CAM Expert software

Hi Group

I was wondering if anyone has used CAM Expert by Ribbonsoft. We are
building a 4x8 gantry for plasma cutting and need a simple drawing
and CAM program. I have E-mailed the site a couple of times with no
response so I a bit nrevous. It seems to work well (the demo) but I
haven't figured out how to do kerf compensation.

If not this software what would you all reccomend to use as a drawing
and Cam software. This needs to be as simple as possible so the
machine can be used with minimal training.

Thanks
