  462.  * "duplication mode" it can print two identical or X-mirrored objects simultaneously.
  463.  * The inactive carriage is parked automatically to prevent oozing.
  464.  * X1 is the left carriage, X2 the right. They park and home at opposite ends of the X axis.
  465.  * By default the X2 stepper is assigned to the first unused E plug on the board.

  470.  *       results as long as it supports dual X-carriages. (M605 S0)
  471.  *

  473.  *       that additional slicer support is not required. (M605 S1)
  474.  *
  475.  *   2 : (DUPLICATION) The firmware moves the second X-carriage and extruder in synchronization with
  476.  *       the first X-carriage and extruder, to print 2 copies of the same object at the same time.
  477.  *       Set the constant X-offset and temperature differential with M605 S2 X[offs] R[deg] and
  478.  *       follow with M605 S2 to initiate duplicated movement.

  480.  *   3 : (MIRRORED) Formbot/Vivedino-inspired mirrored mode in which the second extruder duplicates
  481.  *       the movement of the first except the second extruder is reversed in the X axis.
