Hi Roger,
First I must appologize for my complete newb-ness. I’m nore a designer than an engineer or electrician.
I’m about to try adding a rotary acis as you have done but I was thinking to wire the Y axis in series so that I can free up one of the drivers for the A axis. I’ve seen a couple of different ways to wire this an before I attempt it, I thought I would ask if you knew how to wire it properly. I don’t want my Y steppers to turn opposite directions and lock up my machine. hehe There should be enough amperage for the controller to deliver to both motors through one driver, so I think it would be nice not to have to swap the A axis cables every time I want to use it.
Here are two wiring diagrams I’ve seen so far but not sure which is right for the Onefinity wiring. Thoughts?
