Acu-Rite CNC 3500i user manual 207

Format: G151 T(tool#) D(tool rough diameter) Q2

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.
