To set up a network connection, we must use a terminal emulation program to talk to the Duet via the USB cable. We recommend using YAT in Windows. This is because 3D printer host programs (such as Pronterface) send all characters in uppercase, and your WiFi settings (SSID and password ) are case sensitive.

Windows users: Download YAT here. Install YAT using default options.

Setup YAT to use <LF> as the end of line character. Go to "Terminal" Menu -> "Settings" -> "Text Settings" -> "EOL sequence:" set to <LF>

Mac OSX Users: Open Applications > Utilities > Terminal .

Run ls /dev/tty.* Copy the result that has USB in the name. For example; /dev/tty.usbmodem1411

Run screen /dev/tty.usbmodem1411 115200. Replace "usbmodem1411" with the result you received. You should see a blank screen. Hit enter and you should see OK returned. You are connected successfully.

If you get an error, Sorry, could not find a PTY. unplug the USB, plug it back in and try again.

Some users have reported issues with YAT under Windows 8 not connecting properly. If YAT does not work, try Pronterface to confirm the computer can talk to the Duet
