it said extruder not extruding nirmally for like the 5th time since i got my a1 and i checked the extruder and saw this
how should i even clean this
Scroll down to the topic “Extruder.” Watch the video. 
However, you will probably need more than just a little air, contrary to what is shown in the video.
Otherwise, you can follow these instructions if you want to remove the entire gear; the part about replacing the motor is not relevant and can be skipped.
also what do yall think caused this
grinding in-place while dealing with blockage, or bad filament.
