Troubleshooting
③ Nozzle clogged. Please try to briefly heat the print head to a
temperature higher than 230°C and manually push the filament into
the extruder. You can also clean it with 0.4mm nozzle cleaning
needle. If it doesn’t work, you may need to replace it.
④ Not enough cooling for the hotend.
⑤ The printer has been working above the maximum speed for a long
time, please reduce the speed.
⑥ Check whether the extruder is normal and whether the friction force
of the extruder to the filament is sufficient. Try to tighten or clean
the extruder wheel.
4. Filament leaking
① Nozzle, heating block or throat tube is not tightened properly, try to
fix/replace it after cooling or contact customer service.
5. Layer shifting
① Print head moves too fast, please slow down the print speed.
② Check the belts and driving wheels and ensure they are properly
installed.
③ Drive current is too small.
6. No sticking to the bed
① The nozzle is too far from the platform, please try to re-level; at the
same time set the "initial layer thickness" to 0.2 in Cura, and set the
"initial layer line width" (for example, set to 150) to improve the first
layer adhesion.
② Print too fast at the bottom layer speed, reduce it to ~20mm/s
③ Ensure that the print platform is clean
④ Add a brim or raft to the model in slicing software
