I don’t see this but I did see one post that refers to 1440 mm which I assume you’re referring to.
I was more focused on the last post that echoes what you’re saying about using 128 mm per rotation:
When you set 128mm per rotation, are you also adjusting the object diameter appropriately? The fact that you’re getting a single rotation with 128mm per rotation makes me think that’s correct. Then you should only need to adjust for object diameter.
