Extruder Motor Not Moving

I have my extruder motor plugged into E0. It will not manually feed filament or feed when i try to print when it is hot or cold. The motor will move when I plug it into the pins for the X or Y steppers. I’m using an MK8 extruder from ebay, and everything else from here.

I know this sounds obvious, but do you have a stepper driver for the extruder on the board?

If there is, is it in the correct orientation? Any idea what the current limit is set at?

Yep, that was it. I need a stepper driver. Thanks!
