/**
* 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<offset> Y<offset> Z<offset>'.

// Z_DUAL_ENDSTOPS is a feature to enable the use of 2 endstops for both Z steppers - Let's call them Z stepper and Z2 stepper.
// That way the machine is capable to align the bed during home, since both Z steppers are homed.
// There is also an implementation of M666 (software endstops adjustment) to this feature.
// After Z homing, this adjustment is applied to just one of the steppers in order to align the bed.
// One just need to home the Z axis and measure the distance difference between both Z axis and apply the math: Z adjust = Z - Z2.
// If the Z stepper axis is closer to the bed, the measure Z > Z2 (yes, it is.. think about it) and the Z adjust would be positive.
// Play a little bit with small adjustments (0.5mm) and check the behaviour.
// The M119 (endstops report) will start reporting the Z2 Endstop as well.
