10.4 Changing direction of compensation

10.4 Changing direction of compensation
A perpendicular vector with length R is created in the appropriate direction of compensation at
the end position of the block with the old G function (G41, G42) and at the starting position of
the block with the new G function (G41, G42).

Changing offset number (D..)

When the offset number is changed the following applies:
No block start intersection is calculated with the old compensation: a perpendicular vector with
length R1 is created at the end position of the block with the old offset number; the block end
intersection is calculated with the new compensation.
