 Product Description

Duet 2 Wifi - Motion Controller

The DuetWifi is the next generation of 3D printing electronics, designed and manufactured as a collaboration between Think3Dprint3D and Esher3D. This builds on the success of the previous generations of the Duet 3D printer controller and the most advanced 3D printing firmware: RepRapFirmware. By ordering a Duet WiFi you will be supporting both the DuetWifi hardware development and the continued development of RepRapFirmware. All customers are encouraged to give feedback on the forum (see further developments below).

  • Powerful 32 Bit Processor
    • Atmel SAM4E8E: 120MHz ARM Cortex-M4 microcontroller with floating point unit, 512Kb flash memory, 128Kb RAM and many peripherals.
  • Super quiet TMC2660 stepper drivers
    • SPI controlled stepper drivers capable of up to 256 microstepping. Current and microsteps can both be changed on the fly for optimum speed and power efficiency.
  • Dual extruders
    • 3 heater/thermistor channels for a heated bed and 2 extruders. 3 PWM controllable and 2 always-on fans. These can be run from either the input voltage, from 5V, or from external power for added flexibility.
  • High Power rating
    • Each stepper driver is capable of 2A motor current, with further increases possible after thermal testing. The bed heater channel is specifically designed for high currents.
  • Dedicated Wifi module
    • Running on a separate processor, this leaves the main processor free to do precise stepper pulse timing and implement other advanced features.
  • Flexible
    • Connect via PC, tablet or smartphone on the same network: there is no need for an app install or internet connectivity. Also connect via USB or serial if desired.
  • Cable-free control
    • Use your printer in any room covered by your WiFi network. No need to be tethered by USB or Ethernet cabling any more.
  • Security
    • WPA-2 encryption for network security, with further security changes coming soon. The DuetWifi does not need to be connected to the internet - keep it on a local network for added security.

V1.04. The full list of changes is as follows:-


  • EMI reduction measures, indicated by V1.04 and CE marks on the silkscreen.
  • Provision of a blade fuse for the Motors and heaters - Supplied with a 7.5A fuse
  • Provision of a blade fuse for the Heatbed - Supplied with a 15A fuse.
  • Replaced erase switch with an erase jumper


The new V1.04 Duet 2s are flashed with the recently-released Duet2CombinedFirmware Release 2.0, the first version to use a real time operating system. It includes a number of new features and bug fixes - for details see the release notes.




It is important to note that apart from the extra firmware features and reduced EMI, the new Duet 2 V1.04 will behave identically to the current V1.03 in normal service, and there are no changes to external dimensions or connector positions.

 NOTE: Duets include connector packs and a USB cable standard.

  1. Amazing upgrade from Rambo board

    Posted by Unknown on 26th Jul 2017

    Upgraded my Rostock V2 with this controller, and in combination with the JohnSL FSR kit, the results are nothing short of astonishing. I have my axis motors on 32 micro stepping and my extruder on 128 micro stepping, and the improvement in print quality still amazes me. The biggest quality problems I have now are from the faceted faces in the STL files. Definitely get a Panel DUE with this controller though, it adds an amazing amount of functionality, especially if your WiFi is not perfect. Don't forget to set a static IP for the printer in your network!
