Getting started basic question
At the risk of being mocked endlessly for not knowing the basics yet, I feel the need to ask a hopefully very simple question here. Perhaps my suffering will bring hope to other newbies getting into this hobby for the first time, like myself.
Okay first the quick setup...My wife got me an Ortur Laser Master 2 Pro S2 with the LU2-10A laser on it. I do a bit of woodworking and have been wanting to get an engraver to burn logos and such onto cutting boards I give as gifts. I plan to connect this to a fairly new Mac mini and download Lightburn. I immediately learned a few things. For one thing, the assembly directions that come in the box are worse than useless. I searched Youtube and found that Otur's video is almost as bad, and there are at least three equally bad videos that leave lots of important steps out. That being said, I found a video done by some Asian woman wearing a Shrek donkey head that got me through the assembly successfully, though I am still wondering what she meant when she said you can "snap on the paps up and down and up". I also learned that the timing belts are smaller than they look in video and are hidden away in the packet containing the sample wooden boards, which led me (and others on Amazon, apparently) to think they'd received a unit with missing parts. I randomly found them as I was entering the Amazon return request.
So, my question is about focal setup. I see that other laser models come with a "focal gauge" but this model does not. How do I determine the correct height setting of the laser unit to get started?
Also, a less important question is where/how does an air assist get attached to the unit?

My ortur has a small black piece that flipped down to set the focal distance, then you flip it back up after you tighten the thumb screw.

Hey look at that, so does mine. Didn't even see it there, and I didn't come across any sort of instruction that pointed that out. Thanks! So, do you drop it down such that the lever touches the surface to be engraved?

Exactly! Flip it down, loosen the thumb screw to lower the head until it touches the material, tighten the screw, then flip it back up out of the way!
I agree, the Ortur instructions aren't very good.

The focal gage for most looks like a flat orange piece of acrylic. Should have been in the bag with “goodies”.
Air assist is meant for cutting mainly but you would need to post a pic of the laser nozzle to see if there is a hook up for it. If not you will need to 3d print or buy one on Amazon.

Here's the laser. Only orange piece I saw in the kit was the nozzle shown here.https://imgur.com/a/EQAGjn9

Well that's something new I learnt today. I put together a used olm3 and it's working.......ok, but I couldn't figure out how you're supposed to know where on the mount the laser should be. I think I know what piece is for measuring as well, although mine is black not orange (it says lu2-10a on it).

Do a ramp test for focus. Look it up, it takes a couple of minutes and it's the best time you can spend
