Designed for machines which require external stepper motor drivers or servo drivers, the Duet 3 Mainboard 6XD is a powerful, fully-featured controller. It has similar inputs and outputs to the Duet 3 Mainboard 6HC and supports up to 6 external stepper/servo motors. The Duet 3 Mainboard 6XD does not have any built-in stepper drivers.
The Duet 3 Mainboard 6XD also has opto-isolated signal outputs to integrate with a wide range of industrial control systems.
The Duet 3 range of products aims to provide maximum flexibility through expansion boards, tool boards and expansion modules. This modular expansion is possible because of the innovative RepRapFirmware 3 running on the Duet 3 Mainboard 6XD.
