Just had a mid-print reset on 2.01b2

I was standing there watching the printer. None of the axes were even close to their endstops and I wasn't touching the printer.

Last reset 00:08:56 ago, cause: reset button or watchdog

doesn't say which it was though so it's not all that helpful. Can we get that message enhanced to say which button or which watchdog it was?

I also had an issue earlier today where the thermostatically controlled heatsink fan just stopped but the print continued. A few minutes later the filament jammed in the hotend and I had to take everything apart to clear it.

Thanks for your report. On the Duet rev 1.04 we should be able to tell the difference between a watchdog reset and the reset button, but on the older Duets we can't. Unless something is fouling the reset button on your Duet, it's probably a watchdog reset. What's odd is that there is a second watchdog that normally goes off before that one, and it hasn't in this case.
