   * M605: Set dual x-carriage movement mode

   *    M605    : Restore user specified DEFAULT_DUAL_X_CARRIAGE_MODE
   *    M605 S0: Full control mode. The slicer has full control over x-carriage movement
   *    M605 S1: Auto-park mode. The inactive head will auto park/unpark without slicer involvement
   *    M605 S2 [Xnnn] [Rmmm]: Duplication mode. The second extruder will duplicate the first with nnn
   *                         units x-offset and an optional differential hotend temperature of
   *                         mmm degrees. E.g., with "M605 S2 X100 R2" the second extruder will duplicate
   *                         the first with a spacing of 100mm in the x direction and 2 degrees hotter.
   *    M605 S3 : Enable Symmetric Duplication mode.  The second extruder will duplicate the first extruder's
   *              movement similar to the M605 S2 mode.   However, the second extruder will be producing
   *              a mirror image of the first extruder.  The initial x-offset and temperature differential are
   *              set with M605 S2 [Xnnn] [Rmmm] and then followed with a M605 S3 to start the mirrored movement.
   *    M605 W  : IDEX What? command.
   *
   *    Note: the X axis should be homed after changing dual x-carriage mode.
