### Basic Information:

Voron 2.4  
Octopu v1.1  
 `klippy.log

My issue:  
Hi, I’m trying to get the provided 3 LED’s mounted in the Stealth burner to work on my Voron 2.4. I’m illiterate when it comes to macro’s and what not. I was wandering if anyone has a working config that I could just copy into mine with a little extra help involving which directories / pins I need. ( my board says the LED connection is J37 ) I have tried to follow the provided installation instructions ) just don’t have enough knowledge to be successful. Thanks so much in advance.

It’s very easy to do.

On the Octopus V1.1, the connector is J37 but the critical information is that it’s pin `PB0`.

So, to define it, in printer.cfg you use the `[neopixel ...]` statement like:

```auto
[neopixel panel_ring]
pin: PB0
chain_count: 3
#initial_RED: 1.0
#initial_GREEN: 1.0
#initial_BLUE: 1.0
#initial_WHITE: 1.0
color_order: GRBW

```

You can set different initial colors or their brightness. In Mainsail, a control comes up for it automatically on the Dashboard, allowing you to play with the different colors as well.

Along with this, you can use a canned set of macros like:

> **[GitHub - digitalninja-ro/klipper-neopixel: Klipper NeoPixel Templates](https://github.com/digitalninja-ro/klipper-neopixel)**
>
> Klipper NeoPixel Templates. Contribute to digitalninja-ro/klipper-neopixel development by creating an account on GitHub.

Which can be invoked from the command line or from inside your printer.cfg to carry out different tasks.

Have fun!

Thank you Sir. I’ll give it a try!
