I think I can help. I got these:
Are any of them any good for you? is so PM me please and I'll E-Mail them.
I'm running a Protrak A.G.E 2 with an MX2 Post so I dun know if the MX3 Posts is the same directory will work, but I think they should?
You say that you "cant seem to get anything to work". When you go to Post Process how far does it get? Any error messages? On mine it sticks the Post Processed file in the C:\MYDRAWINGS folder, I need to rename the file numericaly (like 12345.CNC) for the Protrak to recognise it when I transfer it to the Mill- it won't recognise alpha characters, only numbers as a file name.
Gimme a shout if you want the files!
