   *
   * 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

 *   A greater range can be achieved by enabling USE_OCR2A_AS_TOP. But note that this option blocks the use of
 *   PWM on pin OC2A. Only use this option if you don't need PWM on 0C2A. (Check your schematic.)

 *
 *   2 : (DUPLICATION) The firmware moves the second X-carriage and extruder in synchronization with
 *       the first X-carriage and extruder, to print 2 copies of the same object at the same time.
 *       Set the constant X-offset and temperature differential with M605 S2 X[offs] R[deg] and
