Duet 3 Main Controller Board - 6HC

Learn More at Duet's Hardware Overview here

See the "Getting Started" guide here

The Duet 3 Mainboard 6HC is a fully featured, high power controller for 3d printers, CNC machines and more. With 6 high current stepper drivers, 4 high current loads, 6 fans and more IO on board it can control many machines directly, with the ability to add much more capability through CAN-FD connected expansion boards.

The Duet 3 family allows for maximum flexibility of machine design through highly capable main boards, expansion boards, tool boards and custom expansion modules. This advanced hardware is enabled by our innovative RepRapFirmware 3 firmware running on the Duet 3 Mainboard and optionally DuetSoftwareFramework running on a single board computer.
