To calibrate the tool probe:
Jog the calibration standard (the calibration standard should be in
the spindle) to the top of your work piece or a common surface
where all your tools will be calibrated to, and set its tool-length
offset to the top of the work piece or to wherever you would like
your Z zero to be.
To calibrate the tool, jog the tip of the calibration standard to the
proper spot.
Touch the Teach button.
Manually jog the calibration standard over the probe stylus center
and less than 0.1" (2.54 mm) above the probe stylus. It should be no
more than 0.1" (2.54 mm) from the center of the stylus.
From the Manual Data Input Mode with G-code MDI selected, type
G150 D(n), and touch the Start button. Where D is the exact
diameter of the calibration standard.
The Z-axis initially goes down and touches the top of the probe
stylus at the feedrate specified in the ZFirstPickFeedRate_Medium
machine setup parameter. Then retouch at the slow feedrate,
specified in the ZFirstPickFeedRate_Slow machine setup
parameter, establishing the zero probe stylus top.
Then incrementally rapid up whatever value that is in the
ZRetractAmount machine setup parameter.
The spindle comes on at the RPM specified in the
calibAndToolMeasurementRPM machine setup parameter and then
the calibration standard moves over an incremental amount that is
equal to (Half the value entered in the D cycle parameter + Half the
value entered in the nominalProbeStylusDiameter machine setup
parameter + The value in the XYRetractAmount machine setup
parameter). The direction the probe moves over depends on what is
placed in the probeOrientation machine setup parameter:
Example:
-1 Go first to the left
1 Go first to the right
-2 Go first to the front
2 Go first to the back
