7.3 Probing Cycles
positioningFeedRate_Normally - set to the feedrate the control will
use while normally positioning the probe around the part
positioningFeedRate_FirstTouch - set to the feedrate the control will
use while making its initial touch to find the surface it is measuring.
dwellTimeAfterProbeActive - for wireless probes, set to the time to
wait after the probe is turned on before attempting a probe move, as
recommended by the probe manufacturer.

for the Tool Length Offset (TLO) or the Workpiece Offset
(WorkOffset).
Spindle Probe Calibration Cycle
This is used to set the effective probe stylus diameter and set the
compensation factor for any run-out of the probe stylus.
You need to have already configured the spindle probe settings per
the previous section.
You also need to have the probe assigned to a Tool # in the Tool
Table, with its 'Type' set to 'Touch Probe', and have it
activate/mounted via a Tool Call.
On machines that do not have spindle orientation or if you
are using a corded probe or cordless UD probe and cannot
orient the spindle 180 degrees during calibration, the
spindle probe stylus needs to be indicated true to the
spindle centerline.
Also, before calibrating the probe with a wired type probe,
the center of spindle rotation must be indicated exactly
over the probe gauge center. In this case the accuracy of
the spindle probe is only as good as the stylus
concentricity to the spindle and the closeness to the probe
gauge center. Calibration must be done at least once
before using the spindle probe. Once calibrated,
calibration does not have to be done again unless you
replace the probe stylus.
