Welcome to the Wiki for the Duet 3, Duet 2 (WiFi, Ethernet and Maestro) and legacy Duets (0.6 and 0.8.5) - control boards for 3D printers and other similar robots.

These control boards are based on a 32-bit ARM processors, 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 expansion capabilities, for additional stepper drivers and I/O circuitry. Duet 3 expansion is via the CAN-FD bus, and can connect to multiple Duet 3 Expansion and Tool boards. Duet 2 and legacy Duets have a connector for an expansion board. For the Duet 2 WiFi and Ethernet there is the Duex 2 / Duex 5 and the Duet Expansion Breakout board (for external drivers). For the Duet 2 Maestro there is the Dual Stepper Expansion. For legacy Duets there is the DueX4. See the relevant Duet Hardware section for details.

If you have a Duet 2 Wifi or Duet 2 Ethernet please see the Step by step guide to using your Duet 2 to get started.

If you have a Duet 2 Maestro head to the Maestro documentation

If you have a Duet 3 please go to Getting Started With Duet 3 MB6HC

The firmware for the Duet family of boards is open-source, but most users should not need to modify the firmware itself, only working with settings stored on the internal SD card. Nevertheless it is a good idea to update your Duet to the most recent stable firmware.

• Where to get Duet firmware, software and drivers
• Contributing to firmware development

There is also a fair amount of information about the firmware http://reprap.org/wiki/RepRap_Firmware including a http://reprap.org/wiki/RepRap_Firmware_m....

• Installing and Updating Firmware

RepRapFirmware is highly configurable so it needs to be setup for your specific printer to work. Considerable customisation is also possible, It is recommended to read the Cartesian printer section below even if you have a Delta or CoreXY as there is general information there that is applicable to all printer types.

Any 3D printer needs a certain amount of tuning to perform at its best. Most of that tuning is not specific to a particular set of electronics, but the Duet electronics offers additional possibilities.

• Calibrating a delta printer
• Mesh bed compensation
• Firmware retraction
• Pressure advance
• Multiple tools and Tool change macros
• Setting motor currents
• Setting acceleration, jerk, and maximum speeds
• Compensating for extruder drive nonlinearity
• Setting up macro files for common tasks
