Hi all of you
I am experiencing a new problem that i never had before.
When printing it suddently requires alot of power to push the filament, and almost nothing exit from the nozzle, and few seconds after, it will restart extruding well, but in the mean time I guess the pressure increased in the hotend leading to too much plastic extruded.
My extruder is really powerfull, meaning that if it's stop extruding it's because it's impossible to do so, even by hand.
I am printing 3.00 mm pla with a bowden set up and a e3d metal hotend imitation.
I am out of ideas for the cause of the jamming, the heat breaker is heavily cooled down...
