Duet WiFi – Activate and connect the WiFi… when it doesn’t work!

Guess we’ve all tried it.. just can’t get the WiFi to connect to our home network. Especially after a firmware upgrade.

For some reason the non-macro manual method doesn’t always work, and I’ve learned that the most simple solution then, is to create a macro file with the needed info and execute the macro.

This post is a boiled down version of my Duet WiFi/Eth – Recover from Erase + basic setup post.

Macrofile for networksetup

  • We need to create a small macrofile to make it connect to our WiFi.
    I tried doing this manually without the Macro, but I simply just could not get it to connect..
  • So, go to your Macros folder on your SD card and create a new file named SetNetwork containing the following commands (without spaces before or after the commands on each line):
    M552 S0
    G4 P1000
    M587 S"your-network-ssid" P"your-network-password"


    Source info
  • Now eject the card from your computer and insert it into your Duet WiFi and connect it to your computer using the USB cable

Activate WiFi

  • Connect to your Duet WiFi using Pronterface and type M552 S0 to start the WiFi module
    M552 S0
    SENDING:M552 S0
    WiFi module started
  • Type in M98 P/macros/SetNetwork to execute the macro we created
    >>> M98 P/macros/SetNetwork
    SENDING:M98 P/MACROS/SETNETWORK
    WiFi module started
  • Send M587 and check that your network is listed
  • Send M552 S1.
    After a few seconds you should see a message that it has connected to your access point and display the IP it has recieved.
  • Connect via the web interface
  • Enable the M552 S1 command in config.g – if it’s not in there, then just make a new line and type it in.
  • For security reasons you might want to delete the SetNetwork macro file

SD Card Folder Structure

It’s usefull to know how the structure is supposed to be on the SD-card and also to know the function of each of the files and more info.

All this is shown on the SD Card folder structure wiki page
