Spontaneous reboot after print completed
-
I've been printing most of the day using the latest RC10 release. I had no problems until my last print of the day finished. I was looking at the print waiting for the bed to cool a bit and the Duet rebooted. I captured the results of the M122 and it shows that the software was reset by software due to being stuck in a spin loop.
