Post Builder - Start of Path Event - Rotary Position Warning

[pracslipkerm]

Hi All,
Does anyone know why I would be getting a catch warning with WARNING: unable to determine valid rotary position after start of path event? I have some face milling and drill cycles on 4 faces sloped at 60 degrees around a rectangle.
The face milling outputs fine even with the error but the cycles don't get the positioning block with spindle start that comes from the rapid_move event. The rapid event is aborting at the beginning - I assume because of the above error...
I've tried switch the tool paths around and each path is fine if outputted on it's own or as the 1st tool path - the problem seems to be on 2nd and subsequent paths. although they call the same procedures.
The catch warning has the csys & machine csys data in it when I check in the debugger...
Thanks in Advance

Cheers

Would the second path posted cause the rotary to pass a limit?
For example if your face mill is at A315.0 and the next path should be A45.0 If your rotary axis settings are axis limits Maximum 360.0 and Axis limit Violation Handling Retract/Re-Engage, this could cause the issue.

Thanks for the thought moudy1,
Got me on the right track - was actually due to B & C axis being switch around, B as 5, C as 4 instead of B as 4, C as 5 as it should be. Also had dual head instead of Head table setup, not sure if this affects anything but fixed it too and now I don't get the error.
Thanks for your help :-D
