I am using Mach 3, I have everything set up the way I want just to get things going. I am using CNC4PC C11G and some PoStep25 drivers at 24v.

My problem is I can get the enable, and Dir pin to work correctly but not the step pin. the light for that pin wont light up like the others on the bob. I have measured the voltage and with no activity it is at 0.0v and when I travel or jog it gets up to .04v and THATS IT! (others work at 0-5v no problem) Am I missing something?

The steppers move freely with no power and lock up with power applied. Dir pin voltage changes when I change direction. I went to Motor tuning and played with the pulse width 0-5 but no change. I have use a Multimeter to check the bob for these voltages but whenever I unplug the electronics and test the cable directly the voltage never changes, no matter if I measure when I turn it on, start Mach3 or jog. Is that right?
