What axis is the 4th axis around ?
Your machine definition is for a 6 axis, XYZ & ABC
what is the "NEW VIEW " ?
- it must be a legitimate view of any scene when rotating around the 4th axis
your post is trying to rotate C axis to place view8 in respect of the TOP VIEW
- this will happen even if you are 0.00002" out of rotation
Suggest you revisit the WCS and the T&C planes you are using on this part
-the WCS that you use, is normally the TOP view of any setup,
- T&C planes around the X axis will give A outputs - this is standard for a 4th axis along the X-axis
- T&C planes around the Y axis will give B outputs, B0 view is the working view of the part that is seen from the tool, for a horizontal this is the FRONT VIEW, where RIGHT VIEW gives a B90 output etc
