Im gathering parts to turn my Central Machinery Mill in to CNC. Below is the spects of the driver
4 Axis BIPOLAR Stepper Motor PWM Control
Resolution FULL 1/2 1/4 1/8 Step Mode Individual Axis Selectable
2.5AMP Per Axis with Adjustable Onboard Motor Current
Power Requirement - Min.8vdc to Max 32vdc
Use 4 ,6 or 8 Wire Nema Motor Bipolar or Unipolar
Heat Sinks Provided for All Driver ICs and Power Transistor
PFD AutoTune Feature
Integrated DB25 Breakout
OPTO-Isolated, Motor Driver IC
SMT Components
Dedicated Hardware e-stop / limit screw terminal inputs and outputs

I have 4 motors spects below
powermax II 1.8 step motor
mod.M22Nsxb-JDS-ns-02
Is(dc);2.3 A Bipolar series Vs(dc) 65V
Po 104 W T:90 C max
1500 RPM ambient:40 C
They are 1/4" shafts

The Drive voltage is only rated at 35 Vdc Max. Can i run these motor at that low a voltage ( say 24Vdc) and stay within the current rating of the driver board.

I will also be changing the axis lead screws to ball screw shafts to reudce drag ont the axis.
