I tried to engrave a photo on a glass. When I did that I realized that some small particles of glass are pealing off.
I did some research on internet and find out that I should cool the glass surface by putting a wet newspaper on the top where I will engrave a picture.
I tried that but the paper got burned into the glass and now it looks all crappy.
Is any of you guys have same problem? I did contact Baggy from JQLaser and she told me to increase the speed of engraving and lower the power of laser. I'm not sure if that will help.
Also is it normal that it took 50min. to engrave a small picture of 3" X 4" in size?
