     *
     * Constant compensation (use only with fanspeeds of 0% and 100%)
     * ---------------------------------------------------------------------
     * A good starting point for the Kf-value comes from the calculation:
     *   kf = (power_fan * eff_fan) / power_heater * 255
     * where eff_fan is between 0.0 and 1.0, based on fan-efficiency and airflow to the nozzle / heater.
     *
     * Example:
     *   Heater: 40W, Fan: 0.1A * 24V = 2.4W, eff_fan = 0.8
     *   Kf = (2.4W * 0.8) / 40W * 255 = 12.24
     *
     * Fan-speed dependent compensation
     * --------------------------------
     * 1. To find a good Kf value, set the hotend temperature, wait for it to settle, and enable the fan (100%).
     *    Make sure PID_FAN_SCALING_LIN_FACTOR is 0 and PID_FAN_SCALING_ALTERNATIVE_DEFINITION is not enabled.
     *    If you see the temperature drop repeat the test, increasing the Kf value slowly, until the temperature
     *    drop goes away. If the temperature overshoots after enabling the fan, the Kf value is too big.
     * 2. Note the Kf-value for fan-speed at 100%
     * 3. Determine a good value for PID_FAN_SCALING_MIN_SPEED, which is around the speed, where the fan starts moving.
     * 4. Repeat step 1. and 2. for this fan speed.
     * 5. Enable PID_FAN_SCALING_ALTERNATIVE_DEFINITION and enter the two identified Kf-values in
     *    PID_FAN_SCALING_AT_FULL_SPEED and PID_FAN_SCALING_AT_MIN_SPEED. Enter the minimum speed in PID_FAN_SCALING_MIN_SPEED
