Hello,
I am building a crane-like 3d printer and I would like to configure smoothie's kinematics similar to this: …/kory75/Marlin_360 on Github (I can't post it as a link, please reverse the pieces:)

the difference is that in my case the print bed is not moving and instead of the 'y' axis the 'x' axis is rotational.

So let's say that I start with the Cartesian style kinematics. How can I make the 'x' axis rotational?
