orac original stepper drives

Post by Barry_Scott » Tue 17 Jan , 2012 13:15 pm

I am trying to interface a breakout board to the step and direction inputs on the original drives.

Could someone describe what is required.

12v, and if you do a search on here for digiplan there's a circuit describing how to drive the step and direction inputs from a parallel port
