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
orfeeder-frame-12mm
LOCTITE 435
8mm-fiducial-board

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.

- 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 installlight-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 Opulo logo on
-
The installed
light-diffuser-pcb
should be flush to the top-face offeeder-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
or12mm-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
