I’ve got the X/Y specifics of the Shapeoko drive (stepper/belt pitch/pulley teeth), however looking at the wiki references I’m gray based on the content (or I’m missing it all together). There’s co-mingling of screws, motors and such…
Thank you @WillAdams / @RichCournoyer.
Exactly the references I needed (right here under my nose in fact!)
Specifically, I am setting up alternative CNC controls (non GRBL) in another Carbide Motion controller.
