My Ender 2 is currently experiencing a problem. During prints, the filament is somehow getting stuck in the hotend even though the nozzle temp is normal. When the filament gets stuck. I can push the filament through the nozzle fine manually and after that it starts to extrude properly again. The extruder stepper motor still spins normally during this.
I made sure that all screws are tight and that the extruder arm pushes the filament into the teeth gear properly. I took apart the hot-end and everything was normal.
I cant think of what could cause this problem.
