I have lots of experience running a Full size laser cutter with rd works & lightburn. None with glowforge but using the one at school for a school project
I cut 17 of these ornaments(just the inside as they purchased these as precut blanks) —6 had major issues, largely at the edges of the machine. I recut the 6 using the center of the bed and 4 were fine, 2 were strangely messed up.
As I have no glowforge knowledge, I have no idea how these overlapping layers became misaligned to each other (but fine on others)and would appreciate any feed back on solutions so the school gets more reliable cuts.
This has 4 layers - the order was light engraving (all text but the name), dark engraving (the name), line engraving (pc and circle) and cutouts. The material was 2.5mm ply. Nothing moved AFAIK.
