I do foam and alu milling. What I really like with MadCam is that I do all work in Rhino and that's it, and the path's are really reliable. If you make a change in your model you need to reprocess the path's. I don't see that as a major issue though, it's quite fast.
About the controller, send an e-mail to Joakim directly and he weill help you with that. He's pretty busy, so be patient.
