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!

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.

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

Only made it 3 minutes into your video before getting my laser right. Thank you your the most helpful YouTube professor out there

[finalaccuracy]

Can't wait for the USB microscope video

[darthstewie]

Keep up the good work. I'm glad I found this channel, I've learned a lot about my laser so far.

[NickSpirov]

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.

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.

[jimginnyohio]

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?

[wkduff]

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.

[DJapan]

Mine is the 20watt so you don't turn the lens anymore, you just slide the whole laser module up and down.

[wynetteterblanche]

Thank you!!! This helped me so much!!!

[SlingShotNinja]

Thank you. I didn't know I can move the lens up or down.

[KristopherFAudio]

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.

[DennisCrawfordJr]

Great videos love the channel. What are you tuning on the bottom of the Lazer?

[ParaglidingManiac]

I don't have a MOVE tab in Lightburn. Is there a way to enable it?

[mallorikerr]

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.

[DavidJones-dset]

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.

[spinwurkzmotoryclesuraloft]

Thanks man. I've watch a few of your vids. Very helpful 👌

[dubamakersworkshop]

Thank you so much for this. Super laser newb and this was perfect for my level 🙌🏼

[pythonmediaworks]

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.
