4th axis post question

[WingNutz]

Good Morning Gentlemen,

I am editing the generic fanuc 5x mill post and my angles are slighty wrong. First, let me explain my setup. We have a 4th axis (B axis) mounted on the X plus (right, when facing machine) side of the table. The 4th axis is limited on travel. When facing machine, the B axis can move away from operator to B+90 and towards operator B-120. My problem is when I program to rotate to B-90 it posts out B+270. Theoretically, this is the same position but with my limits I can't rotate 3/4 turn. Thanks for any and all your help.

I was able to fix my post so that the proper signed angle is posting.
