Clear and Reassemble the H2C Extruder Assembly

Tools Required: Cleaning needle, appropriate hex key set, soft cloth or compressed air.

Safety Precautions: Ensure the printer is powered off and the hotend has cooled to room temperature before beginning disassembly.

1. Remove the extruder front cover by unscrewing the mounting bolts on the toolhead.
2. Carefully inspect the filament guide and drive gear area for trapped plastic fragments or debris; remove any identified particles using a pair of tweezers or compressed air.
3. Perform a cold pull on the hotend to ensure no residual material is blocking the internal nozzle path.
4. Use a cleaning needle to clear the nozzle tip of any remaining physical obstructions.
5. Examine the internal extruder screws and tighten them to ensure the assembly is properly aligned and the idler arm maintains correct tension against the filament.
6. Reattach the extruder front cover and secure all mounting bolts firmly.
7. Verify the fix by navigating to the touchscreen menu (Control → Nozzle & Extruder) and manually extruding filament to confirm smooth, silent operation without clicking.
