3.2 SINGLE DIRECTION POSITIONING (G60)
Explanation
It is always controlled to perform positioning to the end point from a
single direction, for better precision in positioning. If direction from
start point to end point is different from the predecided direction, it
once positions to a point past the end point, and the positioning is
reperformed for that point to the end point.
Even if the direction from start point to end point is the same as
predecided direction, the tool stops once before the end point.
