Printrboard running E uncontrollably, and Y not running at all.

Hi, I've had a Printrbot simple for about 6 months now and I am starting to have some issues, My Y axis does nothing when under manual control, it only moves when being homed. However, the strangest thing happens when I start the print. It reaches temp, homes the axis, then the E axis goes extremely fast, the Y doesn't move at all, and the X moves just a tiny bit. I have reflashed the firmware, and have tried a different computer with Repetier Host. Nothing has helped at all, if you could help me that would be great. Thanks in advance. Here is a video of it. https://www.youtube.com/watch?v=AAuvoRLo6z8

Are you sure you didnt switch those two at the motherboard?

You could always try switching them and see what happens, As its kinda clear as your Y only moves a tiny bit wich the E should do, and the E is pretty fast, again what Y would suppose to do.
