I am always skeptical about those max print speeds. The Stock MPCNC can handle 197mm/s but none of my 6 printers can print parts with any strength over 35mm/s. The prints look good, some of them get ringing worse than others but they all have very poor layer adhesion. The only way I know to truly speed up printing is a larger nozzle.
Yup you can make your legs go into your table to make an adjustable MPCNC. That is why the feet bottoms don’t have bottoms. Give it a try for the best of both worlds.
