4th Axis Program.mcam This program simulates correctly but on post and at the machine the drilling in some areas comes up short.

Thanks. Getting one ready

I am really lost here....I for one do not have much experience with rotary programming and only a few years with mastercam Mill programming so be gentle. My issue is every since an update a few years back with mastercam something changed with 4th axis rotary programming and I am struggling with hole depths that simulate correctly but at the machine or in the post itself the depths do not reflect what the program is telling it?? I have exhausted myself with what little knowledge I do have and need some guidance. I also recently had a part that all the holes were to be drilled to the same point (round cavity) and had all kinds of issues with my depths all being different? even retracts were all over the place. Is this a post update I missed during this update? I would appreciate any advice. Anything that you can help with is greatly appreciated. Thanks
