To set up a WiFi network connection, we must use a terminal emulation program. 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
