Idler cannot move

What happened?

The printer is showing the message "The Idler cannot move properly. Check for anything blocking its movement. Check if the wiring is correct.". This happens when the idler is not able to move properly during operation.

How to fix it?

• If you are using the MMU for the first time, check if the motors are connected in the correct order.

• Clean any debris around the idler.
• Check the tension on the idler screws. Having it too tight might prevent the idler from moving.

• If the issue persists, check the Idler assembly.
