Is it giving you trouble when you are creating the tool path or not until you try to run it on the machine?
Are you able to successfully run through backplotting before you post the file?

I'm not familiar with mastercam 9, I've actually been working on mastercam X at school the last couple weeks. I ran into a little trouble today on backplots overlapping on a part, all I did was delete and recreate the toolpath and it worked, I don't know why.

As far as learning mastercam X - I had never used any mastercam until a few weeks ago. I'm quite familiar with autocad, so it was mostly just learning how to find and use the appropriate commands in mastercam.
The manual that comes with mastercam X has two tutorials with it that you can run through to get a little familiarity with it, I mostly learned how to use it by messing around on it until i figured out how ot accomplish what I was after.
I also worked with a tutorial book for mastercam 7, the actual commands don't seem much different - just exactly where to find them and how to use them is a little different.
