The filament has been fed to the break detection sensor of the extruder, but cannot smoothly pass through the extruder gear to continue extrusion. Possible reasons include:
Filament jammed at the extruder gear: The filament cannot be pushed to the hot end by the gear.
Filament grinding: Insufficient friction between the filament and the gear, causing the filament to be ground.
Hot end clogged: The filament cannot pass through the hot end normally, resulting in extrusion failure.
At this point, the system detects an extrusion anomaly, possibly accompanied by filament slippage or inability to extrude.
Try clicking the unload button: If the filament can be unloaded normally, the problem may be related to the shape or damage of the filament tip. Cut off the damaged filament tip and reload the filament.
Deal with hot end clogging: Follow the clogging handling process for the corresponding printer, check and clean the blockage in the hot end. Ensure the filament passes through the hot end smoothly, restoring normal extrusion function.
Check the extruder gear and filament: Look for slippage of the extruder gear, filament knotting, or poor contact between the gear and filament. Clean the extruder gear and ensure sufficient contact between the filament and gear.
Check filament condition: If the filament is ground or damaged during extrusion, cut off the damaged part and reload.
Check if the hot end is clogged: Clean the blockage in the hot end according to the clogging handling solution, ensuring the filament can pass through smoothly.
Check the PTFE tube: Confirm that the PTFE tube in the filament path is not deformed or blocked, avoiding excessive feeding resistance.
Reinitiate the feeding operation: After troubleshooting, perform the feeding operation again to ensure the filament can smoothly enter the extruder.
