Was carving a sign, then about 25% done, the machine randomly stopped cutting, lifted the spindle, then returned to the start (like it behaves when it finishes a carve).
Weird I thought. So, I told it to do the carve again, use the last position, then the machine moved forward a bit to where the workpiece wasn’t at.
No power outages, never had this issue before.
Edit: I will add, it was cutting out a snow flake in a very small spot, so I wonder if maybe the machine felt there was an issue because it didn’t do alot of X/Y movement.
