LumenPnP Control Box
Introduction
The purpose of these work instructions is to cover the assembly process for the LumenPnP's Control Box. This assembly is used by the LumenPnP to contain its microcontroller and pneumatics system.
If you are preparing a diy-control-box for individual sale you must also follow the steps listed in DIY Control Box.
If you are making a DIY Control Box - follow these docs like normal until the Gundam Testing section before going to the above link.
Prepare control-box
-
Remove support material from the 3D printed
control-box

-
Glue 2x
M5-hex-nutinto thecontrol-box

Prepare pneumatics
Right-side pneumatic system
- Perform the following steps:
- Connect
vacuum-pumptosolenoid-valvewith a 70mm piece of6x4-soft-pvc-tubing-blue - Connect
solenoid-valvetoreduction-tee-4-6-4with a 60mm piece of6x4-soft-pvc-tubing-blue - Adhere a
Right Valvelabel to the end of thesolenoid-valvewire
- Connect

Left-side pneumatic system
- Perform the following steps:
- Connect
vacuum-pumptosolenoid-valvewith a 70mm piece of6x4-soft-pvc-tubing-red - Connect
solenoid-valvetoreduction-tee-4-6-4with a 60mm piece of r6x4-soft-pvc-tubing-red - Adhere a
Left Valvelabel to the end of thesolenoid-valvewire
- Connect

Install pneumatics systems into control-box
Install left-side pneumatic system
- Suspend the
vacuum-pumpin the control-box with 2xrubber-band, matching the arrangement shown below
- Click the
solenoid-valveinto the mounting receptacle as shown below
- Slide the
reduction-tee-4-6-4into the mounting bracket found next to vacuum line inlet

Install right-side pneumatic system
Repeat the above process to install the right-side pneumatic system

Bolt 2x reduction-tee-4-6-4 to control-box
- Use 2x
m3x30-socket-headand 2xm3-hex-nutto attach 2xreduction-tee-4-6-4tocontrol-box

Perform cable management
-
Tuck the Left Valve and Right Valve cables into to the cable management feature on the back wall of
control-box- Route the Left Valve wire underneath the tubing

-
Tuck the Left Pump and Right Pump cables into the back corner of the
control-box

Connect vacuum lines to motherboard-rev05
- Prepare a 145mm piece of
pu-tube-4x2.5-blue - Prepare a 165mm piece of
pu-tube-4x2.5-red -
Gather 1pcs
motherboard-rev05from inventory
-
Connect the tubes
- Connect
pu-tube-4x2.5-blueto the vacuum sensor labledRight Vac - Connect
pu-tube-4x2.5-redto the vacuum sensor labeledLeft Vac

- Connect
-
When completed the assembly should resemble the image shown below:

Screw motherboard-rev05 into control-box
-
Place motherboard-rev05 into
control-boxwhile sliding the USB and barrel jack ports into the cutouts on the left side of the print

-
Install motherboard-rev05 into
control-boxwith 4xm3x12-button-head-self-tapping-screw- Set the torque driver to ~1.5 to avoid stripping a screw hole

- Set the torque driver to ~1.5 to avoid stripping a screw hole
Connect a vacuum line to each reduction-tee-4-6-4
- Route the vacuum lines underneath the back right motherboard standoff before plugging each tube into its respective
reduction-tee-4-6-4

Perform cable management
- Connect the Left Pump, Right Pump, Left Valve, and Right Valve cables into the corresponding ports on
motherboard-rev05
- Run the cables back along the pathway between the two rows of connectors
- Add a
zip-tiearound all four cables to keep them well managed
You may now proceed to Gundam Testing!
Gundam Testing
- Install
control-box-asminto Gundam

- Remove
control-box-lidand set it aside
- Connect the vacuum tubes, being sure to match the colors up correctly

- Begin to connect the Gundam jig's cables into
motherboard-rev05

- Proceed to connect USB-B cable to the motherboard.
- Hold the
BOOTbutton on the motherboard, and plug in the 24v DC barrel jack while holding it. After two seconds, you can stop pressingBOOT. - In a new terminal window, type
flashmarlinto install the firmware onto the motherboard. - Once complete, press the
RESETbutton on the motherboard. - Open the Gundam test software.
-
If it's not already open, in a new terminal window, just type
gundam. -
Select the “REV05-Mobo.json” test from the dropdown menu, then hit “Run Test”.
-
Perform each of the tests in Gundam, and follow the prompts.
-
If some of the tests fail, continue through the rest of the test until every test has been run.
-
The last test is assigning the control box a serial number. Only perform this test if all others have passed. We only want to assign a serial number to a working control box.
-
This text just prompts you for a serial number. Grab a new serial number sticker from the sheet and a new 4"x6" label from the pile, ensuring the serial numbers match, and input the serial number into the prompt for the test.
-
Unplug the USB and Power cables from the control box.
-
Unplug all of the cables and pneumatics from the control box.
-
Put the serial number sticker in the recess in the back of the control box

-
Fit a lid on the control box, and make sure the 4"x6" label is sandwiched between the box and the lid.

-
Check that both buttons click well.
The control box has passed Gundam QC testing!
