Welcome to the Wiki for the Duet 2 (Wifi, Ethernet Maestro), Duet 0.8.5, and the Duet 0.6 - a family of control boards for 3D printers and other similar robots. These control boards are based on a 32-bit ARM processor, running RepRapFirmware. The Duet family can all be controlled through a web interface, but they also support a touchscreen called the PanelDue. They all have a connector for an expansion board containing additional stepper drivers and I/O circuitry - the Duex 2 and Duex 5 for the Duet 2 (WiFi and Ethernet), and the legacy DueX4 for the Duet 0.6 and 0.8.5, and
