Staging Plate

Install hardware into 3D printed components

  • 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.

Removing punch-out from PCB-0003

  • Remove the punch-out from center of PCB-0003 with flush cutters

  • Clean up hole with a deburring tool after punch-out has been removed

  • Clean both sides of PCB-0003 with an IPA-soaked shop rag

Focus the bottom-camera

  • Thread the bottom-camera-cable through bottom-camera-cover and connect it

  • Remove the lens cap from bottom-camera

  • Use bottom-camera-focus-jig to pre-focus bottom-camera

  • Turn on the light for the jig and attach bottom-camera

  • 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

Creating bottom-camera-assembly

  • Attach bottom-camera and bottom-camera-cover to bottom-camera-mount with 4x M2.5x8-bolt

  • Confirm bottom-camera's JST connector is in the correct orientation 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

Final Assembly

Installing bottom-camera-assembly

It is recommended to wear gloves when handling the staging-plate.

  • 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

Install datum-board and datum-board-mount

  • 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

Install secondary fiducial

  • Use two M3x10-hex-head to attach secondary-fiducial-bracket to staging-plate. Make sure the closed portion of the. bracket is facing the ring-light.

  • Fasten secondary-fiducial-bracket to staging-plate with two m3-hex-nut.

Performing cable management

  • Clamp cables in the locations shown below with 3x peek-cable-clamp, 3x m3-hex-nut, and 3x m3x14 bolts
