Oh nice tip, thanks. I don’t have limit/home switches but could twist the stepper wires into pairs. If it persists then I’ll give it a go.

Right now I’m battling a new issue - as soon as I had the X and Y axes wired up and working, mach3 decides to begin acting strangely (will jog fine, but will not move these axes when running Gcode). At first I though it HAD to be something to do with how I had wired it up as that was the only change, but my mach3 profile works fine with on another computer I tested. Almost finished… hopefully.
