its worth doing some more research.
these machines were made for profiling jobs not 3d. the control will be analogue.
the big machines have too much inertia for nice 3d work and will struggle with the high code block rate required.
also, do you realise how big this is? probably a 12ft by 6ft footprint. but 8ft by 4ft cutting area. are you sure you need a machine of this size?
