TMC Driver overtemp when nozzle fan starts + Cannot flash firmware.
Hi ! After 4 years of reliable service, my MK3s started to act up. The screen flashes and when the nozzle fan starts I get the TMC Driver Overtemp error. Also, I cannot flash any firmware. Prusa support told me I needed a new board. I tried to find more info on which component of the board might be the culprit without any success. Do you have any thoughts on the issue or fixes to suggest ? Thanks !

I found the issue, the ground wire on the print fan was frayed and was touching the 5v wire. Thanks for your input !

Possibly one or more driver modules (TMC 2130) are defective. The components are soldered onto the board and are somewhat more difficult to replace. This is probably the reason why Prusa recommends a new board.

Hi ! Thanks for the answer. Do you think a faulty driver would also explain the firmware flashing issue ?
