3 MK3s/MMU2 error: tmc driver overtemp
Hello.
Yesterday I replaced the heater cartridge, PTFE tube, nozzle and a black printed part of my E-axis. When I finished reassembling the E-axis I turned my printer on and began to calibrate XYZ and calibrate first layer height. During this process something began to smell like it was burning. This concerned me, but the printer seemed to be working fine. So, I continued to print a benchy. 10 minutes in, the print abruptly stopped. The printer made a loud beep and displayed the text: TMC DRIVER OVERTEMP on the lcd.
When I restart the printer and when I switch the printer off and on again the lcd will flicker for about 10 seconds then start up normally. When I attempt to print something, it will abruptly stop about no more then 10 in. Then the printer will make a loud beep and the lcd will violently flicker for 10 seconds after that the printer (not the print itself) will restart automatically. However I wil not get a TMC DRIVER OVERTEMP on the lcd.
Any help?

I would suggest to contact Prusa Live Support. They can walk you through the troubleshooting steps.
My guess is that you installed wrong heater cartridge and burned something on the board. But again Prusa Live Support is best place to figure that out and get a replacement parts if needed.

what firmware version are you running? there is an issue with some old version of the printer FW causing overheating of the transistor for the heated bed, see https://github.com/prusa3d/Prusa-Firmware/issues/1636
where did you get the new heater cartridge from? It is very important that it is rated for 24v, using a 12v cartridge on a MK3 will definitely fry something.
