Hey Bill, thanks again for the tip. I created a new configuration, changed the port setting, motor tuning & backlash settings and it works absolutely great!.
In a nutshell for others who might be trying to accomplish the same thing:
I configured the output ports so that the controller output for the 4th axis stepper was on the Y axis port.
I changed the motor tuning on the Y axis to match my 4th axis, changed the Units per my previous post.
I configured the output ports so that the controller output for the Y axis stepper was on the A axis port.
I changed the motor tuning on the A axis to match my Y axis, changed the Units to match the Y axis setting used in the conventional mill mode.
Unticked the A axis Angular setting
Changed the Hotkeys so that they worked as in Conventional mill mode U/D arrow keys controlled the remapped A axis (Y axis), and my Home/End keys control the Y (A rotary axis) this prevents any jogging crashes when going from Conventional and Rotary Mach configurations.
Changed the Motor Reversals as required for the proper direction.
Created a new Profile & Shortcut Key for Rotary Configuration.
Now, no matter what I do in my CAD/CAM software the posted code needs no changes, I can perform the operations in either the Flat 2.5D environment or the rotary environment by simply selecting the Appropriate start up Icon. All my posted code remains the same. The only other setting I have to change is the Units setting & backlash for the diameter of the part I am working with.
Pure Mach Nirvana!!!!!!!
