Duet2 Wifi Driver 3 overheat issue
-
I have Duet2 Wifi, and accidently disconnected an extruder motor while the control box was on. I plugged it back in, and now it gives an error message that driver 3 detected a temperature overload, and the driver chip next to the extruder motor plug instantly gets incredibly hot, and has what looks like melted spots. I unplugged the motor, and one by one the heater, fan, thermistor, but it still does the same thing, and will not turn. I tried plugging in other motors, and the result is the same. I checked the wiring, it all looks OK. Any help would be appreciated!!

That's a pretty huge no-no. There are few ways to really kill a duet, but that's one of them.
If you have a spare driver you can remap the axis to use the spare instead and then disable the failed driver to suppress error messages.

Thanks very much for the quick response! I'm struggling with the mapping, I'm getting a whole string of errors relating to a "non-existent tool". Also, Drive 3 (the bad one) still gets hot. The board has several spare drives because I'm using the breakout extender board. I only have one extruder, which is plugged into Heater 0, Drive 4. Here is what I have:
M569 P0 R-1 ; Drive 0 disabled
M569 P1 R-1 ; Drive 1 disabled
M569 P2 R-1 ; Drive 2 disabled
M569 P3 R-1 ; Drive 3 disabled
M569 P4 S1 ; Extruder goes forwards
M569 P5 T2 ; 2 microsecond minimum step pulse width for x-axis
M569 P6 T2 ; 2 microsecond minimum step pulse width for y-axis
M569 P7 T2 ; 2 microsecond minimum step pulse width for z-axis
M584 X5 Y6 Z7 E4 ; Apply custom drive mapping (X=Drive5, Y=Drive6, Z=Drive7, E4-Extruder1)What am I doing wrong?

you might be able to desolder the chip
