mechanics to move in 2 direction without moving the steppers motor,
by calculating the movement with Math: Pythagoras formulas giving 3 input: X Y Z is possible to give exact coordinate in a Room, also imaginary Points in air if we use 2 of them and make them cross.
If the RED part on top is taken off, we can move X and Y axis 360 degree.

* NEMA 17 or any 5mm shaft motor.
* M3 screw
