This procedure is for users who require the WiFi interface to be disabled.  After doing so, the DeltaMaker will only be accessible via the Ethernet network.  If you also want to assign a static IP address to the DeltaMaker's Ethernet interface, please do so first, before disabling the WiFi interface.

Currently, the procedure to disable the WiFi interface involves logging-in to the DeltaMaker's build-in Raspberry Pi computer, and editing a file using a Linux command line text editor. Please note that some Linux experience is beneficial to ensure that this procedure is followed correctly.

To perform these steps, we recommend that you temporarily connect to the printer's Wi-Fi access point from a laptop or other computer with Wi-Fi capabilities.  The DeltaMaker's access point uses the following static IP address:

  1. Connect to the DeltaMaker Wi-Fi access point (using the password included with your printer).
  2. Browse to 
    Port 4200 will connect you the Linux command line for the Raspberry Pi
  3. Login using the username "pi", and the password provided by our tech support team.
  4. To disable the WiFi, edit the file  /boot/config.txt file, as follows, and reboot the Raspberry Pi.
  5. Using the editor of your choice (vi, nano, etc),  insert a line containing dtoverlay=pi3-disable-wifi to the bottom of the file.
  6. Save your modifications to the file (control-X in nano), and reboot the Raspberry Pi.
    sudo reboot

  7. Wait 30 seconds for DeltaMaker to reboot.   Next, ensure that an Ethernet cable is connected to the back of the DeltaMaker 3D printer; the printer will no longer be accessible via WiFi.
