Your geometry might be assuming that the shape is below the centreline.
I think that the rotation radius maybe should be negative (bigger radius = smaller Z height)
I have a similar problem with my manual-B 5 axis setup.
Glad to talk with a master.
About center point, in the machine i am setting 0 @ center chuck.
In sheetcam i need to put positive otherwise it set wrong the working space.
Is there a post processor for standard Plasma table with out rotary? I have Sheetcam and a Commandcnc controller. I would like to use fusion 360 instead of Sheetcam if possible. Thanks
