I've just had a look at these sites. Quite interesting. I like the 3D CNC Printer. Plus that CNC certainly seems to be biting a big chunk out of the aluminium on each pass. Have a look. https://www.stepcraft-systems.com/en/ And Stoney CNC, from small stuff to really big stuff! http://stoneycnc.co.uk/stepcraft-840-cnc-route-system/ Gray
Nice find gray. I like that z design. It addresses some problems. Overall, looks like a well thought out hobby machine.
