The reason why you cannot find any documentation about this is that
CAM Expert does not directly support any type of specific commands
or formats (including G-Code).
CAM Expert outputs whatever is configured in the machine configuration
file (.cxm) which is used for the CAD -> CAM conversion. If there are
any G40/G41/G42 codes in there, they will be output to your file.
In fact you can output anything to the CNC file.
I.e. CAM Expert does not know or understand G-Code or any other
machine languages. It simply writes whatever is configured in the
.cxm file, be it G-Code, HP/GL or any other file format or language.
CAM Expert can use tool offset corrections under the following condition:
- All contours are closed and have the same orientation (clockwise
or counter-clockwise). Note that CAM Expert can automatically reorder
all closed contours in one or the other orientation (see CAM export dialog).
If this is the case, you can simply output a static G41 or G42 in
the order that starts a new contour (OrderContourStart) and a G40
in OrderContourEnd.
If your drawing is more complex than that, you might want to split it
up in a drawing that contains all CW contours, one with all CCW contours,
one with all open countours, etc.
