Model: U1
¶ Issue Description
- Filament feeder shows no response, neither white nor red LED lights up.
- Auto loading failure, unable to load filament, and red LED is on.
¶ Possible Causes
- Filament feeder has no power.
- Filament feeder or toolhead is accidentally disabled.
- Poor cable connection.
- Module itself is faulty or there is a mainboard issue.
- Unable to load filament.
- Residual filament inside the toolhead.
- Filament jam occurs during loading.
- Nozzle is clogged.
¶ Troubleshooting Steps
¶ Filament feeder has no power
- If no red/white LED lights up when inserting filament, check if the cable is properly connected.
- If no red/white LED lights up when inserting filament, the filament feeder might be accidentally disabled.
- Check Method: On the touchscreen, navigate to "Settings > Print Preferences > Auto Loading > Enable".
- If no red/white LED lights up when inserting filament, the toolhead might be accidentally disabled.
- Check Method: Connect to the machine's IP address and check if the filament runout sensor is accidentally disabled.
- If the LED still does not light up, try swapping the left and right filament feeders to isolate if the issue is with the feeder module itself.
¶ Filament feeder unable to load filament
- Error Code: 0001-0525-0003-0003, feeder red LED is on.
- Check for residual filament inside the toolhead. If the filament indicator on the screen shows a "?", it indicates filament is present.
- Error Code: 0001-0525-0003-0011, feeder red LED is on.
- Check if the filament is tangled or if resistance from a dryer box is too high.
2. Check the filament spool weight; it must be less than or equal to 1KG.
3. Check the filament jam location:
- If the jam is inside the feeder, unload the filament and check for chewing. Remove the damaged section and retry loading.
- If the jam is in the middle of the filament tube, check if the tube is deformed or bent, preventing filament movement.
- Error Code: 0002-0525-0003-0032, if the filament does not reach the toolhead's runout sensor and loading continues, the feeder red LED lights up.
- Check if the filament tube is fully inserted into the toolhead connector.
-
Error Code: 0002-0525-0003-0051, if loading reaches the nozzle and the nozzle pre-extrusion fails, the red LED lights up.
- Check if the nozzle is clogged and cannot extrude.
-
If the issue persists, analyze the problem based on the on-screen error code and its description. If still unresolved, please contact us.
