(1) Push the material inward to see if it can be discharged normally.
The user can hold the wire by hand and push it inward to see if it can be produced normally.
(2) Tighten the screws above the extrusion
There is a screw above the extrusion device. If it is loose, the extrusion wheel will not be able to squeeze the wire and the nozzle will not be wireted. The user can tighten the screw a few times and tighten it.
Special reminder: If the screw is too tight, the wire will be squeezed too tightly, so the user should grasp the degree of adjustment.
