You might need to clean the plastic nozzle, for instance – if the under-extrusion occurs. Follow the next steps to clean the plastic nozzle:
- Heat the plastic extruder to the printing temperature (270 °C for Smooth PA).
- Clean the nozzle with a cleaning needle from the tool kit. To clean the contact surface of the nozzle, use the brass brush from the tool kit.
3. To finish the cleaning, feed about 50mm of plastic to the extruder.
