or you have made a 3 axis toolpath and your tool plane for that operation is not aligned perfectly with the Z axis of your Mastercam file

Your output will either come from 'ptlchg$' or 'ptlchg0$', if your Post was based on a Generic Fanuc style Post from CNC Software. If you started with MPMaster, then it's coming from 'ptlchg_com'. There is typically a 'Safe Index' option, for positioning the Rotary, which can be enabled by a variable in the Post, or sometimes hooked up to a Miscellaneous Integer for controlling output at the Operation level. The Rotary Axis in any 4-Axis Post, is output by the variable 'c$'. (Address Label is a function of Variable Format Assignment, regardless of the variable name internally.) Typically, the Post will use 'pcout' or 'pfcout', as the Post Block Call that ultimately outputs the Rotary value. The variable 'c$' isn't used to output to the NC File though. It is for internal calculations of the rotary value. This is due to both "Modality" and because there is an Absolute/Incremental Switch that is typically set by 'mi2$'. Since the Rotary can be output as either ABS or INC, there are different variables formatted for each output type. The variables 'cabs', 'cinc', and 'index_out'. There is a switch that is read typically from the Machine Definition, which tells the Post "the machine supports full rotary", or, "the machine only supports indexing to certain increments". This index increment is typically 1 degree, or sometimes 0.1 degree. So normal rotary output will either come from 'cabs' or 'cinc', provided you are not in Index mode. (There is also a 'force_index' variable switch at the top of the Post.) You mentioned you were running a Horizontal, so I assume you need "B" output for your rotary. A quick way to narrow down the output variable, is to temporarily rename those Format Assignment Strings from "B", to "B1", "B2", and "B3", and then Posting a NC File with several Tool Change events, and check the code.

How I made the two spheres to represent the outside shape and the inside shape. Solid extrude of the letters and Shifter shape from the top view was done to the large Sphere and the smaller Sphere represents the floor to make it look like a closed shape the solid history has everything in it.

I've tested the YG drills and didn't like them. I haven't tried the Nachi Revo drill but I love their flat bottom drills. We mainly use Mitsubishi along with Ghuring to fill the gaps. Kennametal coolant thru flat bottom drills work nicely for counter drilling cap screw holes but they have chamfered corners which eliminates them for a lot of our parts. For a little lower priced coolant thru drill I would recommend Ghuring. They also make nice end mills.
