Users may encounter filament sticking to the nozzle during the printing process, please try the following troubleshooting steps to verify if the issue can be resolved.
Unusual Phenomenon:
- Filament sticking to the nozzle.
- A large amount of filament is wrapped around the nozzle or hot end.
Root Cause Analysis:
- Nozzle is contaminated by consumables and foreign matter over an extended period of usage.
- Due to uneven heating bed, small print model or special high-temperature material ABS, the model is separated from the heating bed during printing, resulting in consumables wrapping around the entire nozzle.
- Nozzle was not properly locked during assembly, resulting in material leakage at the nozzle.
Replacement Method:
- Turn on the M5 printer’s power switch, click Control > Move on the display screen to raise the Z-axis of the nozzle assembly by 200mm, and move it to the middle of the X-axis for the nozzle to be easily accessible.
- Use a H2.0 hex wrench to loosen the four screws on the back of the print head assembly.
3. Move the upper cover and the nozzle cover of the nozzle assembly up with the type-C line and tighten it.
4. Use a H2.0 wrench to loosen the front bottom cover screws and remove the bottom cover. If the bottom cover is stuck and difficult to remove, please try preheating the nozzle and remove the blockage first.
- Click Preheat > Start Preheating on the M5 end, wait for the nozzle to preheat to 220°C, keep it warm for 10 minutes, use tweezers or needle-nose pliers to slowly clean the consumable on the nozzle.
Additional Tips:
a. Please pay close attention to the heated nozzle due to its high temperature to prevent burning yourself.
b. If it is not easy to clean the consumables, please try preheating the nozzle to 240°C. Additionally, if you are printing high-temperature consumables such as ABS and TPU, you can increase the preheating temperature accordingly.
c. Clean slowly and gently to avoid breaking the thermistor wire.
d. Please remove the air guide (the green component) first, and then use a heat gun to remove the connection part with the heating wire and the thermistor wire if the connection part is difficult to remove.
- After cleaning, preheat the nozzle to 200°C and lock the nozzle with a socket wrench.
- If the thermistor wire breaks during the cleaning process, please replace the hot end. For detailed operation instructions, please refer to the following article and video.
