@dc42 Is there any update to this. I also want to look at a retrofit CNC application and I need step/direction output. I really wish there were at least pads on the PCB for this even if no headers. I'm an EE so I assume I can scope/find them on the input side of the stepper drivers, but that's a PITA. Is there no one board solution as of now? If not I'll go ahead and grab the Duet3 Mini and just break out the Step/Dir myself.
