Black marble photo engrave.....very nice results....beware though...its very soft use high as speed...low power.

@Scott_Thorne sweet. I appreciate it. So we both know the wors of the job. Cool.

Scott very good work. I am starting out trying granite with some crappy results. I do not have the ma meter so I got no idea what to set my power at. I have read and tried 85 % but that seems way to high.

@Richard_Gallatin . …I run min…at 10% and my max at 45% with a speed of 300 mm/s…thanks for the comment by the way.
