1.6.4 Selecting the tool radius compensation: G41, G42
Functionality
A tool with a corresponding D number must be active. The tool radius offset (cutting edge
radius offset) is activated by G41/G42. The controller automatically calculates the required
equidistant tool paths for the programmed contour for the respective current tool radius.
G18 must be active.

Programming
G41 X... Z... ; Tool radius compensation left of contour
G42 X... Z... ; Tool radius compensation right of contour
Remark: The selection can only be made for linear interpolation (G0, G1).
Program both axes. If you only specify one axis, the second axis is automatically completed
with the last programmed value.
