Well, progress. My younger son, who's just started FRC last year as a freshman, took an Inventor Pro File that had been graciously converted by RC to run under MasterCAM, and got it to run in the machine on a chunk of wood. Following several suggestions gleaned on-line we're picking up some carpet tape and will try to cut the piece out of aluminum during a Sat. summer build session.

I'll let you know how that goes.

Thanks again to the FIRST community for all your help.....
