Since Version 9 is a major release posts that have been written for earlier version must be updated to insure proper functionality and safety. If a Post from a previous release is used Mastercam will issue a warning to the user with instructions to run Update PST. This function is found under the NC utils, Post processor menu.

The post question list files (MILL8Q.PST, LATHE8Q.PST,
WIRE8Q.PST) have been updated and renamed for release. The new names for these
files are Mill9.PNQ, Lathe9.PNQ, and Wire9.PNQ. PNQ = Post Numbered Questions.
With some simple changes to the post it is now possible to out put full circles as a single 360 arc move instead of two 180 moves. Refer to the Post update documentation below for details.
All new post
information specific to Version 9 is documented in a file called Post
Processors - What's New in V9.PDF. This file is installed in the root directory
of Mastercam 9, by default this directory is C:\MCAM9.
