Additional commands You can program feedrates and M commands, for example, using additional G
code commands. However, carefully ensure that the additional commands do
not collide with the generated G code of the contour and are compatible with
the machining type required. Therefore, do not use any G code commands of
group 1 (G0, G1, G2, G3), no coordinates in the plane and no G code com-
mands that have to be programmed in a separate block.
The contour is finished in continuous-path mode (G64). As a result, contour
transitions such as corners, chamfers or radii may not be machined precisely.
If you wish to avoid this, then it is possible to use additional commands when
programming.
Example: For a contour, first program the straight X parallel and then enter
"G9" (non-modal exact stop) for the additional command parameter. Then pro-
gram the Y-parallel straight line. The corner will be machined exactly, as the
feedrate at the end of the X-parallel straight line is briefly zero.
The additional commands are only effective for path milling!
