Adding RGB control

[Power3DPrinting]

I have some "neopixel" 24V RGB 5050 light strips one of 12 LED's and another of 6 LED's wired to 24V power and individually controlled by servo pins P1.24 and P1.25. The LED's turn on with the printer because of the 24V power but I am not getting any start up light control or status indication colors when printing. The LED's only change color when powering off the printer where they fade in different colors as they lose power. Any ideas how to get the LED's to change colors when printing?

/**

• RGB LED / LED Strip Control
• Enable support for an RGB LED connected to 5V digital pins, or
• an RGB Strip connected to MOSFETs controlled by digital pins.
• Adds the M150 command to set the LED (or LED strip) color.
• If pins are PWM capable (e.g., 4, 5, 6, 11) then a range of
• luminance values can be set from 0 to 255.
• For Neopixel LED an overall brightness parameter is also available.
• CAUTION
• LED Strips require a MOSFET Chip between PWM lines and LEDs,
• as the Arduino cannot handle the current the LEDs will require.
• Failure to follow this precaution can destroy your Arduino!
• NOTE: A separate 5V power supply is required! The Neopixel LED needs
• more current than the Arduino 5V linear regulator can produce.
• CAUTION
• LED Type. Enable only one of the following two options.

Hi! You can refer to marlin configuration.h file

/**

Am I not in the configuration.h file...? I have the same thing as I showed. Not sure why it isn't working.

@Power3DPrinting I has test RGB function and i use the latest marlin bugfix 2.0.x, it is work, but i use MKS SGEN_L V2 motherboard

• LED will change to red when current temp = target temp
• LED will change to white when printing
• LED will change to green when print finished

https://github.com/MarlinFirmware/Marlin/pull/19762 But MKS SGEN_L V1 have no pins with P1_19/P1_20/P1_21

@Power3DPrinting I will close this question temporarily.
