The Duet 3 Expansion board is a CAN-FD connected, high current, full-featured expansion board for the Duet 3 Mainboard. The Duet 3 family provides control for a wide range of machines including 3D printers, CNCs, laser cutters and more, building on Duet3D's experience in developing the most flexible and expandable 3d printer control solutions. 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.
See the documentation links below for a full feature set.
