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?
What retraction settings do you use?
Using the PrusaSlicer retraction defaults for my Ender 5 plus: 6mm retraction.
I’m going to try again with less. I’ve never had this type of jam before so I think it’s probably something unique to the print, but maybe this will let me finish it.
