Staging Plate

Use an arbor press to insert the given quantities of M3-hex-nut into the following parts:
4x for bottom-camera-mount
3x for 3x peek-cable-clamp

Note

Be sure to change the arbor press tip for the different prints as needed.

Use bottom-camera-focus-jig to pre-focus bottom-camera
Loosen the set screw on the side of the lens, this will let the lens focal-point be adjusted
Be careful not to loosen it too much or the screw may fall out and get lost!
Remove the lens cap from bottom-camera
Rotate the camera lens back and forth to loosen any glue
Hold the PCB in one hand while twisting the lens body with your other hand
Don't be afraid to use a few pounds of force if needed
Install the bottom-camera fully into the bottom-camera-focus-jig
Put the JST-side of bottom-camera into the jig first
Connect the JST-side of the USB cable into the bottom-camera PCB
Connect the USB cable on bottom-camera-focus-jig to a computer and open its native camera viewing application
Use Photobooth if on Mac OSX or Cheese if on Linux
Confirm that the camera feed is running in 720p, sometimes it can launch in 360p or 480p
Within the camera viewing application, change the selected camera to PnP Bottom to view the camera feed of the bottom-camera

If the listed camera is something other than PnP Bottom, the device may either be incorrectly programmed or mixed up with a top-camera

Please take this as an opportunity to double-check the device name even if the computer switched to the correct camera feed automatically.

Rotate the camera lens until the live viewport shows the datum board as focused as possible
Before and after lens focusing:
Once the camera is focused, tighten the set screw to lock in the focus adjustment
Put a blue dot on the camera PCB with a sharpie to denote that the camera has passed testing
Remove the bottom-camera from the bottom-camera-focus-jig and immediately replace the lens cap
Return the bottom-camera to the red esd-safe bag

Attach bottom-camera and bottom-camera-cover to bottom-camera-mount with 4x M2.5x8-bolt
Confirm bottom-camera's JST connector is next to the zip-tie cable strain relief feature, as indicated below:
Clean bottom-light-mount print by removing any loose stringy plastic with a heat gun and/or razer blade (as needed)
Install bottom-ring-light into bottom-light-mount

Attach bottom-camera-assembly onto staging-plate with 4x M3x16-bolt
The JST cable connector found on bottom-ring-light should match the orientation shown below when installed - as close to the Opulo logo as possible and in line with staging-plate column 18
The JST cable connector found on bottom-camera should match the orientation shown below when installed - as close to the Opulo logo as possible
Plug bottom-light-harness into bottom-ring-light
Plug bottom-camera-harness into bottom-camera before securing cable to bottom-camera-mount with a zip-tie

Use four M3x16mm-bolt and 4x M3-hex-nut to secure the datum-board and datum-board-mount to staging-plate on the rear of the bottom-camera, through holes: B18, A19, A21, B22.
Use a 2.5mm hex wrench and a 5.5mm (6mm if 5.5mm is unavailable) socket wrench to tighten these bolts
The fisheye calibration pattern should be facing down, and the gold grid lines and fiducial in the center of the Opulo logo facing upwards

Clamp cables in the locations shown below with 3x peek-cable-clamp, 3x m3-hex-nut, and 3x m3x14 bolts
After securing the cables, tie them up with a rubber-band

Note

The QC inspection form will ask you if the bottom-camera was correctly focused with the orange version of the bottom-camera-focus-jig

Use this jig in the same way the blue one is operated, while leaving the camera installed on the staging-plate
- If the camera is out of focus, remove it from the assembly and repeat bottom-camera focusing.

After completing QC, perform the following steps

Add a QC PASS sticker to bottom-camera-cover
Bring the completed primary-staging-plate to the shelf for peer-review and pack-out
