  412.  * spin in opposite directions set INVERT_X2_VS_X_DIR. If the second motor needs its own endstop
  413.  * set X_DUAL_ENDSTOPS. This can adjust for "racking." Use X2_USE_ENDSTOP to set the endstop plug
  414.  * that should be used for the second endstop. Extra endstops will appear in the output of 'M119'.

  416.  * Use X_DUAL_ENDSTOP_ADJUSTMENT to adjust for mechanical imperfection. After homing both motors

  467.  * The inactive carriage is parked automatically to prevent oozing.
  468.  * X1 is the left carriage, X2 the right. They park and home at opposite ends of the X axis.
  469.  * By default the X2 stepper is assigned to the first unused E plug on the board.

  477.  *       that additional slicer support is not required. (M605 S1)

  481.  *       Set the constant X-offset and temperature differential with M605 S2 X[offs] R[deg] and

  484.  *   3 : (MIRRORED) Formbot/Vivedino-inspired mirrored mode in which the second extruder duplicates
  485.  *       the movement of the first except the second extruder is reversed in the X axis.
  486.  *       Set the initial X offset and temperature differential with M605 S2 X[offs] R[deg] and
