USB - G-code

Connecting to WiFi

  1. Connect USB to computer
  2. Use command “M550 SSID” - Replace “SSID” with the name of your WiFi network
  3. Use command “M551 PASSWORD” - Replace “PASSWORD” with the password for your WiFi network
    Need help on how to send these commands? See Sending G-code
  4. You should see IP address displayed in title bar where no connection was once displayed
M550 SSID         ;SSID = Name of WiFi network (case sensitive)
M551 PASSWORD     ;PASSWORD = Password for WiFi network (case sensitive)


  • WiFi and USB cannot access simultaneously.
  • Disconnect USB cable from the printer if you want to use the WiFi function.
  • WiFi works with 2.4 GHz b/g/n networks only.
  • These next two notes apply to when connecting using the Android & iOS apps.
    1. If you have a 2.4 GHz and 5 GHz network using the same SSID(wireless network name) you may have trouble connecting the printer.
    2. For initial WiFi setup try moving the printer closer to the WiFi router.
