After engraving 4 coasters when I loaded the next 4 the laser moved 15mm on the y axis. Looking for a reason. The one on the left is the first one the one on the right moved 15mm on the y axis.
That can happen if you are not using Absolute Coords.
It’s on a mopa galvo. I am using absolute, and the only thing I changed was new coasters. Everything else was the same. No changes.
