If you're talking about mother of pearl inlays, I've been told that MOP doesn't react well to the laser. I took some blanks to a trophy engraver who has a powerful laser system, and he hasn't had much luck cutting the MOP. He's dinking around a lot with the power settings. Maybe he'll find a way, but I'm not sure it's going to be THE answer.
I think a CNC is the way to go, it's the way a lot of MOP is cut these days. I'm sure a way will be found to do it on the CW machine someday. Getting the software adapted to work with a smaller bit would be a useful item.
