Hello, I have a chinese 150W CO2 laser. To engrave glass I use 400 mm/s speed and 40% power. I tried with interval 0.1 mm and 0.06 mm.
After engraving the graphic has particles of glass stuck to it which need to be removed manually. Is there some way to solve this?

I assume you have a DC laser. This type of lasers is used primarily for cutting, not so much for engraving. Can you post some pictures of the problem and the machine?

Try lower power faster speed. 150 is really to much power for engraving. Most people have 60 to 80 watts for engraving. The high power tubes hard hard to dial down for a decent engraving.Glass needs lower pwr faster spd
