/**
 * Dual Steppers / Dual Endstops
 *
 * This section will allow you to use extra E drivers to drive a second motor for X, Y, or Z axes.
 *
 * For example, set X_DUAL_STEPPER_DRIVERS setting to use a second motor. If the motors need to
 * spin in opposite directions set INVERT_X2_VS_X_DIR. If the second motor needs its own endstop
 * set X_DUAL_ENDSTOPS. This can adjust for "racking." Use X2_USE_ENDSTOP to set the endstop plug
 * that should be used for the second endstop. Extra endstops will appear in the output of 'M119'.
 *
 * Use X_DUAL_ENDSTOP_ADJUSTMENT to adjust for mechanical imperfection. After homing both motors
 * this offset is applied to the X2 motor. To find the offset home the X axis, and measure the error
 * in X2. Dual endstop offsets can be set at runtime with 'M666 X Y Z'.
