duet 3 mini 5+ short to ground reported by driver 2
-
Hi
I've been using the Duet 3 mini wifi since i got without any issues and have not made any modifications lately.
But few days ago (maybe in coincidence with the 3.4.0beta6 update) it showed an error message (short to ground reported by driver 2).If I turn off/ on the printer or I press emergency stop few times sometimes the issue disappears and I am able to print again.
I already checked all the wiring many times and everything seems to be fine. Actually the printer is being working perfectly since March 2021.Duet 3 Mini 5+ Wifi V0.5 with Expansion Mini 2+, SBC and tool board v1.1
I think this is the exact same issue reported by another user here: https://forum.duet3d.com/topic/26124/duet-3-mini-5-short-to-ground-reported-by-driver-1

@juliann please can you post the M122 once the issue occurs. I see driver 2 is one of the Z axis motors so its unlikely to be moving wiring causing the issue but can you check that you can't recreate the issue by moving the wiring around. Also something to check would be to switch the motors in driver 1 and driver 2 at the Duet end, update your config to match, and see if the issue moves with the motor or stays with the driver.
