For example, assume that your system installer has determined that you
can perform only two non-motion blocks during compensation. If more
than two blocks following the entry move do not contain axis motion in the
current plane, the control re-performs the entry move at the next block
containing axis motion in the current plane.
Example 15.13
Too Many Non-Motion Blocks After Entry Block
Assume current plane to be the ZX plane.
N1X0.Z0.;
N2G41T0100X1.Z1.; Entry move dresser/wheel radius
compensation left.
N3; No axis motion in current plane.
N4...; No axis motion in current plane.
N5X4Z-4; New entry move dresser/wheel radius
compensation left.
