Either way, what I found was that the first pass engraves through the top layer, but leaves some colored residue behind. The second pass cleans it up since it doesn’t have to engrave through the colored layer and the residue is so fine.

Finally got a chance to check this out on the glowforge.
For me:
- I peel the masking material off before running it through
- make sure you have the ultra thin second color stuff on the side with the laser.
- engrave: i am using manual cut, thickness 0.05", 1000 speed, 20 power
- cut is manual of thickness 0.05", 350 speed, full power
this got decent results for me.
notes:
a) if i move slower than 350 for cuts then the material gets melty, stinky, and leaves a sticky residue on the bottom side of the print.
b) If doing patterns I ran a second pass on engraves. and I tended to pick “patterns” vs “dots” because I liked the effect for the couple things I played with. If just doing black and white with no patterns/halftoning that will be done by the software then I just needed one pass and was perfectly happy.
