With T, D, and Q cycle parameters set:
 The machine rapids the Z-axis up, picks up the tool designated in the
T cycle parameter, and rapids directly over the center of the probe
stylus.
 The Z-axis rapids down the distance placed in the
ZRapidToStartPositionFromHome machine setup parameter then
starts feeding down toward the probe for the initial touch at the
feedrate that was placed in the ZFirstPickFeedRate_Fast machine
setup parameter then backs up.
 The machine rapids over half the diameter of the cutter from the
probe stylus center in the direction related to the probeOrientation
machine setup parameter.
 The spindle then comes on counter clockwise at the RPM specified
in the calibAndToolMeasurementRPM machine setup parameter
and retouch the probe twice, once at the feedrate that is in the
ZFirstPickFeedRate_Medium machine setup parameter and again at
the ZFirstPickFeedRate_Slow machine setup parameter.
 The tool-length register for that tool is now updated, and any value
in the length wear register is reset to zero.
 Then the Z-axis rapids up above the probe stylus the distance
specified in the ZRetractAmount machine setup parameter. Then it
rapids the X & Y axes over the center of the probe and turns the
spindle on in reverse.
