Each operation can have it's own feedrate. In the OP you have Feed (XY cutting) and Plunge Feed (Z cutting. Mastercam will average that for 3 axis cutting.
Where did you get your post?
Did you just update to X3?
There was a known problem with the MPMaster post outputting zero's for feedrates when it was updated to X3. Search this forum for additional information.
