I've encountered an odd behavior when trying to post two sequential toolpaths (using the PocketNC Post Processor) in orthogonal directions, the first starting at A90 B0 followed by A0 B-180. Fusion will fail to post two toolpaths using these tool orientations, but if you add an intermediate toolpath in a different orientation, like A0 B0, it can post all three without a problem.
I've put together an example here: https://a360.co/2qIz0MX
There are three setups, only one of which works. I tried injecting some manual gcode between the two problematic toolpaths (going to A0 B0) into what I was posting, but because it is passed-through I don't think Fusion is considering the intermediate machine orientation, and still failing to post. My uneducated guess is that there's something like an internal gimbal lock condition happening.
Has anyone else seen something like this, or can trace through the post logic to confirm?
