Can you control the Hot End RGB LED via GCODE? #4

I know it can be turned on via the screen, but can you do it via gcode?

Yes. See https://marlinfw.org/docs/gcode/M150.html.

Hello, I tried the M150 command light all led's in white (M150 B100 R100 U100). But only the left led is white, the right one is green. any idea how to properly light them up? looks like a little jitter I know from neopixels at the end of the signal line which are not properly addressed. Thank you!

In my Marlin firmware I changed the following code;

define NEOPIXEL_PIXELS 2

//#define NEOPIXEL_IS_SEQUENTIAL (disable this) You should then be able to control both LED's using the M150 command. Also the M150 command has an index switch (I) you can use also. https://marlinfw.org/docs/gcode/M150.html

did you try M150 RUB that should be all white. unless you have a white led configured, then it would be M150 W

BTW, 255 should be 100%
