I’ve been having this issue for awhile now since I reset up my lightburn.
My laser will no longer return to the origin point when a job is completed. If I swap out ornaments, mugs, shot glasses I have to “Home” the machine for each and every run.
When the laser finishes the job it sits at the last point it lasered vs returning to the origin point. When manually moved back to the origin point it will no longer trace correctly and will engrave off. This will happen in both flat engraving, flat cuts, and rotary engraving. If I have to do another pass sometimes I can hit start without moving it and it will run over the exact same points even without being over the correct "Origin " point. But sometimes it will still be off so it isnt reliable.
If I am cutting a larger piece I usually cant hit start and expect it to cut along the same lines if I feel it could use another pass.
Flat engraving
Rotary (Interest points Beginning trace, 3:15 when it ends, 4 with new piece and name inserted, and 4:25 and 4:45)
