The X and Y axes work just fine, but the Z axis doesn't move. I'm using a Folger Tech Prusa i3 Acrylic.

Has it ever moved? Have you changed the motherboard type in Marlin (configuration.h) to 33?

Try set the vref on the stepper a little bit higher.
Lower the z-axis speed and acceleration in marlin.

I've already tried up to 0.480 V on the vref with no success. I'll test the speed stuff.

Nope, it's never moved. Yes, the motherboard is set to 33 in configuration.h
