Unload manually #04506 (MMU)

What happened?

Implausible SuperFINDA sensor reading. This error occurs when the SuperFINDA sensor detects filament inside the Selector, but the MMU has no record of any filament being loaded. As a result, it cannot determine which filament position is loaded and cannot perform the unload automatically.

This often happens due to a malfunctioning or improperly calibrated SuperFINDA sensor.

Another potential cause could be if the filament was inserted into the selector manually, bypassing the menu/buttons, or restarting the printer during a load/unload operation before it was completed.


How to fix it?

  • Verify there is no filament in Selector and SuperFINDA sensor isn’t detecting a filament.
  • If filament is loaded, unload it manually or clear any obstructions triggering the SuperFINDA sensor.
  • Re-calibrate the SuperFINDA sensor.
    Also see the FINDA toubleshooting article.
  • Use only the menu on the printer to load or unload a filament during regular use.
