I have a 3D printer at home creality ender 3 S1. I have a problem with the filament not moving through the extruder during extrusion. The tooth rotates during 3D printing, but the filament does not move through the extruder. I cleaned the entire extruder, but there was no clogging. I wonder what could be the problem?
Check the ribbon connecter on the sprite. Do this while extruding at temp (manually) if it runs okay, something else is up!
Check the extruder tensioner, it might be too loose.
