I am building a new cnc router using pacific scientific drives and motors. I'm using a Sound Logic breakout board to connect everything. My P70360 drives have 4 pins for step and direction. Step +, Step -, Dir + and Dir -. Mach3 and the breakout board only have one step and one direction input. Any input on how to wire this would be appreciated.

In the past i have used : http://www.usdigital.com/products/ea/   EA-D10 with the W5 Opt.

That should get you up and running!

Cant you just hook up the output of your breakout board to the + terminal, and connect the - terminal to ground?
Dont know if that would work though

I connected the step- and dir- to the common terminal on my breakout board and the step+ and dir+ to the step and dir terminals. Works great!
