Focusing a Diode Laser Quickly - Featuring the Ortur Laser Master 2

- Today we go through focusing a diode laser quickly. This video is featuring the Ortur Lased Master 2 as that is the laser I have. This would be the same in any adjustable laser, and you want to make sure your focal length (distance between the laser head and the material) is correct before focusing.
**** I know there are many ways to do this, and people use different powers and colored paper, etc. This is just the way I do it when I am in a hurry and don't have my USB Microscope ready. It's important to get the laser as focused as you possible can to get the best results out of it.
***** Please remember to use your laser safety glasses when doing this at ANY Power!

Nice video, however your focus is one paper thickness above the surface of the item. Now you take the paper and put it BENEATH the item, it will rise just one paper thickness up and then you have perfect focus.
hi! i just got my ortur 20w and i´m trying to engave on acrylic but goes through the sheet and just burn the other side what should i do :(
How do I focus my laser if I don't have a dial to focus on my Ortur using grbl?
Where is the usb microscope how to video like you said ?
I recently purchased the Ortur LM1, a 15w version. Will the focal point be the same as the LM2?
I have an Ortur LU 1-3 laser and wanted to know if you have any suggestions for focusing it. The focus knob is pretty tight to turn and takes some effort. Ortur said to put the laser from 30-35mm away from the object and focus until the smallest circle is obtained. I did that and burnt something on my tumbler and it didn't do as good as being about 60mm away and left the focus alone. Any help would be appreciated.
Can't wait for the USB microscope video
Great info. However, my biggest questions are: How do I know the correct focal length for my laser? Also, how do we do this with a non-G8 lens where we have a line instead of a dot?
For Ortur it is below. And with the line you do it the same way. Just as small as you can get it.
7W 75MM
15W 55mm
20w 35mm
Aside from all the other great things about your channel, one thing that just makes me all warm and fuzzy inside is the fact that you have a short and concise intro.
Mine is the 20watt so you don't turn the lens anymore, you just slide the whole laser module up and down.
Thanks! I just set up my 20W today and couldn't find an adjustment know anywhere. I was wondering what was going on. Good to know the 20W does not have a knob to begin with.
Just got the LM2 20W myself and have been binging your content.
To all interested: The new 20Ws (and 15Ws maybe according to the card I received with mine last month) have a fixed lens and z-axis adjustment. They ship with an aluminum focal length cylinder (just something to ensure your laser is the proper height above your surface). You can still fine focus slightly by pulling down on the lens though so this still applies a bit.
Also FYI: you cannot change the lens in the newest versions so don't do like I did and buy a G8 before receiving the newest version :-P
What is he talking about? My Ortur 2 does NOT have an adjusting knob at the bottom of the laser. What is he adjusting?
Hi
I wonder if you could give me some advice please, I have a Ortor master 2, setting up my laser beam, I have a thin outer circle, with a dot, in the middle, the dot in the middle does change in size, when I adjust the height, but the thin circle around the Dot stays the same is this normal, many thanks
Neil,
I don't have a MOVE tab in Lightburn. Is there a way to enable it?
Great video thank you. Could you achieve 0.1 mm line engraving with this?
as a suggestion, you should put this video as a link in all your videos, this would solve a lot of individuals issues not knowing why we cannot burn on canvas.
I had no idea we had to do this.
Good idea! I'll look at doing that! Hope the video helped, and are rocking the laser now!
Hi Jim
In your video on focusing a diode laser I notice you were able to turn the dialing knob with one finger.
On my Ortur 15w that knob is so tight I'm not able to turn it without using pliers to grip it!!! Surely that can't be right?
Any ideas how I can free it up ?
I'm super new to lasers so this may be really stupid but....how do you find the focal length for the laser to set the height? I don't see anything listed on mine - Creality Falcon 10W - so is there a way to know?
Not a dumb question! Looks like it came with a focusing tool. They call it 3 step focusing. I saw the picture of it here: www.creality.com/products/cr-laser-falcon-laser-engraver-10w
@@TheEdgeofTech Yes, I did get that with mine also but it is only good for those certain sizes. If I want to engrave on a board that is 3/4 inches thick I don't think that step would work as the sizes listed on it are only a few MM. That is where I am confused or is it basically I should only use materials up to that max listed on the step guide? I hope I explained taht good enough. I really suck at explaining things LOL
@@StumblingBumblingIdiot I'll.have to look at it closer, but normally this would go on top of the material you wanted to engrave, no matter what size.
@@TheEdgeofTech oh ok. I thought the steps were for the material thickness. I will re-read the manual again!!!!!! Thanx!
Keep up the good work. I'm glad I found this channel, I've learned a lot about my laser so far.
Thanks for watching! I am glad the videos help!
There is no focus knob on my ortur laser master 2 S2, so i need some instructions to focus this, as still i was not able to get a focus.
how can i fined my focus leanth using a VG-L3 30x40
Newbie here. I just got the Atomstack X7 pro and have a lot to learn! I subbed and hope I can pick up on some tips to get up and running.
Thank you so much for this. Super laser newb and this was perfect for my level 🙌🏼
does he ever answer the questions or I am missing something?
I try to answer as many as I can. On older videos It gets harder and harder because there are so many new comments. Did you have a question specifically?
@@TheEdgeofTech my apology that bad comment on my part. Very sorry. I am using Ver: 1.3.01 of light burn. How did you get fill+cut on your tool path? My Laser is S9
my laser will not turn. Even if I grab it with pliers.
Thank you for all the videos. Very informative. How did you get the G8 lens to the right distance and how did you get it tight? Any help/advise would be appreciated.
Great Video. I wonder if you can answer a question for me. will the Ortur Laser master 2 cut a series of small holes in cardboard .75 of a mm. My wife does bobbin lace and this would be great for doing pricking for lace patterns. hope you can help thanks.
That's a great question! I'm not sure if it would or be that small. I guess I've never measured a whole lol But I would think it's possible depending on the size
Which g8 lens do you recommend and how did you replace it on your lm2?
What distance should the material you want to burn be from the lens? I have the same machine and am finding it hard to find the info. As far as I can remember there was no gauge or anything.
How do you focus the laser for a LU1-4 ?
Hope it’s ok to ask a question-- I have an ortur laser master 2-can’t get it to burn - i think my problem is the laser won’t focus- I’ve done the distance thing but still no luck. Do u have any suggestions?
Thanks for this video. I have bought a G8 Focus Lens but in order to get a tiny line, I need to turn (loosen) the knob so much that it is barely attached to the module. It is so loose that I can move the "dot" on the material by 3cms by simply touching the knob.
You say that with your G8 Lens, you leave a 72mm clearance between the module's sink and the material. But what OLM2 module are you using? 15W? 20W?
Hello. Great videos and great chanel. Thanks. I have 1 question.
I have Atomstack A5 20w. How i can focuse that laser. It have a nothing for focusing 😕
Mine came with a aluminon block is that for the height?
so did mine, from what i understand, its called a fixed laser. Just put that block between the laser and what your engraving and tighten the screw on the side.
I have a Genmitsu CNC 3018-PRO unit and my laser beam is a very small rectangle not round is this normal ?
great vid, BUT i have 1 question that is a hot topic. capped or uncapped laser diode. Lately it seems that Ortur ( like mine LM2 15 Watt) has a diode that is NOT capped with a gasfilled lens. This means that the life of the diode shortens very much. Ive issued a ticket to Ortur, but they say there is a 1 year waranty and when it is broken , i will get a new one. But nothing about un/capped diode. Maybe you ccan give answer on that. In a couple of FB-groups there are lots of discusion about.. Greetzz Fonz
Thanks man. I've watch a few of your vids. Very helpful 👌
What about the focus block (rod) that comes with the unit? Is it the exact correct focal length? Because I seem to get better focus a bit closer and I get a very tiny spot dialed in and it is always a smaller gap than the rod put it at.
Thank you for the video! Your videos are very well made and easy to understand. Would you be able to do a video on how you installed your G8 leans? Where did you buy your G8 Lens? I didn't see a link for the G8 lens! I just got the ortur laser master 2 20w and trying to figure out how to use it.
Thank you so much. I just started with the totem two trees 2.5 engraver and trying to figure out all the necessary settings has been a challenge.
How on earth can you turn the focus wheel with one finger ? On.my 15w it barely turns even when i use a finger and thumb. The only time i can turn it easily is if i fit a printed wheel to it and even then after a nbr of turns that wheel begins to slip.
Hi. nice viveos thanks! Do you already have the video with the usb microscope?? regards
hi Jim, when you cant see the fire button in lightburn try double clicking at the top of your web page it works for me cheers.
Great videos love the channel. What are you tuning on the bottom of the Lazer?
Hey Jim - Where is the promised USB Microscope video?
I just did a video on how to install it last week! ;)
@@TheEdgeofTech I saw - but, an Endoscope is not a USB Microscope.
I don't see the link for the USB microscope
I put it in the description now, but here you go! amzn.to/3a1K7Dt
Thank you. I didn't know I can move the lens up or down.
Only made it 3 minutes into your video before getting my laser right. Thank you your the most helpful TH-cam professor out there
Fire + Frame does not work! What to do? how to set it up?
Hi there, my ortur is engraving well on walnut, but is having issues on maple and cherry. Any ideas why this might be happening? Thanks in advance!
Different hardness between the woods. You need to experiment on scrap for each wood type before doing your burn
How do you change the lense to the one you have? Link for that?
Thanks
thanks for the awesome video
Thanks for the education!
USB microscope. Great idea.
Thank you!!! This helped me so much!!!
Looking for link to usb microscope??
I put it in the description now, but here you go! amzn.to/3a1K7Dt
@@TheEdgeofTech THank you so much. Trying to get mine figured out. Never thought of the microscope
Hi I don’t have anything that can turn
Great video! Love all your content! Thanks!
I have tried my best to focus mine and it still will not cut or engrave anything.
Make the point as small as possible By turning the ring If its not still doing nothing then I think you've got a dammange laser
@@davidwhitt3299 I think I do it lights up but no cutting. It is new and I have the seller sending me another, it is only 1/2 watt. I ordered a 3 watt also. thanks for the reply!
@@saintcharlesdesigngroup4419 im un sure is only do 7w 15w 20w
Amazing
The new ones is all fix focus lot easy how
did you get an height block with yours?
@@174859607 Yeah the Metal block just under the lasser to set it and ready to burn
I have the new one also it slides up and down right so when you put it on the plate which hole do you use?
@@174859607 Let's see you have at a tile put the metal bock on the tile and then low it to the metal block and the Len hit the block And it Screw the laser to whatever hole it's come to
@@davidwhitt3299 thank you my friend
