If manually adjusting the gear doesn't work, you'll need to disassemble the extruder gear. For detailed instructions, refer to the Kobra 3 Combo extruder gear replacement guide.
After pulling out the filament, please cut off the bent part to ensure it is straight, then reinsert the filament. In addition, it is recommended to use the official filament to avoid using non-standard size reels and overly heavy filaments that may affect the feeding of filaments.
Note: The filament passing through the ACE Pro is due to bending. Please ensure the filament is straight when inserting.
