@dc42 well, I’ve attempted a chip replacement. Despite some lifted tracks there’s minimal remedial rework needed as far as I can tell…
I have no intention of powering up until I’ve dealt with the obvious bridge.

@dc42 it was becoming too hot to touch before the SD slot replacement; hence the heatsink
To answer @Phaedrux, it would be hard to calibrate without configuration provided by the microSD card in normal circumstances.
I expect the extruder could be configured in the console; and its thermistor connected to provide a figure for those commands.
I tried pointing a laser thermometer at the heatsink to get some idea of how hot the MCU was getting before disconnecting power when it reached the 80s per M122
@dc42 if M122 reports that the board has reset itself via software and/or that the MCU temperature is around/above 100°C the Duet is in a bad way?
@dc42 was part of a printer listing; operative state unspecified
@dc42 I'm not sure it's ever read uSD cards since I've had it
Hopefully this morning's soldering is still viable ![endoscope view of Duet SD socket]()

A new board is outside my current ad hoc budget ...
Have replaced the microSD socket; the problem persists.
@doctrucker the Duet seems unable to read any microSD cards presently.
@dc42 it is There’s a town here which shares a name with a village down there…
@dc42 or ?
I try to seat the card properly; have used canned air to blow out to no effect.
Reflowing the soldered joints is next on the list; spare parts are in the post... in case the hot air melts the plastic part
