Filament won't go through feeding mechanism

[ryanbordner 0]

I had been having extrusion problems so I disassembled the feeding mechanism to see if anything was clogging it up. When I put it back together and screwed it back in, the filament would get jammed up before reaching the feeding mechanism. It doesn't seem to be aligned wrong but I don't know what else to try out.

Any ideas?

Did you mix the direction of the bowden tube? The one on the feeder end has a 45 degree bevel on the inside of the tube so the filament is guided into it. The nozzle end of the tube is just straight. If you mixed them up there's a chance that the filament will just hit the edge of the tube and stop.

I'm assuming it's an UM2? If so, did you perhaps accidentally put it on backwards? It's easy to do (not that I've ever done it myself or anything... ).
