I recently added CAM to my QCAD 3.4.0 (Linux openSUSE 12.3)
Started by experimenting with a simple drawing (circle and line) to experiment with GCode process.
Selecting CAMExport shows the command in the command window, but nothing seems to happen.
I am moderately familiar with GCode, never used CAM-Expert.
Pointers please to some documentation of some sort.
