xman12 Eskönnte sein dass dieser für die Steuerung des Speedlimit ist, daher als Ersatz für Turbo ECO. Ich bin nicht sicher

xman12 Testedandworking, but you can\'t directly set an absolute max PWM level for the FAN. You can set an Min start PWM value at the beginning, to be sure that the Fan Start working. You can set an start Temperature value and an delta temperature Value. Also you can set that the fan work continuous at the min PWM level under or equal the start temperature, or can set it to Stop @ Tmin - 2C or Tmin - 5C . If the Tempsensor reach the MaxTemp and above the Fan work at 100% PWM, you can\'t set it up to go only to 80% PWM at MAXtemp. Example TempMin 35C plus DeltaTemp 15C . The Fan will spin up at 35C with the PWM Min you set at the beginning. If the Tempsensor reach Tempmin plus TempDelta, 35C plus 15C = 50C The Fan spin up to 100% You can set the delta higher to prevent that the Fan spining is to fast and loud at your max Temp. So you can indirect set the PWM Max to the wanted Level for your target Temperature. I am sorry for some textfailures Banggood change some of the text for some reason.

xman12 The original PLA has an nozzle temperatur of 200 degree, i use only 205 degree for the new PLA and it work. Since there are even more Values possible you can play arround even with higher temperatures.

xman12 You can only use it if you set SPI Mode 2 otherwise it will not work with the ESP8266.ST7789 TFT display without CS pinAdafruit ST7789 librarytft.init(240, 240, SPI_MODE2); // Init ST7789 display 240x240 pixel
