Locations that may cause plugging
1. Gear set: confirm that there is no waste residue filament in the extruder gear set,
2. Nozzle: withdraw the filament, heat the nozzle to 240 °, and use the attached 0.3mm metal needle to pass through the nozzle to ensure normal passage without resistance.
3. Metal throat: remove the hot end and observe that there is no residual filament in the throat, otherwise use tools to remove the residual filament or replace the metal throat
After confirming the above positions, operate and load the filament. First, confirm that the filament is straight and free of winding, deformation, bulge and inclination. Confirm that the filament passes through the driving wheel and idler wheel group of the extruder. Introduce the lower guide pipe and enter the hot end through the throat. When a perfect filament is extruded from the nozzle.
