Bad post?

[So not a Guru]

I am hoping someone can help here. We have a Mazak Variaxis i800 with a Postability post. The post has been working well for us for years, with an occasional tweak being needed.
Our other 5X machine is down, so I had to reprogram a part to run on this machine. Ive attached a zip2go.
At the start of the morph toolpath the machine is attempting to move to a point that appears to be 180° from "X"
, which would plow thru the vise. I've never attempted this 4 axis path on this machine before, but if I change the tool axis control to 5-axis fixed angle to axis Z, it outputs close to the same code.

In the image I've hidden one vise jaw & shown the path that the machine is trying to follow. The red marking is where the path should start. The green marking is where the path is trying to start

Is this a post issue?

Nevermind. It turns out I just don’t have any faith. The toolpath was going to the correct spot, but my starting point needed to be further away in the Y axis. When I repositioned the start point it ran correctly.
