Could be your rotary table is moving A positive and A negative in a different direction than your post is posting. Is the cut direction correct? (climb cut is actually a climb cut on the machine?)
If this is the case, then a simple post edit changing the A axis direction will fix it.
Now that I re-read what I wrote, I guess I am assuming you've never posted a program for this machine setup...If you have posted before and it rotates the correct direction, then perhaps I am missing something...but I can't open your file since it is X6 and I haven't installed 6 yet.
Oh, and btw - welcome to the zone
