Second to fourth reference point return (G30)

Format
G30 Pn X... Z... ;
With the commands of "G30 Pn X(U)... Z(W)... (C(H)... Y(V)...);", the axes are mo-
ved to P2 (second reference point), P3 (third reference point*), or P4 (fourth refer-
ence point) in the simultaneous 3-axis control mode after the positioning at the spe-
cified intermediate positioning point. If "G30 P3 U--40. W30.;" is specified, the X-
and Z-axis return to the third reference point. If "Pn" is omitted, the second refer-
ence point is selected. The axes not specified in the G30 block do not move.
Reference point positions
The position of each reference point is determined in reference to the first refer-
ence point. The distance from the first reference point to each of the reference
points is set for the following machine data.
