Dune Weaver Pro Assembly Instructions

Assembly Steps

1. Assemble the IKEA leg upside down

2. Add the base and secure the base aligner underneath with 4 M4x15mm self-tapping wood screws

3. Connect the motor cable, add the motors and secure the motors to the holder with 4 M3x10mm machine screw for each motor. Secure the motor with the aligner to the base with 2 M4x15mm self-tapping wood screws for each motor.

4. Add the bearing to the outer bearing holder. Secure with M4 set screws or scale the model for a tight press fit. You can also use a dab of glue to hold the bearing in place.

5. Add the inner bearing to the angular gear and glue it in place. Wait for the glue to completely dry.

6. Press fit the angular gear to the bearing. Add set screws or glue to secure it in place. Make sure that the inner bearing moves when the angular gear moves.

7. Add the assembly to the base and secure with 4 M4x15mm self tapping screws.

8. Add the radial arm and the inner spur gear

9. Secure the Raspberry Pi 2W (with usb cabled attached). Then secure the dlc32 board on top of the usb cable. Test electronics before proceeding with wiring.

10. After completing wiring, install the electronics cover

11. Trace and cut out the EVA to the shape of the wooden base. Add minimal glue if EVA foam curls.

12. Add the led wires

13. Assemble the enclosure around the wooden sand bed

14. Optional: Caulk the bottom of the sand bed to prevent sand from escaping

15. Add approximately 1.4kg of sand and the magnetic ball. Sand should cover about 25% of the magnetic ball height. Install the LEDs and solder connections.

16. Add the LED cover to the glass and put the glass ring on

17. Put the sand bed on the four legs. Add the glass ring with the glass on top

Wiring

Pi Zero 2W and DLC32 Connection

• Add the Pi Zero 2W and wire to the DLC32. If using WLED (deprecated; use DW LEDs instead), attach ESP32 as well.

• USB Connection Options:

  • Use USB-a to micro USB adapter to connect dlc32 to Pi (skip next step)
  • Alternatively, set up UART over pins following additional instructions

• Set the 3 switches under the motor drivers to off for both axes

• Adjust Vref values using the provided instructions.

Power Supply

• Single 12V 5A supply powers everything
• Current requirements depend on LED choice
• Example: 12V WS2815 60 LEDs/m
• Higher LED density may require increased current capacity

Connection Notes

• Use Dupont wires for Pi Zero 2W and ESP32 board (prone to issues; consider soldering after testing)
• Confirm all electronics function before final assembly

Power Cable Installation

• Connect power cable to female 12V plug
• Run power wires through the steel tube

LED Wiring

• Create connector plug for LED removal when detaching table top

• Green cable = data cable (connects to pin 16 on ESP32)
