G43.4 on NTX2500 CELOS

We have a new NTX2500 with Celos/Fanuc 31iB5, I am programming with Featurecam and we have a post supplied by Autodesk.

I am going through it proving the post out, and so far it seems solid, just a few very minor tweaks.

Today I tried a simple 5 axis simultaneous path, machining a tapered hole with an endmill with a swarf toolpath. Problem I'm having is that with G43.4 enabled, it seems to move correctly in X-Z-B, but not in Y-C. Visually, it looks like C is moving about the right amount to follow the toolpath, but Y distance is somewhere around the actual coordinates in the program, i.e very little Y axis movement, and not following C properly.

Full code is a lot of lines, I trimmed a whole lot of it out of the middle to post here.

Anyone know what might be going on?

In case anyone else ends up here with the same question, the machine was set to "Workpiece Coordinate System", when it was required to be in "Table Coordinate System".
