MCU 'mcu' shutdown: ADC out of range
I recently had to change my hot end assembly on my enclosed V-core 3.1 after about 1000h of it working pretty well. After installing the new hot end I was able to print for another 10h until it crashed with the following message "MCU 'mcu' shutdown: ADC out of range". I found out that the thermistor connector was not properly connected so I changed it to make sure it wouldn't happen again, and now the connection is good but that error remains and I have no clue where it come from.

upload your klipper.log file please
extruder: target=0 temp=-50.5looks like your extruder thermistor is still to blame. How did you check the connection was good?
I check the continuity from the motherboard to the connector
Did you change the type of thermistor? is it still
ATC Semitec 104GT-2?I'm not sure. I bought the same exact hot end but the connector for the thermistor was different that's why i had the first problem. Maybe they changed the model since I bought the first about a year ago
And what's weird is that I was able to print for about 10h with the new hot end, so it seems unlikely the model is different
well then I would check your wiring and connections again. Maybe a bad crimp job or something. When doing the continuity check, unplug the thermistor from the board
Alright i'll try that, thanks a lot for your help !!
