Hi Guys

I need some help with my Post Processor. Its for a DMG MORI CTX310 3-axis Lathe which is mainly X,Z, and C axis. That's the Sinumerik 840D Control. I have a Machine post processor for Mastercam 2019 that I have received from world skills International that is locked. I created all my toolpaths correctly (checked by generating the code on Generic Haas 4XT Lathe Post), but when I try to generate my code, it comes up with an error saying Y-axis motion encountered. This is from the Mill-turn operations.

I then converted the post to mastercam 2020 and was able to generate the code but with a Y-axis value output.

Any ideas on how to change it to use C-axis without editing the actual the Post files?
Or as a last case scenario is it possible to somehow unlock the post?

Thanks I appreciate your immediate responses.
