Product Description


Duet 3 Mainboard 6HC

The Duet 3 Mainboard is a next generation controller board that builds on Duet3D's experience in developing the most flexible and expandable 3d printer control solutions. It is the core of the Duet 3 family which provides control for a wide range of machines including 3D printers, CNCs, lasercutters and more. The overall aim with the Duet 3 series is to allow for maximum flexibility of machine design through highly capable main boards, expansion boards, smart tool boards and custom expansion modules. The flexibility of configuration and advanced features are enabled by our innovative RepRapFirmware 3 running on the Duet 3 Mainboard and DuetSoftwareFramework running on a single board computer.
