  392.    * Constant compensation (use only with fanspeeds of 0% and 100%)
  393.    * ---------------------------------------------------------------------
  394.    * A good starting point for the Kf-value comes from the calculation:
  395.    *   kf = (power_fan * eff_fan) / power_heater * 255
  396.    * where eff_fan is between 0.0 and 1.0, based on fan-efficiency and airflow to the nozzle / heater.

  399.    *   Heater: 40W, Fan: 0.1A * 24V = 2.4W, eff_fan = 0.8
  400.    *   Kf = (2.4W * 0.8) / 40W * 255 = 12.24
  401.    *
  402.    * Fan-speed dependent compensation
  403.    * --------------------------------
  404.    * 1. To find a good Kf value, set the hotend temperature, wait for it to settle, and enable the fan (100%).
  405.    *    Make sure PID_FAN_SCALING_LIN_FACTOR is 0 and PID_FAN_SCALING_ALTERNATIVE_DEFINITION is not enabled.

  407.    *    drop goes away. If the temperature overshoots after enabling the fan, the Kf value is too big.
  408.    * 2. Note the Kf-value for fan-speed at 100%
