I’m new to laser engraving, just installed one on my 4’x4’ CNC router table.
Anyways… The laser module is a cheap Chinese 5.5 watt blue diode.
I’m having fun using it but notice a big difference between engraving MDF and Ash. MDF is consistent and the Ash because of the grain density and texture there is no consistency in the results. My question is for the Ash if I want the engraving darker, is it best to slow down the travel speed or up the laser power or both? For lines I’m running 1200mm/minute at 85% power. For fill I’m running 1400mm/minute at 75%
