7.3 Probing Cycles

Field	Code	Description
OvrSlw	S	This is the override for the slow feedrate
Feed		that was set in the machine setup
		parameter ZFirstPickFeedRate_Slow. This
		is used for the same reason as the M cycle
		parameter. This can only be set slower.
		Trying to set this higher will result in the
		software using the original feedrate.
		(Optional)
OvrRPM	R	This is the override for the RPM that was
		set in the machine setup parameter
		calibAndToolMeasurementRPM. This is
		used for the same reason as the M cycle
		parameter. This can only be set slower.
		Trying to set this higher will result in the
		software using the original RPM. (Optional)

Large tools can result in probe damage if the feedrate is set too fast. For this reason, the cycle parameters: M, S, and R have been added to enable the programmer/ operator to override the values in the machine setup parameters for the specific tool being checked or set.

Running this cycle without first initially setting the length and diameter offset could result in damage to the probe and/or the machine tool. G150 Calibration and G151 Automatic Tool Length and Diameter set, or G152 Manual Tool Length Measure for Special Tools and G153 Manual Tool Diameter Measure for Special Tools, must be run first before using the G154 cycle.
