Fusion 360 CNC Boundary


I am having issues with the Run boundary on my Snapmaker.

As you can see in the images below, I set the size of my stock I will put on the Snapmaker and set the origin point to the middle left.

When I run a boundary check the too path runs along the left edge then across, like it has no idea of the stock size. when I start the job it is all in the correct place.

Has anyone else seen this?
