    Pay attention to the inductance of the steppers. I didn't do that when I purchased mine. My 270oz motors had a little over 5mH inductance and really needed 70v to run them to full potential. I'm only pushing 48v into them with no problem so far. Since you're using two motors to power your Y, you might not need that much torque on those two motors....just a thought.
