* 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>'.
