General Discussion

Was trying to connect stealthburner toolhead on my ender 3. In my control board wasnt pin for led control, so decided to try gpio pins.

Connected to GPIO12 (PWM) on raspberry pi zero 2 W.

pin: host:pwmchip0/pwm0

after trying to save and restart it is not showing any error only this :

Hello @krossek !

Have you done what is mentioned here: RPi microcontroller - Klipper documentation ?
