Black is a non-reflective surface therefore you get a much sharper image.

Great Video Phil
I can’t wait to get home and back into the X-carve addiction… a Laser is Definitely on the list, But since it’s been 6 months since I put the machine into storage mode, I’m sure I’ll have to work out some issues and re-calibrate everything before I can even think about getting a laser and putting it into operation…
then there’s the whole software side… I’m going to have to get serious about learning G-code and sending projects with UGCS or PICSender or…or …or…
ANYWAY… only a few more weeks and I can do more than just read the forum and add to the “design” folder on my laptop. so many projects waiting to be carved…

Which software do you use for generate gcode for laser engrave?
There is a technique for focusing I used when running an industrial machine.
Thermal paper.
The laser will burn it and you can see the dot shape and clarity.
Just put it on low power and fire a pulse.
You should see a small dot and its shape and edge sharpness will be visible.
You can get thermal paper from any office store / eBay etc.
Used receipts work too.
