Hi, this question is mainly for dc42, or anyone familiar with RepRapFirmware 1.15 beta (downloaded and flashed yesterday from dc42's github).
I had a reset happen while the printer was sitting at idle at temp.
I'm running a Duet 0.8.5, and just recently updated to the latest beta firmware from 1.11. The only thing I can think that might have changed (besides calibration) is increasing my xyz stepper currents from 1100 to 1300, but I have a 120mm fan blowing on the underside of the duet.
Any idea why this might happen? CPU temp? There didn't seem to be much else in the M122 response:

It's a long time since I have seen a watchdog reset. As to the cause, I guess that either there is a firmware bug that I don't know about, or you have an intermittent hardware fault, or a hardware transient caused it. Did you have the USB port connected at the time? Mains ground transients fed through the USB cable can cause odd behaviour.

I did not have the USB connected at the time. I did just move the printer around a lot, I should triple check nothing got damaged.
I do know that my house, though a relatively new build, has weird power things going on when inductive loads like fans and refrigerator pumps shut off, sometimes causing my LCD TV to momentarily cut-off the display. Although the printer has been running in this environment for hundreds of hours at a time, so that seems unlikely unless the watchdog was changed from 1.11 to 1.15 in any way.

I've had no errant resets since this, and I've had the printer powered up for over 29 hours with no disconnect and the web interface was connected the whole time.
It's possible that the machine reset with a static electricity discharge from me. It's dry here and sometimes I electrocute everything and everyone I touch, and I've had discharges into the nozzle cause resets before. Would this be reported as a watchdog reset?

Yes, if a static discharge affected the operation of the mpu and cause the firmware to crash, that would result in a watchdog reset.
