Swivel of B axis > 90¦

[grisel360]

I am using Mastercam to promgram a SIEMENS DMU50 5 axis (3+2). This machine is able to rotate at:
- C axis (z) 360° max and
- B axis 105° max

Eventhough, if I postprocess an operation that requires to rotate:
***B=90.41 and C=180.008***
My mastercam post throws this:
CYCLE800(1,"DMG",0,27,0,0,0,180.008,0,90.41,,,,1)

But machine is not able to reach any B angle higher than 90° with this kind of code (is able at manual mode), I mean with:

CYCLE800(1,"DMG",0,27,0,0,0,180.008,0,90,,,,1) works perfectly, pero.....
CYCLE800(1,"DMG",0,27,0,0,0,180.008,0,90.41,,,,1) fails

Cant understand why the order of A,B,C's grades is exchanged after postprocessing and it still works, anyway with something bigger than 90° doesnt...

I've found before excellent answers to CAD questions from very experienced people at this forum, please help me on this one!
Thanks
