Unable to read tmc uart ‘extruder’ register IFCNT

Do I need a new board? I have re-seated all the wires but still encountering this issue. This was after a clog issue where I heated the hotend to 300 degrees. I was then able to successfully run the calibrate z-offset. Now I get the error with any print or even calibrate z-offset.

Unable to read tmc uart ‘extruder’ register IFCNT once uderlying issue is corrected, use the ‘FIRMWARE_RESTART’ command to reset the firmware, reload the config and restart the host software. Printer is shutdown

Manual extrusion works but extrusion via the web interface or through z-offset calibration or print results in the error. Bad extruder motor?

The uart pin for the toolhead is PA12. Check this connection and confirm it is fully seated.

Confirmed. It is seated securely. Removed both and connected again. Heated up the nozzle and tried to extrude from MainSail and encountered the error.

Your klippy.log will contain information on which motor driver is in an error state.

I assume from your post it is one of the 4 Z motors NOT the E motor.

How do I tell this from the klippy log? Not sure if I can upload the klippy log here.
