When using a 0.2mm nozzle on the a1 mini, a knocking-like noise occurs when the filament is being fed. Is there any way to deal with this? The link below has a recording of the noise.
When using 0.4mm, this kind of sound did not occur.
Looks like your nozzle might be partially clogged.

Thank you for your response. In another person’s question, it was suggested that cleaning the extruder could help, so I tried it too, and it worked.
