thingiverse

<h2>Bullseye Duct for RGB LED Ring with Ender 3 PRO</h2> For the ring, you'll need: * Inner diameter: 7.2 cm * External diameter: 8.5 cm * Pixels count: 24 To mount it, use stock 2mm screws. Behind the mount is a hole for removing wires. Revision 13.05.2020 Now I'm using an Orange Pi Zero and scripting with sh to control the LEDs: 1. Add user "octo" to group gpio: `sudo adduser octo gpio` 2. Use "gpio readall" to see pin statuses 3. Install libraries from: * https://github.com/doceme/py-spidev.git * https://github.com/joosteto/ws2812-spi 4. Configure permissions: `chmod 666 /dev/spidev1.0` and `chown octo:octo ws2812.py` 5. Make the script executable: `chmod +x wr ws2812.py` Use these scripts to turn the LEDs on or off: * `--led on`: `python ~octo/.octoprint/scripts/ws2812.py -n 24 -c [[10,10,10]]` * `--led off`: `python ~octo/.octoprint/scripts/ws2812.py -n 24 -c [[0,0,0]]` Add these scripts to the action command in Octoprint: <a href="https://s.click.aliexpress.com/e/cH4ttoOe">RGB LED Ring 24 pixels WS2812 5050</a> Get the Petsfang Bullseye models from: <a href="https://www.thingiverse.com/thing:2759439"></a> Learn how to control WS2812 SPI on RASPI from: <a href="https://github.com/joosteto/ws2812-spi">SPI ws2812 control RASPI</a> Revision 12.12.2019 - Increased fan location size
