Hi, I added mod for LED light.
How to turn LED on GTM 32 PRO (M301)
Which command need to be issued before print to turn on LED pin (2 pin LED connector in the corner of the GTM 32 Pro)?
Also which command control PWM on 2 fan connector on board ?
If those are not PWM then which command to use on extruder 0-2 (1-3) for FAN PWM?

Thank you

Hi,could you take some pictures about the LED connection with the board?

Here it is...in corner right next to the display connector. 2pin connector with LED marking on the board. I assume there is command that needs to be triggered to turn on pin on the CPU.
It would be nice to have this option in printer menu like on some other printers. Something like MENU-CONTROL-LED- on/off

Hi William,

do you have solution? Should be simple as issuing command to power pin that lights the led.

Hi,I'm afraid that the led cannot be controlled in LCD panel.
