    1: wire feeder is adjusted too tight and extrudes the filament. It causes resistance and abrasion. Please adjust the arm of force properly until the occlusive and smooth condition.

    2: Turn down the retraction length. High retraction length causes abrasion.

    3: Check the filament feeder is stuck or not. If blocked, please clean it up.
