Remove the BeagleBone

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

  1. Completely unload print material. For more information, see Unload Plastic and Unload Fiber, if applicable.
  2. Power off and unplug the printer.
  3. Remove and set aside the Wi-Fi antenna / Ethernet cable.
  4. Remove and set aside the print bed and any fiber spools.
  5. Disconnect the feed tube from the plastic extruder. Remove it from the printer and set it aside.
  6. Tape the lid and visor of the printer closed to prevent them from accidentally opening.
  7. Carefully turn the printer upside down so that the bottom is facing up and the rear of the printer is facing toward you.
  8. Use the Phillips screwdriver to remove the ten screws that hold the bottom panel in place.
  9. Remove and set aside the bottom panel.
  10. The touchscreen and BeagleBone are located at the center of the front face of the printer, furthest away from you. The motherboard is located near the rear face of the printer, closest to you.
    Note: The metal cover over the BeagleBone may be black, silver, or orange; the color has no bearing on these instructions.


  11. Disconnect the four black cables on the left and right sides of the BeagleBone. Do not attempt to disconnect the grey cable from the BeagleBone.
  12. Use the 2mm hex key to remove the two black screws that secure the BeagleBone cover to the touchscreen assembly.
  13. Disconnect the 3-wire connector at the end of the grey cable from the motherboard.

  14. Using wire cutters or a similar tool, cut the black zip ties that hold the wires connecting the motherboard to the BeagleBone.
    Note: Be careful not to cut the wires.

  15. Pull the BeagleBone and aluminum cover straight off the touchscreen assembly. Note the two white spacers that sit under the tabs on either side of the aluminum cover.

  16. Using the 2mm hex key, remove the four screws attaching the BeagleBone to the aluminum cover, then separate the BeagleBone from the cover.
