Ensure Secure Motor Connections:
Firstly, please inspect whether the connections between the motor wires and the motor terminals or the mainboard ports are secure. Make sure there is no looseness or poor contact. If any issues are found, reseat the connection wires and perform a power-on test to verify if normal operation is restored.
Motor Swap Test:
If the motor still does not respond after reseating, the next step is to swap the suspected faulty motor with a motor that is known to be working properly at the mainboard port. This step can help us further determine the location of the fault.
Fault Diagnosis:
-
Motor Wire Failure:
After confirming that the motor itself is not the issue, try swapping the suspected faulty motor wire with a wire from a working motor and test again. If the test results are normal, then it can be determined that the problem is with the motor wire. If the problem persists, further inspection of the motor driver is required.
-
Driver Failure:
When both the motor and motor wire are confirmed to be without issues, the next step is to check the motor driver. If the driver is found to be faulty, it may be necessary to replace it with a new one to resolve the issue.

1. Material Clogging Due to High Printer Chamber Temperature
- Reduce the Bed Temperature: Lower the bed temperature appropriately to prevent the material from overheating and becoming too soft.
- Use Heat-Resistant Materials: Opt for filaments with a higher heat deflection temperature, such as PLA or PETG.
- Enhance Cooling: If the printer is equipped with an enclosure kit, open the front door or top cover during printing to assist with heat dissipation.
2. Extrusion Gear Malfunction Causing Poor Extrusion
- Test the Nozzle: Set the nozzle temperature to 240°C, insert PLA filament, and press the extrude button. Observe the extrusion of the filament. If the filament falls vertically smoothly and the strand is long and smooth, the nozzle and extrusion gear are functioning properly. On the contrary, if the strand is short and rough, it may indicate a narrow nozzle channel or extrusion gear malfunction.
- Inspect the Nozzle and Extruder: Unscrew the nozzle, set the nozzle temperature to 220°C, and manually push in PLA filament. If the filament extrudes smoothly, the nozzle channel is clear; inspect the extruder gear for wear or blockages by foreign objects and replace or clean as needed.
3. Clogging Caused by Soft Filament
- Avoid Soft Filaments: Certain soft filaments, such as TPU 85A or damp PVA, can be flattened by the extruder gears, leading to clogging. Avoid using these types of filaments for printing.
4. Filament Diameter Variation
- Check Filament Diameter: Filament may become thicker locally after bending or compression, or thinner due to extruder wheel wear, affecting normal extrusion. Remove the filament, trim off the parts with abnormal diameter, and then proceed with printing.
Common Causes and Solutions for Nozzle Clogging
1. Slow Melting Speed at the Nozzle
- Incorrect Temperature Settings: A nozzle temperature that is too low can prevent the filament from extruding smoothly. Please check and ensure the correct printing temperature is set. If the problem persists, it may be due to an aged or damaged nozzle heater, which would require replacement.
- Printing Speed Too Fast: High-speed printing can lead to insufficient melting of the filament within the nozzle. After clearing the nozzle, reduce the printing speed or appropriately increase the printing temperature, then try printing again.
2. Small Internal Chamber of the Nozzle
- Particle Residue:
After using filaments containing fibers or particles (such as PAHT-CF, PA-GF, etc.), the nozzle may become clogged with residue. Regular cleaning and maintenance of the nozzle are crucial. Cleaning methods include: unscrewing the hot end, heating to 250 ~ 280 ℃, using a hex key or other metal tools to scrape the inside of the nozzle, flushing with regular filament, and using a nozzle needle to clear the path until the material extrudes smoothly (judged by manually pushing PLA filament into the nozzle at 220 ℃). If the nozzle cannot be cleared, a new nozzle should be replaced.
- Nozzle Diameter Selection:
To reduce the risk of nozzle clogging, it is recommended to use nozzles with a diameter of 0.6 mm or 0.8 mm. Avoid using 0.2 mm nozzles, as they are highly susceptible to clogging.
- Nozzle Aging:
Nozzles that have been used for a long time may accumulate a lot of residue, leading to poor extrusion. Clean the nozzle until extrusion is smooth before use (same method as above). If it cannot be cleaned to a smooth state, it is advisable to replace it with a new nozzle.
Precautions When Changing Filament in the Nozzle
- From High-Temperature to Low-Temperature Filament:
After printing with high-temperature filaments (such as PAHT-CF, PET-CF, PPS, PPS-CF, etc.), if you want to print with low-temperature filaments like PLA, TPU, PETG, etc., it is recommended to first set the nozzle temperature to 250 ~ 300 ℃, manually extrude the high-temperature filament, then load the low-temperature filament and manually extrude it to ensure that the remnants of the high-temperature filament and the new low-temperature filament have both been expelled from the nozzle. Afterward, reduce the nozzle temperature to 220℃ ~ 240 ℃, continue extruding during the cooling process, until the temperature stabilizes, and confirm that the new low-temperature filament can flow smoothly from the nozzle, then prepare for the next print. If you find that extrusion is not possible during the flushing process, increase the nozzle temperature and use a nozzle needle to clear the nozzle.
