Yeah! Be sure and check that thread out as there was a lot of good info there :)

Here are some I did on a 100W laser as Christmas presents too :)

My thought was to keep it manual and just turn the knob to lift and lower it. Mostly thinking about using it to raise the part for multiple passes.

Your not supposed to scrub around with a Super Capacitor then touch the cat! That ends with,,, "we used to have a cat!!!!

I cannot confirm nor deny that this did or didn't have anything to do with the cat's untimely departure. :)

Esd straps are strongly recommended when working with bare laser diodes.

Here are some greyscale images done on wood and slate with T2L.
I don't have the settings with me so I can't give you those but they should be here on the forum somewhere.

.5mm is what I started with as well and quickly changed to .1mm. Others have stated they use .15mm and that worked well for them which is why I mentioned it.

Time is dependent mostly on feed rate and that you will adjust based on how dark you want the engraving  to be.

If you end up using T2L, you will have the ability to use the dithered mode to do images which will give you a more greyscale look. This should work well with non-TTL laser modules.

I don't know about 10% of all :) but your post did prompt me to move this from my TODO list to my IN-PROGRESS list and the link was a big help too, so I'll definitely have to hook you up :)

I'm taking my STMICRO boards and little displays with me to work on just that :) I have a few product projects going with me and hopefully will have some cool stuff for sale when I get back, this being one.

LW3 has a setting for beam width, set this between .1 and .15. This is similar to T2L's resolution setting.

I'd have to say that worked pretty well :) I did a quick calibration with my 2W laser diode and the 30W LPM I purchased from ebay. Next I grabbed my TEC that I painted black on one side and added a heatsink on the other and then I hooked up my multimeter to it and fired the 2W laser at it. From this I got that my setup was 12.73 mW per mV. I grabbed some laser pointers I picked up from Banggood.com and tested them. The numbers I got were pretty close to what other people on Youtube were getting.

I added some more binder to the paint but I need to see how good the adhesion is with this change. The previous coat of paint I put on the TEC wiped off with a paper towel so, not good. I'll check the adhesion once it has had a good time to dry.

Here is a picture of the paint and the setup I threw together.
