I'm following up on an earlier question I asked concerning a stepper motor failing on a custom made "H" type plotter (Stepper motor failing. Electrical interference?). I now have 18 AWG shielded cable and am about to rewire my machine but I have a couple of very basic questions.
I have two stepper motors driving the Y axis (and it is the far motor on this axis which has been performing erratically). Does it make any difference if I wire the motors as "A" in the diagram below or as "B" with separate leads from the driver? (typo in the diagram: supposed to read "split at rig")
The 18 AWG cable I have has an inner foil wrap plus a bare wire in addition to the four connections. Is it advisable to tie this bare wire to ground at one end of each cable coming from the stepper driver?
