Page 24 of 63 April 2019 • 23 NEWS SCOPE MUDBOTS 3D PRINTER MudBots engineers characterize the 664 as a work envelope-optimized cartesian printer powered by IP65 direct drive NEMA 34 hybrid stepper motors. They run in a servo loop controlled by field-programmable gate arrays and administered by LinuxCNC (computer numeric control) running on a real-time operating system. The elements combine to form a low jerk, high payload system with repeatability > .1 inches. Engineers fully integrate the mixing and concrete delivery platform into the LinuxCNC, allowing operators to load the extrusion nozzle material with on-the-fly flow rate and outfeed pressure control.
