Trouble getting all filaments feeding?
I've been fighting setup for a bit and looks / sounds like I have most things correct, but I cannot make the extruder feed the 2 filaments closest to the extruder (0 and 3??). One is free and a filament can easily slide in and out, the other is difficult to get a filament down at all. All filaments are form the same manufacturer and size. When trying to feed the tight side I just get motor buzzing sounds from the extruder.
When looking through the extruder I can see a slight indention on the 2 properly feeding filaments made by the tensioner bearings on the side. The two filaments that aren't feeding have both a full open circle and a circle that is half covered by the tensioner bearings. Is it possible a dimention is slightly off causing feeding problems? Is there a quick fix for this or does it need to be sent back / documented / etc??
Resolved my biggest issue... the set screw was not tightened and fell out when removing everything for fit up on the new bushings. Filaments 0 and 4 feed better now, but 0 doesn't quite move as much as all other filaments when feeding outside of a print. Gotta tear it down again and get the different spacers in. Hopefully that solves everything.
Thanks for the help so far.
