If you installed it correctly and it worked for you on FreeDi, this issue can sometimes occur.

It’s a common error that this series faces and is not related to FreeDi at all. The cause is typically one of the following:

  • The toolhead MCU is stuck in a non-operating mode (can often be reset by a power cycle)
  • A hardware issue caused by a loose connection in the USB-C cable that connects the mainboard to the toolhead (requires replacement)
