Cold pull looking weird?
I'm trying to diagnose a "stuck filament" issue on my MK4 (6.2.6+8948) with MMU3. The stuck filament detection page sent me to the loadcell troubleshooting, which I tried completely. Neither the screw-loosening nor checking (and vacuuming debris from) the loadcell helped.
So now, I'm trying a cold pull. My firmware is new enough that it happens automatically. I did two pulls, but the filament coming out isn't conical like I see in the example images. Are these two appropriate looking cold pulls? (Note: prior printing was with black and white PLA, so the this pink PLA should be high contrast to show debris.
RE: Cold pull looking weird?
While I'm still not sure if my cold pull above looks correct, I followed the directions on the under-extrusion article as pointed to by support. It seems to have fixed my root cause issue.
