  • From the picture belongs to the print midway plug, extrusion is not enough
    1, check whether the normal rotation of the axial fan of the nozzle
    2, printing in the extrusion motor is normal rotation
    3, tighten the extrusion clamp screw, increase the extrusion pressure
    4, check whether the extrusion clip is broken
