I am looking to buy a Fadal machine to put in my detached residential garage. I am pretty sure the concrete floor is only 4". Should I stick to the ~5,000# machines like the VMC15 or would a heavier machine like the ~8,000# VMC3016 be ok on a 4" slab?

There will be no other CNC machines operating at the same time. I would have a van in the garage at the same time.

Thanks
