Mid operation spindle direction change

[chattygt]

Hello. I am using the supplied mplmaster post for mastercam x5. I have modified it for our machine (2 axis lathe fanuc ot control).

 

I am stuck on why it is doing what it is doing. Using the same tool for some reason during grooving or part off it wants to stop the spindle and change direction.

 

My tools are set up correctly. I am using the same tool to groove, plunge turn, and part off. The tool should be using the M04 (CW) on all operations.

 

I have tried using the post debugger to make sense of what is happening, but I haven't had much luck.

 

Here is my code, let me know your thoughts, or if I am missing something.

 

Thanks in advanced.

What if you change default active spindle to "right"? Does the spindle direction change and everything else stay the same?

This is what it outputs if I change my default spindle to "right". Similar issues. I was thinking it may be coming from the "finish" spindle speed settings in the tool path.
