What happened?

Each of the three stepper motors on the MMU unit is controlled by a TMC driver on the control board. In case there is an unexpected communication issue between the main microcontroller and the Idler motor TMC driver on the board, the error is shown.

How to fix it?

Make sure you are using the MMU3 with the PD-board addon attached.

Verify all the cables are in good condition and the connections are stable.

Do not move, connect or disconnect the cables while the printer is on!
