// allowing faster printing speeds.

// Configuration for second X-carriage
// Note: the first x-carriage is defined as the x-carriage which homes to the minimum endstop;

// 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).

// 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])
