DUET 2 Wifi boards v1.05.

The Duet 2 Wifi is an advanced 32 bit electronics for the control of 3D printers and other CNC machines. It has the same features as the Duet Ethernet other than providing a WiFi connectivity rather than ethernet, full feature description is available on the wiki, in summary:

  • Dedicated Wifi module with EITHER :
    • a compact built-in antenna
    • a external antenna for extending Wifi range or allowing the Duet 2 Wifi to be mounted in a shielding enclosure with the antenna outside.
  • Powerful 32 Bit Processor
  • Dedicated Wifi module
  • Super quiet TMC2660 stepper drivers, up to 256 microstepping.
  • High speed SD card and support for a second SD external card if required.
  • Dual extruders on the main board, up to 5 more extruders on the expansion board.
  • High Power rating: Each stepper driver is capable of 2.8A 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 on board web interface.
  • Setup 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 drivers.

Wish I had upgraded to a duet sooner

I blew one of the stepper drivers on my printer's original RAMBo board, and I decided to take the opportunity to upgrade. I sure wish I had done it sooner, because this board is fantastic! Much quieter motors, smoother motion without any stalls, the surface finish of the prints is better, and small holes are much closer to proper size! It takes some patience and work to retrofit into a printer, but absolutely worth it. Definitely recommend.

Duet 2 wifi

Why don't they give you a basic manual with standard instructions rather than guessing from reprap and still find nothing that will work. I'm dreaming that YouTube videos will help and get this WiFi running right. Chris

Yea, this one works. I bought again because i got hooked on the web control and touchscreen display sold seperately.

Awesome hardware and support

I've owned my Duet2 Wifi and PanelDue7 hardware for a few months. In that time, I've received incredible support by Spool3D and great support in the official Duet3D forums. I'll be purchasing another Duet3D board as well as many other components from Spool3D soon.

Best 3D Printer controller you cna buy

I could not be happier with the Duet2 WiFi controller board and PanelDue 7 combo. My printer so silent the PSU fan is the only thing I hear running even when all my axis's are going. The granular precision on the printers movement is also very apparent . This board is amazing.

Amazing Upgrade

I have an Anet A6 that I have rebuilt and swapped out almost every part on. I bought this board so that I could swap out the mainboard and try the new stepper drivers and I have been blown away by the difference this has made. The BLTouch is working better than ever, and I am now able to consistently get good bed compensation, I was able to split my two Z-motors to independent drivers, and now my x-axis is actually level(yay for autolevelling), whereas before even with a counterweight on the far side it would shift out of balance after almost every print. But the thing that has blown me away the most is how much nicer the extrusion is. My surface finish is far smoother than I was ever able to achieve with the stock anet board running the most recent version of Marlin. I had tried swapping out hotends to the E3d Volcano and using the Titan extruder in both direct drive and Bowden mountings, and there was always a lot of stringing. Now I can finally get clean finishes, with virtually no stringing. Oh and I am actually able to print way faster too because now I can control the current being sent to the motors, which alloed me to eliminate a y-axis slipping problem that had been plaguing me from day 1. Oh yeah, and there are now enough inputs that I can run a filament sensor and a BLTouch. The web interface is pretty nice too, I miss a few things from my octopi, but so far the tradeoffs have been worth it by a mile. I really like this board, and I will definitely be using it for the custom coreXY build I've been planning.
