Axis Cloning

Many hobby gantry type CNC machines use 2 motors on Y axis. This prevent the bridge, that holds X and Z axes from driving from one side.
Rabbit Grbl can help with this because any axis can use 2 motors.
You need to define a separate step and Direction pin for each motor, in you machine configuration file.
Use the axis letter for one of the motors and the axis letter plus a 2 for the other one.
Example:
#define Y_STEP_PIN GPIO_NUM_25
#define Y2_STEP_PIN GPIO_NUM_27
#define Y_DIRECTION_PIN GPIO_NUM_26
#define Y2_STEP_PIN GPIO_NUM_13
