What i need to know is what input are they expecting.

+5v +12v +24v

how much current is required.

is there a difference in how they process the incoming signal?

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

Could someone describe what is required.

Hi

I am looking for an Orac machine to retro fit and modify. I am not interesting in working electronics just solid mechanicals.

Thanks matt
