Implausible SuperFINDA reading. This error happens when a filament is detected by the SuperFINDA sensor although the MMU doesn’t have a record of any filament being loaded. It is unsure of which position the filament is loaded in so it can’t perform the unload automatically.
This usually 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 if the printer was restarted during a load/unload operation before it was completed.
