Duet 3 Software Reset when starting print
-
Having a weird issue whenever I start a print job on my Duet3. The bed heater starts warming, but within a couple of seconds I get a bunch of messages on the UI that there's been a reset and the job stops.
Using M122, I get the following diagnostics:

Please upgrade to 3.01-RC2 and see if that fixes the problem.

Not sure if it's in any way related, but M500 doesn't seem to want to save autotune results either, this is what the M500 writes to config-override.g:
; config-override.g file generated in response to M500 at 2020-02-27 00:43
; Heater model parameters
M307 H0 A C D S V B0
M307 H1 A C D S V B0
; Workplace coordinates - Ethernet -

Could it have something to do with running off of the virtual sd card on the SBC, and not off of a dedicated card on the board itself?
-
Solved, or, no longer seeing the issue - I THINK it has something to do with the heater model which was coming in from config-override.g. I manually entered the correct model (because M500 wasn't saving anything other than empty values), forced the config-override to load on reboot, and... all my problems have gone away. (well, except for a inconsistent z-probe offset, but that's on me)
-
Do you have a copy of the config.g and config-override.g that provoked the problem?
Not saving the heater model parameters correctly is a known issue in Duet Software Framework.
The software reset data in the M122 reports that you posted suggests that in both cases, it was trying to use an invalid tool object at the time.
