You can go to utilities and info to find out what version of c6 is on it. Sounds like it has been upgraded.
I had to replace the ballscrew bearings on my vm 17 when I got it. 7204 angular contact bearings off Ebay 2 per ballscrew, and 6204 ball bearings 1 per ballscrew less than $100 for everything.
I use bobcad cam. I have a post processor that should work for your p1.
