vRef Problem

[ianober]

I was checking my vRef settings on my pro board and the X and Z axis' were fine, but the Y axis I cannot get higher than .20 volts (1.45 amps~). I am running 200 oz. stepper motors from HobbyCNC and they are rated for .42 vRef or 3 amps. Not sure where the breakdown in the board could be, has anyone else run into this?

Nobody's had this problem or any ideas?
