I was wondering how to switch on the build-in LED strip for the me creator 2 via G-Code.
Hoped, that M355 S1 P128 would do the trick but it doesn't.
Via LCD panel, it just works fine.

From the gcode manual:

M150 - Set RGB(W) Color
lcd Set the color of the RGB(W) LED, backlight, or LED strip. BLINKM|RGB_LED|RGBW_LED|NEOPIXEL_LED|PCA9632

If you have an RGB(W) light, either as part of a controller or installed separately, the M150 command can be used to set its color.
Usage
M150 [B<intensity>] [P<intensity>] [R<intensity>] [U<intensity>] [W<intensity>]

Argument Description
[B<intensity>] - Blue component from 0 to 255
[P<intensity>] - Brightness from 0 to 255 (NEOPIXEL_LED only)
[R<intensity>] - Red component from 0 to 255
[U<intensity>] - Green component from 0 to 255
[W<intensity>] - White component from 0 to 255 (RGBW_LED or NEOPIXEL_LED only)



M355 - Case Light Control
control Turn the case light on or off, set brightness CASE_LIGHT_PIN

Set the case light power state and/or brightness.
Usage
M355 [P<byte>] [S<bool>]

Argument Description
[P<byte>] - Set the brightness factor from 0 to 255.
[S<bool>] - Turn the case light on or off.

Notes
Requires a CASE_LIGHT_PIN to control the on/off or PWM state of the case light. The pin will need to be a 12V MOSFET pin with PWM control, or a signal pin connected to a MOSFET or relay to control the higher current required for the light.
Example

Turn the case light on at half brightness

M355 S1 P128

Sending the
M355 S1 P128
code does not lead to any change.
I haven't found how to control the lights via G-code.
Any idea, anyone?

Ok, figured it out by myself:
The lights are connected to PIN 6.
This makes it possible to switch on the lights by
M42 P6 S255

Switching off:
M42 P6 S0

And of course you could dimm the lights as well, e.g.
M42 P6 S128
