1.2.18 G37: AUTOMATIC TOOL LENGTH
MEASUREMENT - I
Command form:
G37 Z_ [R_] [D_] [F_] [P_] ;
Z: Absolute command for end point of Z in program coordinates.
R: Measuring distance, incremental value from Z position. Value of
Pr4055 will be used if R is not defined.
D：Probe overtravel distance. Value of Pr4056 will be used if D is not
defined.
F: Measuring federate. Value of Pr4057 will be used if F is not defined.
P: Reference point P. Value of Pr4058 will be used if P is not defined.
This action of reference point return will not be executed if Pr4058 is
used and is not set 1~4.
