Hi,
I am milling a flat onto the end of a diameter on my Mazak 250MSY. It can be milled using the Y axis because it is within the limits but for some reason the C axis is indexing to different positions between 2 operations. The program simulates fine on Fusion but on the machine the flat from the roughing operation is not aligned to the flat in the finishing operation. I am using 2D adaptive for roughing and 2D contour for finishing. At the moment i am just forcing polar mode to get it to use the C axis instead which fixes the issue, so i think it has something to do with the post with how it handles the Y axis and the C axis indexing when Y axis is active.
Heres two snippets of posted code from both operation showing that it's indexing the C axis incorrectly on the 2D adaptive tool path.

M9I have attached my post processor, its nearly default to the one supplied by fusion but have made a few edits to do with sub program calls etc.
Thanks
