I've generated in AI my own imagination of Darth Moul, I've prepared in Jarvis style as na 14 inches squared picture lasered on coated canvas on black. It is good theme on the Halloween party as an futuristic decoration.
You have to choose canvas connected with your work area available.
You have to paint canvas with white firstly and after when it'll be dry cover it by black paint (I used available shop spray paints). Tip - prepare 2-3 canvas for tests as well.
You have to prepare one canvas (maybe smaller) extra to make test with your equipment, because every paints are different, you have to test with your laser how it'll work. You have to choose settings ideally do not burn paints out.
Set your setting (tested), on you machine, double check the thickness of your canvas and start burning.
