maybe i am doing things differently.
First, it is GRASS GREEN ninjaflex so ill try even slower. i think i did 30-40mm/s last time.
I put the filament in, feed it, extrude til clear. turn off pre heat. if tried pulling immediately, letting it cool to 100, or 50c and at those low temps it seems to just break off.
I pull from the top with the arm that holds the filament against the gear open, so it wont crimp it.
thoughts?
