Need a sample of a working, proven Mill/Turn lathe with B-axis head, please halp

[jswickJ9PWC]

I'm trying to dial in my post but having nothing but problems. The post isn't respecting plane rotation on the C-axis and is giving me wrong numbers. 

Does anyone have a working example of a post for a mill/turn B-axis that I can use as a reference? All of the sample posts I see are "mill/turn" in the fact that they are turret lathes with live tooling and Y-axis, but nothing B-axis like I need. For reference the machine i'm working on is a Nakamura-Tome NTRX-300L with Fanuc.

Mazak, Okuma, Heidenhain, doesn't matter the flavor since I'm familiar with all of them. I just need to see the correct logic in the post.

Hey J,

Have you looked at the Doosan Mill/Turn post? If I recall, we recently added logic for the SMX style machines, which also have a B axis

Thanks for the suggestion. The Doosan post was outputting the correct B-angle but was still outputting wrong X coordinates. I think I figured it out on my own, though.

This is the issue I was running into--when trying to mill below centerline at an angle, the post would "flip" the C axis and the X coordinates so it was above centerline, even though it would put the B-Axis at an impossible angle. 

This is setup and what I want to accomplish: 

This is the output the Doosan post was giving me:

Ok, still having the issue and this is what I've figured out as to *what* is causing the wrong numbers, but I don't know how to fix it:

Nevermind, got it. Had to enable TCP when machining direction != axial or radial
