I have tried twice to engrave a small (80 X 76 mm) picture on a coaster size piece of birch. Both times it has gotten about 30% into the job and then it randomly tries to home itself. I get the ALARM 3: Homing error and the job comes to a complete stop.
I am still working out the bugs at this point, but I have to say, had this happened in the middle of a larger job on higher quality media, I would have lost my mind.
I am running a Cohesion 3D Laserboard with the GRBL - LPC firmware. I have gone through all of the processes of setting up the machine, it jogs where I tell it, and has done a few small projects without issue. Can you help me understand why it would be doing this?
