Thanks Jim!
I haven't really tried engraving wood but I'd guess it would burn easily but it would be difficult to control the depth since the wood grain all reacts differently to the beam. Certainly doing a logo or some 2D type insignia would be a piece of cake since the black/burnt pit wouldn't really need to be a constant depth, just a form of etching with a blackish area.
LBD has done etching to depth with a CO2 laser (more $$) in MDF. The consistent material makes it easy compared to wood with grain. He then will fill it flush with colored filler to get a great "solid" color that is beyond just a painted monochrome pattern.
A diode laser can do that, just needs more time to blast a pit deal enough.
Forget any 3D type carvings.
