The display prompts: TC2854, filament detected in the extruder, affecting the cutter calibration. Please unload the filament and try again.
During Input Shaping calibration, which includes several steps such as automatic belt tensioning, cutter position calibration, and vibration compensation, the extruder must be free of filament for successful cutter position calibration. This prompt appears when the filament break detection is triggered during Input Shaping.
- CFS filament in use: Manually click "Retract". If cutting fails and reports unloading failure, unlock the motor, manually pull the extruder to hit the cutter push rod to cut the filament, then click "Retract" to unload the filament back into the CFS.
- Spool holder filament in use: Manually click "Retract". If cutting fails and reports unloading failure, unlock the motor, manually pull the extruder to hit the cutter push rod, then click "Retract". After successfully unloading, manually remove the filament as it cannot automatically retract past the filament detector in the extruder.
