Project: Prusa i4 Single Z-axis motor Modification

Why:

1. 100% synchronization of the two z- axes screws
2. No loss in horizontal calibration of the z-axis even when one z-axis screw turned by hand accidentally.
3. Free one z-axis driver for expansions such as a second extruder.
4. Get a spare stepper motor may be?
5. Use the spare stepper (and freed driver) for extra extruder??? (will upload this soon)
