Have you ever seen this type of print failure? (lemmy.world)

Pretty sure I'm having heat creep up the Bowden tube, as it's getting jammed a few cm back from the hot end and then can't push the filament any more. When I get it out there's a little molten bulb at the filament.

In this fail, I think it jammed as usual and the extruder found a way to keep going.

I tried turning down the hot end from 215 to 200 and it's still failing. My cooling fan is running at 100%.

This is the third time I've had this print fail at about this layer, around 1 hour into what will be a 26 hour print.

Any ideas?

Coming back to say that I got it to print based on the suggestions in the thread.

I settled on a 3mm retraction length in PrusaSlicer which left a minimal amount of stringing. Printed flawlessly after that change.
