Z axis doesn't go up need help asap!

X-Carve Troubleshooting
1

So I was carving another one of my trays I do and the z axis stopped going up. I did this exact same carve a few days ago and no issues. I just checked all the wiring, took x controller apart and made sure the dip switches are correct and they are as pictured in instructions as 1 is down, 2 is up, 3 down and 4 up. http://x-carve-instructions.inventables.com/photo/newdips.png
I checked the wiring and it is all secure. I blew out the motor and lightly lubed the pulley. what is causing this? here is what it looked like when doing the second carve.
