LED light settings Klipper

[hidara2000]

I have tried multiple times to get the nozzle lights to light up. Logo is fine. below is my config. Any suggestions?

[neopixel sb_leds]
pin: EBBCan:PD3

chain_count: 9
#   The number of Neopixel chips that are "daisy chained" to the
#   provided pin. The default is 1 (which indicates only a single
#   Neopixel is connected to the pin).
color_order: GRBW
#   Set the pixel order required by the LED hardware. Options are GRB,
#   RGB, GRBW, or RGBW. The default is GRB.
initial_RED: 0.0
initial_GREEN: 1.0
initial_BLUE: 0.0
initial_WHITE: 0.0
#   Sets the initial LED color of the Neopixel. Each value should be
#   between 0.0 and 1.0. The WHITE option is only available on RGBW
#   LEDs. The default for each color is 0.#
#
# Most configuration for the macros can be done by modifying the variables in the _sb_vars macro

I am having the same issue. Have you solved it? I am going to try a 100 ohm resistor on the data wire near the MCU. No idea if it will work but worth a try.

[hidara2000]

Any luck?

[Chemcam]

Unfortunately no. I was advised from others that it is common. Bin the lights and buy another led kit with soldered joints.

[TheUltimateC0der]

I had the same issue for a few days now, and couldnt figure it out. Came to this issue to see that chain_count: 9 setting.

That made me courius to test. I also thought that since there are only 3 PCBs that the LEDs on the logo PCB count as one.

Turns out that they dont count as one and each individual LED is adressable. So 8 LEDs for the logo PCB and 2 LEDs for the nozzle made a total of 10.

chain_count: 10 did the trick. At least for me!

[Interfredzo]

from https://github.com/tanaes/whopping_Voron_mods/tree/main/LEDs/Rainbow_Barf_Logo_LED this does the trick. Last two LEDs are GRBW LEDs. Therefore you need to configure color order for those seperatly.
