Re: [CAD_CAM_EDM_DRO] Litton shaft encoder

It's arbitrary (sort of).
If the motor immediately faults when a step is applied, then swap either
the A+B phases, or the wires driving the motor (depending on whether the
motor spun in the expected direction or not).
As long as the "polarity" of the encoder wires matches the polarity of
the motor drive wires, you should be all set.
