This topic as new problem after part transfer to counter spindle.
I have very simple tool motions, but a big part of worpiece disappear, like cutted HUGE TOOL...
For other tool...
And no ANY problem if I define independent workpiece for subspindle.....
we dicussed it internally in our team. Please call GTAC that they open an PR for that. Do you have a chance to test the same in NX10 this would be helpful.
@Ukolov_Dima advise me solution. Problem was in non-zero C axis before part transfer.
