Button with a long enough cable to just plug in. i hate it when Manufacturers cheap out on cent-parts making the end product way more unsafe due to "supposedly safety" where no safety is. to loose sight it doenst need minutes, it needs fractions of a second. imaginge someone wants to etch metal, the laserbeam reflect off the surface in the first second while the enclosure is still open to start the process... yeah its maybe dark thoughts but theres a Reason LaserEngraver/-Cutters need to match so many certifications in the Industry
Tynan is easily one of the best presenters at Linus Media since Luke. None of the overly hyped cringy reactions. No silliness for silliness' sake. Just good presentation, information and real, human interaction. 10/10
@@DizzyBusy I don't mind some silliness in balanced amounts, but of late it has been more and more short attention-span grabbing random fluff punctuated by shrill, ear-bleeding squeals, crashes bangs and forced exclamations (that the editors don't level out properly, thus making them literally painful to listen to when they peak) Yeah I'm an elder millennial, so a lot of it is just me being old and not vibing with the kids' love for hyper-reactions. I liked the Linus/Luke balance back in the day, and I liked how at first they seemed to keep that with new presenters, before it became balls-to-the-wall content for content's sake. I hope that that will return now that they have had their recent introspection.
This video made me realize that I’ve been letting LMG videos play in the background. It feels like it’s been a while since there was a video that was actually worth actively giving my attention to. Really glad we are going back to quality videos.
IKR? I am really loving the new quality video's like this, no more of that cheap garbage that they were spitting out just to maintain an unrealistic 25 video quantity every week BS. This is the quality we deserve if they want to keep us as viewers. I really loved this segment, and Tynan deserves to be in more video's IMHO!
Serious without being dry and very relaxing yet informative. Well done Tynan and team! Got sick and tired of all the goofing around from so many others. I don’t mind some goofing but so many reviews were just nonchalant and seemed more like a high school project than a review. So far Tynan and Dan are absolutely excellent choices as hosts and the script has quality to it. Keep it up LMG 👏
This company is either very confident in its users' ability to perform their due diligence about safety precautions, or they are very confident in their lawyers.
Achievement get: Have a comment featured on an LMG channel! Seriously though, thank you for producing this in depth follow up hosted by someone who knows what they are talking about. I am not faulting Linus, Yvonne, or those who helped put together the video, cheap laser marketing preys on people who want the tech without knowing the important safety considerations; I hope they built an enclosure or replaced that machine. The conclusions here are solid: these types of unenclosed, high powered lasers are simply not safe, and really should not be used by people who don't know what they are doing. I like that this xTool system is trying to bring a safer laser system to a lower price point, which is definitely better than the super cheap extruded aluminum AliExpress kits, but it should all be sold as one kit. I still fear someone who doesn't know better thinking they dont need the extra safety equipment and hurting themselves. And the people who do know better are probably looking for a more professional laser system as you alluded to in your video.. I am glad that the lasers I work with are fully enclosed with professional grade fume extraction. We only have one set of eyes people, stay safe!
For leather, make sure it is vegitanned/naturally tanned. If the leather was quick tanned with chromium, it could be problematic for laser cutting. pretty sure its mainly nasty off gassing but, the laser and the chromium don't interact well.
A 40W laser for hobbyist, with questionable safety glasses and an optional enclosure. Very dangerous. This thing should have a fixed, interlocked enclosure.
Okay this was a great video. I learned a lot and I appreciate the focus on safety because I have a laser cutter on order and I learned things I didn't know I needed to know Give this host and writer a gold star and a gold xbox controller
Laser cutters can be amazing tools as long as the risks are understood and managed! If you are ever unsure it’s worth doing a bit more research or taking an extra precaution
Big note on the "real leather" this is incorrectly phrased. You want to make sure it is VEGETABLE tanned and NOT Chrome tanned as this will release chromium gas which is toxic.
I'm not a longtime viewer and I can appreciate the fast pace and goof-level of LTT as a form Of entertainment but this video is a really good example of the kind of video I appreciate most! People who are majorly into DIY and Maker culture telling me about their particular interest!
Ok, this is probably the best laser video I've watched so far. This with Maker Muse's video on what you should and shouldn't use on a laser make for a great pair. Thank you for making an in depth video on how to use a laser properly. It is interesting that with all of those features, the Glowforge ends up being a better value and with a better enclosure. Not sure about their fire suppression system though. I don't know if this video has been in the works for a while, but I'm glad it's out now after the controversy. This is a great direction to go for discussing potentially very dangerous tools that aren't obviously dangerous to some people (versus something like a table saw where anyone knows to stay away from it).
I’d have to disagree. I felt like he just opened the box one day and decided to do the video. It looks almost like no research was done and he did not have a good grasp of understanding the basics of the machine. For instance positioning is 101 and spelled out in the software when you go to process it. There was nothing in depth to this. Safety is important and I’d never fault anyone to go above and beyond what they need, but the shields and glasses are rated for safe use with these. They’re made for reflective or stray beams. If you have someone pointing the laser directly at your eyes then there’s something else wrong.
I wouldn't even put in a window in my enclosure but use a cheap camera sensor with a cheap lens to the outside with a screen on ( and good thing about the sensor and lens being cheap is that if it break/die from some odd reason its easy to replace) and since it's a camera and a screen there is absolutely no way that all the bad rays gets through to my eyes
As "monotone" as this is, I absolutely love this video. Its someone that understands the tech and the safety, and I wouldn't be surprised if Tynan insisted that the camera op and anyone else nearby wears the safety goggles
That’s a great laser. I use it daily as well as many other lasers depending on what i am working on. I do hate the lasers without enclosures. Do prefer Co2 or Fiber.
@@DracolegacyOfficial This is meant for China or the third world in general where we don't care/obsess about safety. The little shield surrounding the laser is meant to protect against direct reflections, and combined with the glasses, that's considered more than enough.
I have a 5W D1 from xtool and the first thing any owner should do is ditch the awful XCS software and use Lightburn instead. Then you will never have to open your enclosure to press a button, and you can tell the laser to start from the job origin instead of the laser home. Line up crosshairs, click frame, click laser, watch youtube until the job is complete.
Back in high school, I had designed a laser cutter based on one of those diode lasers as part of a engineering design competition. This appears to be missing some key safety features required for the laser class (IIRC).
Looks like the lid had two little flaps on the rear flap that are velcro and attach to the sides on the exterior to prevent it from being floppy like you showed in the video.
I'm enjoying the more even speaking pace in all of the videos lately. It's deliberate and less manic than a few weeks ago. Your enthusiasm still shines through especially in videos like this.
The fact that something like this is freely available to purchase for anyone who might not know what they are doing is somewhat terrifying - I know, I know, the usual american perspective to something like this is that it's peoples own fault if they fuck around with something hazardous but in general the amount of class 4 lasers freely available for purchase is insane. No disrespect to her, but if Yvonne had tried to use this thing on her own she'd likely be blind by now or would be suffering from other severe health issues. On that note, I do hope we get more content with Tynan in this style if he has the time to do it, this was one of the best short circuits you have ever made. Oh, and do be careful with the camera as well - you do use some rather expensive cameras after all and a laser like this can easily punch holes into the sensor as well. I have seen youtubes favorite laser and chemistry nutter styropyro kill one of his cameras with stray reflections from a high powered laser. (although admittedly that was a million watt pulse laser from china, not a cutter ^^)
Would love to hear your recommendation for a safe beginner laser. I've used an old omtech laser before, but looking for something for use at my home that is safe but not wildly expensive.
I've heard good things about Cricut desktop lasers. AIO system so those worries mentioned are lessened. I would still vent it out a window or run it in an open garage
I’m so glad LMG rates things at their crossed out prices, because even though the “sale” price is probably just the normal price, it keeps these companies honest somewhat.
One extra safety thing to point out with all that plywood they give you, be very careful when laser cutting plywood as low quality material with a lot of voids will be more prone to fires. Depending on the quality of what they sent it could be a fire hazard right from the get go.
I've seen things like this in store and the demo projects are inevitably plywood. There is a huge craft market in (overpriced or low quality) laser-cut plywood thingies for making cards and decorations. That's the sort of user these things get aimed at (which is worrying as heck)
this is so informative, thank you. I've been looking at this exact machine for a while and I think I'll pass for now, it seems like it needs a LOT of extras just to make it safe
Thank You! As a paper crafter I see so many crafters buying these because of the cost of the GlowForge. It looks like such a bad choice. Yes I'd love to create my embellishments and such, but safety is so much more important.
I appreciate the level of caution clearly evident in Tynan's approach to this. I see these lasers advertised all the time as something you can have in your living room with pets and children. This works by setting things on fire in a controlled manner. There is a lot of potential for mistakes and accidents where people can be seriously injured. So while I love the usual guns blazing approach Tynan has in other projects; I'm glad that the safety concerns were very clear in this one.
Really good review, I bought a different laser from xtool with enclosure xtool M1 and use those green glasses, will be switching out based on this video to different eye protection. The M1 itself does however use orange plastic unlike the Greek if the included eye protection here
I have a 3w blue laser, it will burn through a leaf in about 4 seconds and looks like an infinite lightsaber shooting into the air. 40w is over 13 times as strong. It is so powerful that even a mildly shiny object would reflect enough that it could cause permanent and instant loss of sight. a full reflection of a metal surface or a direct hit would instantly blind you and boil a pocket inside your eyeball. it only takes less than 0.1w of laser power to cause potentially permanent eye damage, they absolutely deserve serious respect and maximum safety
At my secondary school they had a laser cutter. One of those professional ones that was built around a metal enclosure, however looking back, I don't think it ever had a coloured look through, it was just clear.
It was most likely a CO2 laser, the windows for that type can be optically clear as they only need to block infrared radiation since that’s the wavelength of that type of laser.
This was very cool to watch. I have operated some large co2 lasers (4kw) as well as a fibre laser (2kw) and this is definitely the easies to use for the hobbyist. I agree with the enclosure argument, since more than a few watts makes for a very dangerous laser.
Usually, when Tynan is in front of the camera, shit can get serious very quickly haha He has some of the craziest ideas, but at the same time he knows his stuff like no one else. So if he's concerned about safety issue, you must listen to him.
i like tynan as a host on of tech type tools. he is a great fit for this. also funny guy. an he not missing anything important about the device which is great for someone like me that looking at one of these.
Bought one of these to test at work, as a hobbyist machine it could be pretty decent. For any semblance of production speeds it is unusable. Also need a well ventilated area and/or a vacuum to pull out fumes.

Can you please do a series with your engineering staff where they walk through purchasing and safety considerations for CnC's, Laser engravers, etchers, etc. Think "Etsy Safety" cause lets be honest, all of us have a side hustle now a days. I've used laser engraver before (low watt), and never considered half of the warnings he gave in this video.
The scariest thing about laser cutter/engravers systems generally and open-frame setups like this in particular is the fact that human vision has a lot of failsafes and compensation mechanisms built into it, and you have to do a _LOT_ of damage to your eyes before you actually begin to notice. It's not uncommon for people that work with lasers to have retinas the look like Swiss cheese but are still able to "see" more-or-less because their brains are editing out the blind spots.
To give an idea how dangerous a setup this really is: _The light from a 40W blue laser will almost instantly burn a hole in your retina just from the dot of laser light reflecting off a white wall._
One of these days I might build myself a laser cutter/engraver, but if I do it'll be a fully enclosed box with an optically shielded camera inside to use to see what it's doing, and safety interlocks galore so it won't kill my peepers.
I have a green laser pointer. Only 5mW. I still treat it like an eye hazard even though it's not powerful enough to be one because holy _crap_ it's bright to the eye.
Personally, I think the hysteria over laser cutters/engravers is over blown. I regularly work with a 2500 watt CO2 laser built by Cincinnati that has no issue cutting through 3/8" stainless. We've ran it for 15 years without an enclosure. Just don't be dumb and you'll be fine. It's the same with any tool you purchase. These small lasers aren't any more dangerous than an angle grinder. That's not to say an angle grinder isn't dangerous. I've personally seen an inch long metal wire sticking out of someone's eye, which had to be surgically removed, just because they forgot to put their glasses back on.
But go watch any review video of an angle grinder. You won't find the same hysteria.
People tend to handle self-preservation just fine on their own. Those that don't, will end up hurting themselves even with you telling them they need an enclosure.
@@NG-VQ37VHR _" Just don't be dumb and you'll be fine."_ Have you _talked_ to people lately? _"Dumb" is the norm._
These are being sold to Joe & Jane Sixpack, who more than likely don't have any actual experience working with eye-hazardous lasers. The threat profile here is that you can get eye damage and not even know it, and in a home or home-workshop environment you have secondary victims (e.g., family/pets) that can also get hurt without realizing it.
A hopefully-trained professional working with a commercial system that will almost certainly have integrated safeties (for example, I'd wager your CO2 system has interlocks to keep things like fingers out of the beam path) is a whole different animal than an amateur with a basic consumer system that has no real safeties to speak of aside from a little plastic shield around the diode's output end.
@@NG-VQ37VHR IMHO the main issue is that a laser seems fun and tinkery for everyone. Oh you can make nice wedding cards and wood puzzles. Theehee.
An Angle grinder is loud, noisy and scary because it is a rotating machine. Laser? Probably fine because it has a tinted glass and I have fancy googles.
Yes, both are dangerous. So is a kitchen knife. But you know a kitchen knife can be sharp as heck or stab your leg if it falls. Because you were taught properly. Laser? Oh it's just a 3D Printer or a cutting plotter with a laser instead of a knife. What could probably happen, right?
@@NG-VQ37VHR The hazard of cheap laser cutters like this is party psychological. An angle grinder is loud and scary, and spins really fast. It commands a certain level of respect even in many people who know nothing about it, and mechanical hazards are in general more relatable for most people. But high-powered lasers are something that most people have no concept about, and something that fits on your desk, relatively quiet, etc. does not put the fear into people nearly as much, and hazards like reflected light are not as obvious.
This video was super rad. I love the atmosphere and how educational it was. Good stuff!
This. I really enjoy this type of video. No forced jumping from talking point to talking point in the script or flashy "tiktok"-text on screen.
Very much this. I don't know how much of this was planned/shot/edited before or after the recent break, but... If this *is* representative of future video plans, my interest is piqued. The focus on safety, the pacing, and the tone of the whole thing really made it a nice watch.
Love the return to substance over style. No flashy editing, a healthy respect for the subject matter, lots of good information. A video you watch to actually learn something rather than just let play in the background.
This is probably my favorite ShortCircuits. Super informative, done by someone who seems well educated on the subject, and gives an honest take on the product.
Tynan is a great host.
Also its really great that there are seizure warnings, ive never noticed them before, are they new?
They've used them for a good while now! Very nice that they include them
BY FAR the best shortcircuit yet! absolutely loved this one.
He's such a great host and knows what he's talking about
as the head of the safety committee of my workspace. i thoroughly enjoyed this video. it's complete bliss for me.
I like him. He reminds me of my teacher teaching STEM in school. Some comedy, but non nonsense. 👍👍
I love the goofiness of LTT in general, but damn I would love to see more videos with Tynan that are just a tad bit more serious.. Imagine what this man could do with some of the watercooling projects 👏💪
Have you seen his Extreme Tech Upgrade? Man did copper watercooling and made an induction forge, absolute legend.
What a _calm_ Linus would look! And easy on the eyes and ears ☺️!!
Safety above all else. Would like to see other examples of what the laser can do.
Thank you for the video!
Tynan and Dan are always so informative in a nice soothing way
Yeah Dad energy lol
Really well done on this Tynan! I really love the conclusion and the focus on safety.
Great to see a REAL presentation with respect for safety.
we use Lasers on my Workplace and i cant stress enough how bad of an idea it is, to use them without an enclosure.
id go further and say that the Enclosure they provide is way to cheap to trust it 100%.
if id need to have a Laser at home, id be using Webcams as "Windows" and would built the Enclosure without any physical windows.
Also the Enclosure shoud have a Detection if the Panel is open. and if it is, it should cut power to the LaserHead
And requiring to press a button INSIDE of the Enclosure, so you have to start the Laser without the Enclosure closed is Highly Dangerous and Dumb...
Nice ShortCircuit and all of your concerns are 100% the same as mine
I agree that these “cheap” lasers just aren’t worth it in the end and are shockingly dangerous to the end user. Ppl just want to be cheap and ignore the safety aspects of these things in order achieve said cheapness.
The level of electronics/electrical skill required to re-wire that button to the outside of the enclosure is pretty low, but again with the 'why is this even sold this way?'
@@mycosys youre right. its not RocketScience to move a Button.
BUT, ignoring the fact it could be bought without an enclosure, there SHOULD be a Header/Connector for a button wich should be integrated in the enclosure. yeah 200$ is way to cheap for an enclosure which meets all Safety Criteria like i said before. but if somebody buys one for safety reasons, there should be an integrated 10ct Button with a long enough cable to just plug in.
i hate it when Manufacturers cheap out on cent-parts making the end product way more unsafe due to "supposedly safety" where no safety is. to loose sight it doenst need minutes, it needs fractions of a second.
imaginge someone wants to etch metal, the laserbeam reflect off the surface in the first second while the enclosure is still open to start the process...
yeah its maybe dark thoughts but theres a Reason LaserEngraver/-Cutters need to match so many certifications in the Industry
4:15 damn, wasn't expecting you guys to be firing M1's in this vid. Bringing back the flashbacks.
Tynan is easily one of the best presenters at Linus Media since Luke. None of the overly hyped cringy reactions. No silliness for silliness' sake. Just good presentation, information and real, human interaction. 10/10
I actually liked that silliness. If I want serious stuff, I would read engineering dissertations.
I'll let my plebeian self out.
@@DizzyBusy I don't mind some silliness in balanced amounts, but of late it has been more and more short attention-span grabbing random fluff punctuated by shrill, ear-bleeding squeals, crashes bangs and forced exclamations (that the editors don't level out properly, thus making them literally painful to listen to when they peak)
Yeah I'm an elder millennial, so a lot of it is just me being old and not vibing with the kids' love for hyper-reactions. I liked the Linus/Luke balance back in the day, and I liked how at first they seemed to keep that with new presenters, before it became balls-to-the-wall content for content's sake. I hope that that will return now that they have had their recent introspection.
One of the greatest shortcircuit videos. Very detailed about pros and cons (instead of YOLO it).
This video made me realize that I’ve been letting LMG videos play in the background. It feels like it’s been a while since there was a video that was actually worth actively giving my attention to.
Really glad we are going back to quality videos.
IKR? I am really loving the new quality video's like this, no more of that cheap garbage that they were spitting out just to maintain an unrealistic 25 video quantity every week BS. This is the quality we deserve if they want to keep us as viewers. I really loved this segment, and Tynan deserves to be in more video's IMHO!
Loved the follow up, and love the breakdown on how unsafe it is
Serious without being dry and very relaxing yet informative. Well done Tynan and team!
Got sick and tired of all the goofing around from so many others.
I don’t mind some goofing but so many reviews were just nonchalant and seemed more like a high school project than a review.
So far Tynan and Dan are absolutely excellent choices as hosts and the script has quality to it.
Keep it up LMG 👏
This company is either very confident in its users' ability to perform their due diligence about safety precautions, or they are very confident in their lawyers.
I like Tynan as a host, his speech tempo is just the right speed and very easy to listen to.
Oh look Linus has a safety conscious version of himself!
They tested the laser on Linus pre-recording and sculpted him into Tynan
Achievement get: Have a comment featured on an LMG channel!
Seriously though, thank you for producing this in depth follow up hosted by someone who knows what they are talking about. I am not faulting Linus, Yvonne, or those who helped put together the video, cheap laser marketing preys on people who want the tech without knowing the important safety considerations; I hope they built an enclosure or replaced that machine.
The conclusions here are solid: these types of unenclosed, high powered lasers are simply not safe, and really should not be used by people who don't know what they are doing. I like that this xTool system is trying to bring a safer laser system to a lower price point, which is definitely better than the super cheap extruded aluminum AliExpress kits, but it should all be sold as one kit. I still fear someone who doesn't know better thinking they dont need the extra safety equipment and hurting themselves. And the people who do know better are probably looking for a more professional laser system as you alluded to in your video.. I am glad that the lasers I work with are fully enclosed with professional grade fume extraction.
We only have one set of eyes people, stay safe!
For leather, make sure it is vegitanned/naturally tanned. If the leather was quick tanned with chromium, it could be problematic for laser cutting. pretty sure its mainly nasty off gassing but, the laser and the chromium don't interact well.
for my open frame laser i built a full metal enclosure for it with a window rated for the wavelength of the laser and outside air extraction
A 40W laser for hobbyist, with questionable safety glasses and an optional enclosure. Very dangerous. This thing should have a fixed, interlocked enclosure.
Also, whoever gave LMG the notes on how to properly do Seizure warnings! Thank you! You are a hero.
This should be it’s own category like
lo fi this should be called lo fi asmr review so calm
Okay this was a great video. I learned a lot and I appreciate the focus on safety because I have a laser cutter on order and I learned things I didn't know I needed to know
Give this host and writer a gold star and a gold xbox controller
Laser cutters can be amazing tools as long as the risks are understood and managed! If you are ever unsure it’s worth doing a bit more research or taking an extra precaution
I have no use for a laser cutter, but I really appreciate learning about it from someone who actually knows what they're doing/talking about
Big note on the "real leather" this is incorrectly phrased. You want to make sure it is VEGETABLE tanned and NOT Chrome tanned as this will release chromium gas which is toxic.
I'm not a longtime viewer and I can appreciate the fast pace and goof-level of LTT as a form
Of entertainment but this video is a really good example of the kind of video I appreciate most! People who are majorly into DIY and Maker culture telling me about their particular interest!
Ok, this is probably the best laser video I've watched so far. This with Maker Muse's video on what you should and shouldn't use on a laser make for a great pair. Thank you for making an in depth video on how to use a laser properly. It is interesting that with all of those features, the Glowforge ends up being a better value and with a better enclosure. Not sure about their fire suppression system though. I don't know if this video has been in the works for a while, but I'm glad it's out now after the controversy. This is a great direction to go for discussing potentially very dangerous tools that aren't obviously dangerous to some people (versus something like a table saw where anyone knows to stay away from it).
I’d have to disagree. I felt like he just opened the box one day and decided to do the video. It looks almost like no research was done and he did not have a good grasp of understanding the basics of the machine. For instance positioning is 101 and spelled out in the software when you go to process it. There was nothing in depth to this. Safety is important and I’d never fault anyone to go above and beyond what they need, but the shields and glasses are rated for safe use with these. They’re made for reflective or stray beams. If you have someone pointing the laser directly at your eyes then there’s something else wrong.
I wouldn't even put in a window in my enclosure but use a cheap camera sensor with a cheap lens to the outside with a screen on ( and good thing about the sensor and lens being cheap is that if it break/die from some odd reason its easy to replace) and since it's a camera and a screen there is absolutely no way that all the bad rays gets through to my eyes
This guy needs to host more videos!!
As "monotone" as this is, I absolutely love this video. Its someone that understands the tech and the safety, and I wouldn't be surprised if Tynan insisted that the camera op and anyone else nearby wears the safety goggles
That’s a great laser. I use it daily as well as many other lasers depending on what i am working on. I do hate the lasers without enclosures. Do prefer Co2 or Fiber.
Linus 2.0 now with 50% less controversy
That pricing is mental... You can get a fully enclosed CO2 laser for that!
Yet ppl will buy this dumb thing for some reason.
@@chadhowell1328 simply because of cheap entry point not realizing how much more equipment they still need but will justify not having
@@DracolegacyOfficial yep! The more expensive models are more expensive for a reason. Lasers are one place I wouldn’t cheap out
@@DracolegacyOfficial This is meant for China or the third world in general where we don't care/obsess about safety. The little shield surrounding the laser is meant to protect against direct reflections, and combined with the glasses, that's considered more than enough.
@@rexsceleratorum1632 Ah yes, the third world, where human lifes are worthless, am I right?
I have a 5W D1 from xtool and the first thing any owner should do is ditch the awful XCS software and use Lightburn instead. Then you will never have to open your enclosure to press a button, and you can tell the laser to start from the job origin instead of the laser home. Line up crosshairs, click frame, click laser, watch youtube until the job is complete.
I love the blowtorch to light a candle, makes you question why he didn't just use a lighter
Back in high school, I had designed a laser cutter based on one of those diode lasers as part of a engineering design competition. This appears to be missing some key safety features required for the laser class (IIRC).
Looks like the lid had two little flaps on the rear flap that are velcro and attach to the sides on the exterior to prevent it from being floppy like you showed in the video.
Tynan: don't buy this dangerous laser product.
Alan Pan: wow, I made a laser fly swatter with aggressive lack of safety features!
I see Yvonne has finally upgraded!
I'm enjoying the more even speaking pace in all of the videos lately. It's deliberate and less manic than a few weeks ago. Your enthusiasm still shines through especially in videos like this.
Thanks for taking your time and saying that you did not do the ideal conditions for the lazer. Information given with some recommendations.
Looks like Linus, is calm and collected like Dan
We need more Tynan please, he's a brilliant host!
I really like that he warns not to buy this product. These seems to be for a market where human live (and eye-sight) is expendable.
Why did you, apparently, make this comment before even watching the video?
That would be the third world in general
@@Ragnorok64 Because TH-cam's displayed times are broken.
once again saying thank you for the audio cues with your seizure warnings, it's extremely helpful 🙏
The fact that something like this is freely available to purchase for anyone who might not know what they are doing is somewhat terrifying - I know, I know, the usual american perspective to something like this is that it's peoples own fault if they fuck around with something hazardous but in general the amount of class 4 lasers freely available for purchase is insane. No disrespect to her, but if Yvonne had tried to use this thing on her own she'd likely be blind by now or would be suffering from other severe health issues.
On that note, I do hope we get more content with Tynan in this style if he has the time to do it, this was one of the best short circuits you have ever made.
Oh, and do be careful with the camera as well - you do use some rather expensive cameras after all and a laser like this can easily punch holes into the sensor as well. I have seen youtubes favorite laser and chemistry nutter styropyro kill one of his cameras with stray reflections from a high powered laser. (although admittedly that was a million watt pulse laser from china, not a cutter ^^)
Great video that taught me a lot. I was hanging on every word. I'm not into every single video Short Circuit puts out, but this one was worth my time.
This was a very informative and chill vid. Loved it.
No screaming Linus is always welcome
Great video. Loved the no nonsense segue too. Tynan just needs to work on his thumbnail-surprise face
Yeah I agree 😂 tis a work in progress
Linus had a make over
Would love to hear your recommendation for a safe beginner laser. I've used an old omtech laser before, but looking for something for use at my home that is safe but not wildly expensive.
I've heard good things about Cricut desktop lasers. AIO system so those worries mentioned are lessened. I would still vent it out a window or run it in an open garage
@@da3dsoul thanks! Definitely a good option, though I'm not a fan of their proprietary software.
@@tellingyoustories yeah it's pretty common for maker equipment to either be very DIY (not a simple package) or maliciously proprietary
I’m so glad LMG rates things at their crossed out prices, because even though the “sale” price is probably just the normal price, it keeps these companies honest somewhat.
Great video and Solidworks appears to me to be almost the perfect sponsor for this kind of video.
One extra safety thing to point out with all that plywood they give you, be very careful when laser cutting plywood as low quality material with a lot of voids will be more prone to fires. Depending on the quality of what they sent it could be a fire hazard right from the get go.
I've seen things like this in store and the demo projects are inevitably plywood. There is a huge craft market in (overpriced or low quality) laser-cut plywood thingies for making cards and decorations. That's the sort of user these things get aimed at (which is worrying as heck)
this is so informative, thank you. I've been looking at this exact machine for a while and I think I'll pass for now, it seems like it needs a LOT of extras just to make it safe
Most informative vid I’ve seen for a while. Really feel safety was important AND he was being honest and sincere. 10/10
hell yes, give me more Tynan videos
short circuit video that aint so short? aight thats cool also heyo tynan! glad to have you on camera again
Linus bigger brother Linos
Thank You! As a paper crafter I see so many crafters buying these because of the cost of the GlowForge. It looks like such a bad choice. Yes I'd love to create my embellishments and such, but safety is so much more important.
love the honesty and the repeated safety warnings
Additionally regarding the leather, be aware of the tannage and treatments of the leather. Oil tanned hides will often just burn
I appreciate the level of caution clearly evident in Tynan's approach to this. I see these lasers advertised all the time as something you can have in your living room with pets and children. This works by setting things on fire in a controlled manner. There is a lot of potential for mistakes and accidents where people can be seriously injured. So while I love the usual guns blazing approach Tynan has in other projects; I'm glad that the safety concerns were very clear in this one.
Tynan is chill and some how not boring like Steve from GN
actually confused me for a few moments when I wasn't looking too closely at the screen because that was not the voice I was expecting from linus
Awesome vid. Very informative.
Tynan should do more vids in the future!
Really good review, I bought a different laser from xtool with enclosure xtool M1 and use those green glasses, will be switching out based on this video to different eye protection.
The M1 itself does however use orange plastic unlike the Greek if the included eye protection here
I have a 3w blue laser, it will burn through a leaf in about 4 seconds and looks like an infinite lightsaber shooting into the air. 40w is over 13 times as strong. It is so powerful that even a mildly shiny object would reflect enough that it could cause permanent and instant loss of sight. a full reflection of a metal surface or a direct hit would instantly blind you and boil a pocket inside your eyeball.
it only takes less than 0.1w of laser power to cause potentially permanent eye damage, they absolutely deserve serious respect and maximum safety
Me for years: i need a laser tool for my shop
me after watching this video: oh its actually dangerous, maybe i dont need one
There are some that can be safer when used properly just make sure you do your homework and are aware of what risks exist!
Excellent to see proper respect for the tools. Very info heavy and the future fore shortcircuit i hope.
video starts at 13:45
At my secondary school they had a laser cutter. One of those professional ones that was built around a metal enclosure, however looking back, I don't think it ever had a coloured look through, it was just clear.
It was most likely a CO2 laser, the windows for that type can be optically clear as they only need to block infrared radiation since that’s the wavelength of that type of laser.
This was very cool to watch. I have operated some large co2 lasers (4kw) as well as a fibre laser (2kw) and this is definitely the easies to use for the hobbyist. I agree with the enclosure argument, since more than a few watts makes for a very dangerous laser.
Really like Tynan. He's so easy to watch!
17:35, He really looked like Linus in this frame holy #?!@.
Usually, when Tynan is in front of the camera, shit can get serious very quickly haha
He has some of the craziest ideas, but at the same time he knows his stuff like no one else. So if he's concerned about safety issue, you must listen to him.
very new and informative format, NICE!!!
LMG?
Amazing.
Seriously
Entertaining -
Really!
i like tynan as a host on of tech type tools. he is a great fit for this. also funny guy. an he not missing anything important about the device which is great for someone like me that looking at one of these.
Bought one of these to test at work, as a hobbyist machine it could be pretty decent. For any semblance of production speeds it is unusable. Also need a well ventilated area and/or a vacuum to pull out fumes.
Loved this super informational and safety conscious Vid!
