* These modules are used by all others and are not intended to be directly invoked by the user.
All of the modules require that the probe/bit be located above the reference hole in such a way that a plunge would permit the probe/bit to descend into the hole without touching the Super-Zero fixture. The recess for the reticule must be positioned on the bottom for proper operation.
For safety, the spindle should always be stopped when using the SuperZero - and the probes should never be spun under power.
