Most likely I would want XYZ and A. But, I'd like the option of
making that XYZ and B - although, in truth, the CNC control
really has no need to know the difference between these. It is really
up to the program that WRITES the G-code to know which linear
axis is parallel to the rotary axis. The controller just moves things
as it is told to.
