  459. * Dual X Carriage
  460. *

  462. * The carriages can be used to print an object with two colors or materials, or in
  463. * "duplication mode" it can print two identical or X-mirrored objects simultaneously.
  464. * The inactive carriage is parked automatically to prevent oozing.
  465. * X1 is the left carriage, X2 the right. They park and home at opposite ends of the X axis.
  466. * By default the X2 stepper is assigned to the first unused E plug on the board.
  467. *
  468. * The following Dual X Carriage modes can be selected with M605 S<mode>:
  469. *
  470. * 0 : (FULL_CONTROL) The slicer has full control over both X-carriages and can achieve optimal travel
  471. * results as long as it supports dual X-carriages. (M605 S0)
  472. *
  473. * 1 : (AUTO_PARK) The firmware automatically parks and unparks the X-carriages on tool-change so
  474. * that additional slicer support is not required. (M605 S1)
  475. *
  476. * 2 : (DUPLICATION) The firmware moves the second X-carriage and extruder in synchronization with
  477. * the first X-carriage and extruder, to print 2 copies of the same object at the same time.
  478. * Set the constant X-offset and temperature differential with M605 S2 X[offs] R[deg] and
  479. * follow with M605 S2 to initiate duplicated movement.
  480. *
  481. * 3 : (MIRRORED) Formbot/Vivedino-inspired mirrored mode in which the second extruder duplicates
  482. * the movement of the first except the second extruder is reversed in the X axis.
  483. * Set the initial X offset and temperature differential with M605 S2 X[offs] R[deg] and
