Have you ever seen this type of print failure? - eviltoast

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?

    That is a very odd failure so not 100% sure. If I had to take a punt I would say the nozzle jammed from the mentioned heat creap issue, eventually the silk pla broke in the extruder as it’s very brittle, combined with retractions. It then was then able to work its way out and make some noodles for you to enjoy.
