 I switched to some linear encoders that have a D-sub connector. They are also 5V differential output, and nearly the same resolution, resulting in very easy switchover.

 Three enables are used - one for the X and Y axes, one for the z axis, and one for the spindle. This allows the z axis to be disabled independently for manual drilling operations.
