Human: https://youtu.be/4R88qWi_j-I Perfect accessories for 3D printer with Marlin fw. Need to enable this feature in Configuration.h: #define RGB_LED And change pins for rgb led: #if ENABLED(RGB_LED) || ENABLED(RGBW_LED) #define RGB_LED_R_PIN 6 #define RGB_LED_G_PIN 4 #define RGB_LED_B_PIN 5 #define RGB_LED_W_PIN -1 #endif test Next you can (but its not necessary) change in Marlin_main.cpp: Red color in critical error or kill: void kill(const char* lcd_msg) { #if ENABLED(PRINTER_EVENT_LEDS) leds.set_color(LEDColorRed()); #endif SERIAL_ERROR_START(); ...... Next you can change main loop() like this: ////////////////////////////////////////////////////////////////// #if ENABLED(PRINTER_EVENT_LEDS) unsigned long previousMillis = 0; const long interval = 1000; byte stavled=0; #endif ////////////////////////////////////////////////////////////////// void loop() { ////////////////////////////////////////////////////////////////// #if ENABLED(PRINTER_EVENT_LEDS) leds.set_color(LEDColorGreen()); const byte beda=thermalManager.degTargetBed(); const byte heda=thermalManager.degTargetHotend(target_extruder); if(beda<1 || heda<1){ unsigned long currentMillis = millis(); if (currentMillis - previousMillis >= interval) { previousMillis = currentMillis; if (stavled==0) { if(beda>1) leds.set_color(LEDColorYellow()); if(heda>1) leds.set_color(LEDColorYellow()); if(beda<1 && heda<1)leds.set_color(LEDColorGreen()); stavled=1; } else { leds.set_off(); stavled=0; } } } #endif //////////////////////////////////////////////////////////////////
