This is the sort of system I am running,
With my airtripper bowden coming from the top of the rostock.
However, I am not extruding. It only jams.
The hotend is getting to the correct temperature,
I just un-clogged the hotend also.
My hotend is a j-head mk5 .4mm nozzle with 1.75mm abs
Any ideas on what could be causing a jam?
If I remove it from the nozzle, it extracts and retracts the appropriate amount.
It just seems as if the stepper motor is not completely strong enough to push the filament through.
I was able to stick a .2mm strand of wire up the nozzle end without a problem.
And I can get filament extruded by pushing it by hand.
