The nozzle does not extrude filament or the filament is not smooth during extrusion and printing

Extrusion failure when the nozzle extrudes the wire or the nozzle suddenly stops in printing process.

1. Material problems (wire used up, knotted, damp, broken, uneven diameter)  

• Rearrange unrolled wires
• Put in a drying oven for drying
• Replace with new materials or reinstall materials

2. Nozzle plugging  

• Clean or replace the nozzle
  

3. Nozzle height and platform compensation value setting is unreasonable  

• Reset nozzle height
• Calibrate the platform manually (using calibration sheet)

4. Nozzle CFC cable is damaged and the contact is poor /nozzle FFC adapter cable 

• Turn off the power and check if the CFC cable of the nozzle is damaged, and replace if yes
• Check the nozzle FFC cable for damage, if replace if yes

5. Nozzle (nozzle plate, nozzle motor, temperature control components, etc.)

• Turn off the power, remove and replace the nozzle board
• Turn off the power, remove the nozzle, and replace the integrated liquefied gas;
• Turn off the power and replace the nozzle motor
• Turn off the power and replace the nozzle assembly

6. Mainboard damaged
