Touchscreen Removal

Note: Take care not to discard any hardware you remove during this procedure, as you may need it during the reinstallation.

  1. Unload all print material from the printer and remove the print bed. For more information, see Unload Plastic and Unload Fiber, if applicable.
  2. Disconnect the feed tube from the plastic extruder. Remove it from the printer and set it aside.
  3. Remove and set aside the print bed and any fiber spools.
  4. Power off your printer and unplug the power supply from the back panel.
  5. Remove and set aside the Wi-Fi antenna / Ethernet cable.
  6. Tape the lid and visor of the printer closed to prevent them from accidentally opening.
  7. Perform a two-person lift to remove the printer from the lower cabinet. Place the printer upside down on a flat, stable surface.
  8. Using a 2mm hex key, remove the 12 screws that attach the bottom plate to the printer and set them aside.

    Note: There are four additional spacers between the touchscreen and the printer casing. Ensure that you set these aside to be reinstalled later.
  15. Carefully pull the BeagleBone and the old touchscreen apart. If necessary, gently rock the BeagleBone from left to right to loosen it.

Touchscreen Replacement

  1. Connect the replacement touchscreen to the BeagleBone, using the markings on the touchscreen board to properly align the connectors. Apply firm, even pressure when inserting the pins.
  2. Align four white spacers with the holes around the touchscreen opening in the printer casing.
  3. Keeping the grey cable out of the way, carefully seat the replacement touchscreen into its opening, aligning the holes on the board with the spacers as well as the holes in the printer casing.
    Note: Ensure that the USB port on the BeagleBone faces toward the USB hub.
  4. Place two spacers directly on the exposed corners of the board and insert the other two between the touchscreen board and the tabs of the BeagleBone cover.  
  5. Use the 2mm hex key to install two screws into the holes in the corners of the touchscreen that are not covered by the tabs of the metal BeagleBone cover. Ensure that the screws pass through the spacers.
