¶ Phenomenon description
The nozzle does not discharge filament when printing starts.
¶ Cause analysis
-
Filaments are wrapped around the material rack
-
Filament are not assembled in place
-
There are residual filament in the nozzle and throat
-
Extruder jams
¶ Troubleshooting and solution
- Check whether the material rack is tangled and whether the anti-tangle material rack is correctly assembled.
- Use scissors to cut the filament at 45° and straighten it, unlock the gear extruder and insert it into the feed port.
- If you feel that there is resistance and cannot continue to push down (the filament is loaded about 22mm), lock the gear extruder and perform the automatic feeding function.
- Heat the nozzle to 240 degrees, straighten the filament, open the gear extruder, and feed the material manually.
- It is recommended to use option 2 for loading filament, automatic feeding; please note that whether it is automatic feeding or manual feeding, the filament must be straightened.
-
The above methods cannot feed the filament. Please refer to the after-sales video - cleaning the nozzle through the needle to clean the nozzle.
