This prompt indicates that the feeding motor at the CFS hub outlet encountered excessive resistance during operation, causing motor overload. Possible reasons include:
Excessive PTFE tube resistance: The PTFE tube is bent, clogged, or damaged, preventing smooth filament passage.
Filament tangling or jamming: The filament on the spool is tangled or jammed, affecting normal feeding.
Filament quality issues: Uneven filament diameter or abnormal quality causing jams during feeding.
Check the PTFE tube: Inspect the PTFE tube for bends, clogs, or reduced inner diameter, ensuring smooth filament passage. Replace or adjust the tube if issues are found.
Check the filament spool: Confirm that the filament on the spool is not tangled, knotted, or jammed, causing increased feeding resistance. Manually untangle the filament if found.
Check filament quality: Verify that the filament diameter meets standards (normal diameter is 1.75mm ±0.05mm). If the filament diameter is uneven or has other quality issues, consider replacing it.
Inspect the PTFE tube: Check for bends or reduced inner diameter that may obstruct feeding, replace if necessary.
Check the filament spool: Manually organize the filament on the spool to ensure there are no tangles or jams.
Check filament diameter and quality: Use measuring tools to confirm the filament diameter is within the normal range. Replace if quality issues are found.
Manual feeding and unloading test: Perform manual feeding and unloading tests to ensure the motor can operate without excessive resistance and feed normally.
