🔧 Materials Needed

• Neopixel LEDs – We used Black PCB, 1m 74 IP30, but feel free to choose your desired density (e.g., 144 LEDs/m).
• Wires – Three wires for power, ground, and signal.
• Soldering Kit – Ensure to solder correctly, following the directional arrow on the PCB!
• Connector JST – For connecting to the Manta board.
• BTT Manta M5P – Your baseboard where the LEDs will be connected.

🛠️ Step 1: Physical Installation of LEDs

1. Unboxing and Preparing LEDs: Start by preparing your Neopixel LEDs. You can use 74 LEDs/m or opt for 144 LEDs/m for a more consistent lighting effect.
2. Wiring and Soldering: Solder the three wires to the LED strip, ensuring to follow the directional arrow on the PCB that indicates signal direction.
   • Common mistake: Don’t solder on the wrong side (the direction of the arrow is crucial).
3. Connecting to the Manta Board:
   • Use a JST connector to hook up the LEDs directly to the RGB1 port of the Manta board:

🖥️ Step 2: Klipper Configuration for LEDs

1. Download the Configuration File: Download the leds.cfg from this GitHub link and place it in the ~/printer_data/config/ directory.

2. Edit printer.cfg:

   • In your printer.cfg, include the line [include leds.cfg] to load the LED configuration file. Uncomment this line by removing the #.

3. Configure the LED settings: In the leds.cfg file, adjust the following parameters:

   • Pin: Specify the pin depending on where the LEDs are connected. Use PC11 for RGB1 and PC14 for RGB2.
   • Chain Count: Specify the number of LEDs in your chain. For example, chain_count: 22.

   pin: PC11  # Pin connected to the Neopixel LEDs.
   chain_count: 22  # Number of Neopixels in the chain.
   

🚀 Step 3: Installing Klipper-LED_Effect Plugin

1. SSH into Your CB1: Open a terminal and SSH into your CB1 board.

2. Run the following commands to clone and install the Klipper-LED_Effect plugin:

   cd ~
   git clone https://github.com/julianschill/klipper-led_effect.git
   cd klipper-led_effect
   ./install-led_effect.sh
   

3. Configure LED Effects: Follow the instructions in the Klipper-LED_Effect repository to set up and customize various LED effects.

✅ Step 4: Testing and Verifying LED Installation

1. Restart Klipper: Once everything is installed, restart Klipper for the changes to take effect.
2. Test LED Operation: Use commands in the Klipper console to check if the LEDs are functioning correctly. Adjust the effects or configurations as needed.
3. Troubleshooting: If the LEDs don’t light up or behave unexpectedly, double-check the wiring and ensure that the leds.cfg file is correctly configured.

Happy printing with your glowing setup! 🌟

Optional: Go to BTT TFT35 SPI installation
