Please Help - Z-Axis Quit working - Melzi

I ran a print last night on my i2 it printed fine. When I went to home the z axis before shutting everything down it wouldn't move. I've tried everything I can think of since and nothing I try works. I flipped the y and z to check the motors and they are all fine.

Melzi v1 with Marlin firmware
