Hi,
I havent done anything to this thing yet. I hooked it all up and mounted to my K1 (speedy). The trouble that i am having is i cannot by hand push the filament through the stepper feeder expect for 1 will go through with a bit of force. I took it apart and I can feed the to the gears but because theres no real tension its not straightening out the filament to get ot the other side. When I visually inspect the feeder I can see the holes arent quite lined up from 1 side to the other.
See Chris' Basement video on loading the filament. You need to open the path up for it to be able to be loaded.
