I had two rolls of identical filament for the AUX filament extruder. When the first roll ran out it can’t push the replacement roll through the Bowden drive. Since the filament can only go past the drive motor the new filament can’t load behind it? Any ideas?
Have a read of my recent post. Looks like the same issue with a different cause.
I read your post, sorry that’s happening for you. Mine is making a repeating ticking sound like the Bowden motor can’t grab the filament and it’s slipping. This has happened twice so far, It would mean I can never use the runout feature on the AUX nozzle?
I can’t answer that specifically. In my situation, there was a clicking/grating sound which I initially thought was the Bowden extruder slipping, but I was unable to confirm the source of the noise. I felt the Bowden extruder while the noise was present and there was no vibration there. After I cleared the nozzle, the noise stopped, so I deduced that it was actually the filament drive in the print head trying to advance the filament which was clogged.
