4th axis is not rotating continuously

[pcreek]

Hi
I need help in writing a post for my 4th axis indexing table (Chuck). I am programming in Unigraphics NX8 and tried the generic 4th axis UG post. But the 4th axis is trying to go back to zero before start rotating again. Is there any thing I can change in my post to make the 4th axis run continuously without going back to zero again after each rotation of 360 deg. Can any one send me an example of the post. My 4th axis is set parallel to X axis.
Any help in this matter will be much appreciated.
Thanks
Parm

This may be a machine setting....try programming different scenarios to get the machine correct before modifying your CAM

pcreek,
I left out another setting see Pic below.
Click on Option then Advanced Settings (hammer&spanner) then make the setting as I have them.
This should do the continuous rotation for you.
