8mm/12mm Feeder Frame Assembly

This section will guide the reader through the process of installing various hardware components into feeder-frame-8mm or feeder-frame-12mm in preparation for its use in final assembly.

Materials Needed

  • feeder-frame-8mm or feeder-frame-12mm
  • LOCTITE 435
  • 8mm-fiducial-board or 12mm-fiducial-board
  • light-diffuser-pcb
  • arbor-press-jig
  • heat gun potentially
  • needle nose pliers

Prepare feeder-frame-8mm/feeder-frame-12mm

  • Inspect the print for defects.

    • Use a heat gun to remove any stringing.
    • Check the first layer to ensure it is free of defects and printed on the textured print bed as shown.

Hold it Partner

  • Make sure to double check you are working with the frame you intended to work with. You can always check the numbers on the frame to indicate if you are working with 8mm or 12mm frames.

  • Inspect for loose plastic in the overhanging region of the pick-window on the frame.

    • Remove any loose plastic with a knife as needed.

    Rework Needed

    OK

  • Remove the support from frame with fingers or needle nose pilars.

Install Light Diffuser

  • Use an arbor-press-jig to install light-diffuser-pcb (PCB-0013-01) into intended feeder frame.

    • The Opulo logo on light-diffuser-pcb should be in the correct orientation when the feeder is held in front of you.

  • The installed light-diffuser-pcb should be flush to the top-face of feeder-frame-8mm when installed correctly

Buttons

  • Firmly press the up and down buttons so that they can move freely

Hold it Partner

  • These buttons are print-in-place flexures, which means they need to be broken away from the layer of plastic between the buttons and frame.
  • Exercise care here, as pressing these buttons too far inward or outward can break them
  • The motherboard that is installed later will prevent the damage from the buttons moving too far inwards.

Install 8mm Fiducial Board/ 12mm Fiducial Board

Hold it Partner

It is important to be aware that the fiducial for the 8mm & 12mm frames are slightly different.

  • Be aware what frames you are working with
  • Be aware what fiducials you are gluing

  • Add a small amount of LOCTITE 435 in the front pocket of the feeder frame you are working with

  • Manually install 8mm-fiducial-board or 12mm-fiducial-board into the front pocket of feeder frame

    • The fiducial markers should remain visible when installed

  • Orient frame upright for 30 minutes to allow LOCTITE 435 time to cure
