// Enable this for dual x-carriage printers.

// prevents hot-end ooze contaminating the print. It also reduces the weight of each x-carriage
// allowing faster printing speeds.

  // Note: the first x-carriage is defined as the x-carriage which homes to the minimum endstop;
  // the second x-carriage always homes to the maximum endstop.
  #define X2_MIN_POS 80     // set minimum to ensure second x-carriage doesn't hit the parked first X-carriage
  #define X2_MAX_POS 353    // set maximum to the distance between toolheads when both heads are homed

  #define X2_HOME_POS X2_MAX_POS // default home position is the maximum carriage position
      // However: In this mode the EXTRUDER_OFFSET_X value for the second extruder provides a software
      // override for X2_HOME_POS. This also allow recalibration of the distance between the two endstops
      // without modifying the firmware (through the "M218 T1 X???" command).

  //                           as long as it supports dual x-carriages. (M605 S0)
  //    Mode 1: Auto-park mode. The firmware will automatically park and unpark the x-carriages on tool changes so
  //                           that additional slicer support is not required. (M605 S1)
  //    Mode 2: Duplication mode. The firmware will transparently make the second x-carriage and extruder copy all
  //                           actions of the first x-carriage. This allows the printer to print 2 arbitrary items at
  //                           once. (2nd extruder x offset and temp offset are set using: M605 S2 [Xnnn] [Rmmm])
