¶ Problem Symptoms
- Clicking "Load Filament" does not extrude filament.
- Filament suddenly stops extruding during printing.
¶ Possible Causes
- Nozzle or throat tube clog
- Filament jam inside the extruder
¶ Solutions
Warning: All disassembly should be performed with the printer powered off.
- Ensure the filament is fully inserted.
Click "Load" and wait for the nozzle to heat up to 240°C and automatically load the filament.
- If no filament is extruded, use the silver needle from the accessory box to clear the nozzle, then try extruding again.
- If the filament still doesn’t extrude, try unloading it.
- If it unloads normally, cut the filament at an angle and reload.
- If it fails to unload or reload, disassemble the effector for inspection.
- Remove the handle screws, cut the filament, and pull it out.
- Disassemble the effector to check for clogs in the throat tube or extruder.
- Inspect the heatsink for any residual filament blockage inside.
- Pay special attention to melted filament stuck in heatsink gaps caused by high-temperature jams.
- Check the nozzle and throat tube for any signs of clogging.
- If needed, remove the nozzle and throat tube, and use a needle or cleaning tool to clear them.
- Inspect the extruder for:
- Residual filament buildup
- Slipping gears or feed issues
