-===== 2.1.1 Configure the Slave Axis Driver =====
-OpenBuilds BlackBox has a 4th driver (Called Y2 by default) that can be configured as a slave-driver for either X, Y or Z: You can use the Y2-STEP and Y2-DIR Jumpers to select which axis the driver should respond to. This allows you to wire up dual motors, such as machines that have two motors for the Y axis, in a way where each motor can have a dedicated stepper driver.

-=== Dual-Motor Homing Mode (Advanced, not for normal users) ===
-Grbl 1.1h includes a compile-time option to use a second stepper driver to home a second motor on an axis, with a seperate limit switch
-We provide the Jumper to allow connecting the Y2 driver, to the A3 and A4 pins respectively, but refer to the [[https://github.com/gnea/grbl/blob/40eb439bf2afc4c6f3003836c396e183ba72c45b/grbl/config.h#L615-L655|Grbl Configuration File comments]] for details of how it works, and how to enable it.
