The Duet 3 Mainboard 6XD is designed to allow interfacing with the most common external stepper and servo motor drivers using step and direction signals, with support for 6 external drivers. In addition it provides opto-isolated Input and Output connections for some of the GPIO functions to allow easier interfacing with PLC control systems.
Like the other Duet 3 mainboards it can be accessed directly over the network in stand alone mode (via the Ethernet port) or it has the option of using an SBC (Single Board Computer, e.g. Raspberry Pi) for control. Using the Duet 3 CAN-FD bus it is expandable with the range of Duet 3 expansion and tool boards.
