This is a triple-Z bed levelling design that should work with most cube-style printers that have a moving bed.

With two steppers on the same driver you constantly have to worry about the steppers falling out of sync when unpowered. If you link them then things get a little better but you're in a big mess if you do skip a step or pull over a cable tooth. Dual independent steppers can auto-level along the X axis but you still have to account for Y axis adjustment manually. With triple independent Z steppers tilt adjustment can automatically level your bed in both X and Y automatically.

This design assumes you already have four smooth rods and two threaded rods that are typical in a two motor setup. We'll reuse those and add another couple rods, stepper, and maybe some mounting hardware to come up with a straightforward and reasonably cost-effective triple-Z setup.

Check out a video on the setup here:
