RepRap Ltd DuetWifi board testing

  • The DuetWiFi was easy to wire up to one of our existing RepRap Ormerods. The mount holes are in the same place as the Duet 0.6 we were using previously in this printer. We had to create couple of additional wires to connect up the power input, the heated bed and the hot end heater.

    The online wiring diagrams were very clear and easy to follow.

    I tried to connect wirelessly to the Duet deciding that instructions were for wimps and failed. Then Sally told me to read the instructions and they succeeded first time. The wifi setup is slightly more complicated than a wired network because, for security, it is essential for the Duet to connect to the correct hub, not just any wifi in range. We did have to download the latest version of Pronterface as the older version we were running did not have the correct Baud rate to allow us to use the USB interface to set up the wifi. We hadn't upgraded our Pronterface for a long time as we never use it; we always use Chris Hammacher's elegant web interface to control all our machines with a Duet in them.

    On the new Duet the web interface works very nicely, and we found it most useful because it allows you to configure every aspect of the machine with a web browser including all its set up parameters.

    We ran our first test print - it was immediately apparent that the motor controllers are beautifully smooth and quiet and the print came out very nicely (it's a cleaning hook for the grass blower tube on a lawnmower…).

    All in all very nice, very impressive board.

    Best wishes

    Thanks for the review Adrian
    Can you send through your configuration and I will ask Christian to update the RepRapFirmware configuration tool for the Ormerod.

  • Hi Tony. No prob. It is (with a certain amount of TAB/SPACE confusion…):
    Best wishes Adrian
