ERROR - AXIS SUBSTITUTION IS SETUP FOR VMC WITH +Z ZERO POSITION

[neurosis]

Can anyone tell me what this error means?

I'm roughing the face of a large ring using axis substitution.  Typically I'll just unroll all of the geometry and drive the tool path using the unrolled geometry. Since this is all perfectly spaced around the face of this ring I decided to try to transform the tool path to save some time. 

I'm using a version of MPMaster that is relatively up to date (meaning I've updated to the latest version from the forum and used a file compare util to make the changes we've made over the years). If I install a Fanuc post and machine def from the tech exchange I don't get this error.  I assume it has something to do with the way the machine definition is set up?

They are definitely set up different.

Yeah that setup has changed X & Y have always been part of the Table group with A or B, if it existed, set on top of those.

Well, ticking this in the transform operation made it postable without the error. It added a weird WCS to my planes but who's complaining?

In my experience, that "include wcs" button is for when I don't have TOP as my main WCS plane.
But I'm no expert in axis sub by a long shot.
