Might be a post issue. Have you tried checking with a generic machine definition? I see the Machine Defined by Update Post.dll which tells me you are using a very old post and the support needed for X7, might be the issue in that old of a post. Using a Generic 4 axis Machine and Post I got the following output not using depth of cuts.

I think I found the problem I turned on rotary axis positioning and it seemed to work does this make any sense

 

Nope because you used TOP WCS as your WCS in all the operation and the T/C-Planes to control your rotations. By doing that you are really pointing ot a post issue and not a operation or Mastercam issue.

thanks I will have to study this some more to understand I am still green when it comes to rotary work

 

I will say you approached what you did the correct way. I see it is a HAAS Machine so might look at the X7 HAAS machine and see if it gives you the code you need if so then I would seriously think about using a X7 Machine and Control Definition with X7 post.

 

Glad to help out.

Did you look at my example code? It posted the A0 with the operation using a Generic Machine. If you are not getting that output with this type of operations setup I am sorry to say I think it is a post issue and with using Axis Sub you may be tricking the port to give you output, but in my humble opinion it is not the correct way to go about doing this type of work. Bad Habits are very hard to unlearn and getting in the habit of tricking Mastercam because of a post issue starts you down the wrong path. Again take it for what it worth.

thanks again for your help.I,m not sure where to begin to fix this issue this is the post we have always had so you were right in saying it is an old one.We have just gotten used to working around our problems instead of fixing issues,just the way it works around here some times

Yeah well seen that more often than I like and like I suggested look to the machines that installed with your X7. There is a Generic 4 Axis HAAS Machine Load it and post code from it. Compare the code from what your post is giving you. If they match you are golden, if they are different then how are they different? Does that code make a good part? If no why? If yes then why make it harder on yourself if you don't have to?

also I meant axis positioning not substitution not that it might matter

 

I have a manifold I am doing with 270 operation with many different indexes in it. I program it like you did in your example and always get the output I need without having to use that. So again no in my opinion it does not matter. Have you bothered to reach out to your local Mastercam Dealer to see if they can offer you some insight? You might just be surprised how willing and helpful they can be.
