Hi Frank,

They are very interesting cars, I'd like to look at the design in more detail sometime.
I too use SolidWorks on a daily basis. I use Fusion 360 for CAM. Used to use HSMWorks inside SW.
I would suggest not to use an aluminium frame if you are thinking of machining those aluminium parts. Not enough mass or rigidity especially over 1000mm travel.
What's the travel on your X axis? Do have a spindle design in mind?
Regards Simon
