David, I put in attach with this reply your post.
I create a rule in pst that when you have a move only in Z, put only FZ, when you have a move only in X or Y or both, put only FX, and when you have a 3 axis moves (XYZ) or X or Y move combined with Z (XZ OR YZ) the post put FX after X/Y values and FZ after Z value.
Try and report to me your results.
