RAMPS 1.4 to big drives

I have an older home built gantry machine that hasn't been used in years. I would like to use it for large format 3dp. I used to run Mach3 but would like to use a RAMPS board to control it now. Would it be possible to get step and direction from the RAMPS to this Rutex Servo Drive ? Pin out starts on page 5.

Thanks,
Kevin

Hi Kevin,

check, if the STEP+DIR inputs are defined for +5V ...

The drives are meant to be run off a pc printer port. The way I understand it they get +5 to the pulse and dir pins.

Thanks,
Kevin

I think I figured it out. I tried hooking to the drives Sat and got no result. I checked for a pulse with my graphing multimeter but dc wasn't working so I wasn't confident in the voltage readings. I brought ut to work and hooked to a scope. I was only getting 50mV with usb power. I gave it 12 volts and now I get nice 5V squares.
