Help. Print stops extruding Toolboard Therm reads 2000c
-
Today on my Duet 6HC + 1LC I've run into a problem where while printing the 121.temp0 sensor reports 2000c and the heater turns off the printer continues to print (no longer extruding)
I receive no indication of an error until I cancel the print then i get
Error: Board 121 does not have heater 1 3/27/2023, 9:59:39 AM Error: Failed to switch off remote heater 1: Board 121 does not have heater 1 3/27/2023, 9:59:39 AM Error: Failed to switch off remote heater 1: Board 121 does not have heater 1 3/27/2023, 9:59:39 AM Error: M106: Board 121 doesn't have fan 0Oh before that while the printer was printing in aire I also got

the M122 B121 log show this about the time i'd estimate it all went bad:

@Nurgelrot I have the filament runout manually disabled if anyone see that -It's not part of the problem
-
@DC42 The M122 from the 1LC (comes after the main M122 report above) is reporting a watchdog reset, is the stack trace any use?
-
If the problem persistent after a restart or is it working normally again?
-
Is the hotend grounded?
-
@Phaedrux Yes everything should have been correctly wired and the problem did occur again two more times. I replaced the toolboard and that has solved the problem. I'm working under the assumption that I cooked the previous toolboard. As I have temps reaching 80+ C reported from the board for long periods on an identical build that has not been in service as long. It just a guess right now but... Will figure out how to drop the temps and continue to watch it.
