Duet 2 Wifi

Connect remotely and work freely using Duet 2 Wifi with an advanced 32-bit processor.


This is the latest PCB revision of the Duet 2 WiFi, v1.04.

Duet 2 WiFi is an advanced 32-bit electronic controller for 3D printers and other CNC machines. It has the same features as the Duet 2 Ethernet other than providing WiFi connectivity rather than ethernet.


  • Powerful 32 Bit Processor
  • Dedicated Wifi module with either: a compact built-in antenna and an external antenna for extending Wifi range or allowing the Duet 2 Wifi to be mounted in a shielding enclosure with the antenna outside
  • Super quiet TMC2660 stepper drivers, up to 256
  • High-speed USD card and support for a second external SD card if
  • Dual extruders on the mainboard, up to 5 more extruders on the expansion board
  • High Power rating: Each stepper driver is capable of an 8A motor current, currently limited in software to 2.4A. The bed heater channel is specifically designed for high current (18A)
  • Connect via PC, tablet, or smartphone on the same network to the onboard web interface
  • Set up your printer and update the firmware through the web interface
  • All common 3D printer geometries are supported
  • Expandable up to 7 extruders with Firmware support for mixing nozzles and remapping axes to use high power external
  • Support for the PanelDue: a full-color graphic touch screen
  • Support for DC42’s IR Z probe and the Duet3D Smart Effector for delta
  • Provided with Molex compatible plugs and crimps as well as ferrules for power and heater


The Duet 2 Wifi can have Thermistors connected directly. Alternatively, Duet has two different temperature sensing daughterboards available:

Duet also provides genuine E3D PT100 and thermocouple sensors compatible with their range of hotends:
