Comment on Help me identify the problem: wet filament, bad z-height, or clogged nozzle?

My money would be a clogged nozzle. But a better photo (close up) may be helpful. Things I wonder…
Does the filament come out and curl back up during preheat?
Is your heat block messy with residue?
Have you tried a cold pull, or pulling the nozzle and cleaning/replacing it?

I forgot until looking at your photo that the mini uses a Bowden tube, not direct drive like the MK3S+. Did you replace/switch the nozzle around the time this all started happening? With Bowden tubes, there are a few problems that can arise that you don’t see on direct drive. The end of the Bowden tube (that is inside the extruder/hote end assembly) can get deformed or clogged. If you can check that, you may find an issue. Other than that, when swapping nozzles I always had to put the nozzle in part of the way, then push the Bowden in further, then tighten the nozzle.
