If the feeder casing is white instead of black, you have an Ultimaker 2+. If you accidentally put Ultimaker 2 firmware on an Ultimaker 2+, the feeder will run backwards, because the UM2 uses a knurled feeder instead of a geared one. Update your firmware and you should be all set.

To clarify, it DID work until I disassembled the feeder assembly to clean it (because the tube and the feeder motor gears/thread were just caked in it. I didn't completely take apart the extruder, I only undid the thumb screws so I could disconnect the tube for cleaning.. I am pretty sure I put everything back together correctly. The tension spring and clamping lever are in the correct spots and orientation.. But again, with all that taken off just staring at the base gear, it spins counter clockwise when trying to feed (which actually is unloading!) but clockwise when unloading (which is actually feeding!) But I spent 3 hours trying to fix this yesterday and I am really upset because the other 3 printers we have are makerbot 5th gen and are all horrible.
