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?
Without more information it is hard to say. What hotend do you have? What fan (manufacturer, model number) is cooling the hotend? Did this happen to you before or was it printing fine? Did you change anything?
