Well, there usually is not a huge reason to have home
switches on a rotary axis, unless you have setups that will
be reused on following days. So, you can set the A to home
wherever it is (search and latch velocity of zero). Ground

LinuxCNC to think the axis is moving without command. Then,
you can even unplug the axis while LinuxCNC is running, and
plug in the shorting plug.
out of the logic that determines whether the machine will run gcode when
that A axis has not been homed because its unplugged, off the machine
and stored and either is unhomed, or was never homed since this power
How is this best done? Preferably done so that a powerdown to switch its
homing on or off, won't disturb LCNC's ability to run gcode just because
the A isn't homed??
Another scheme is to have two LinuxCNC config file sets, one
with the A axis and one without.
