2.4.7 Compensation at inside corners
Intersection
If two consecutive blocks form an inside corner, an attempt is made to find a point at which
the two equidistant paths intersect. If an intersection is found, the programmed contour is
shortened to the intersection (first block shortened at end, second block shortened at
beginning).
