E5P 2 Z axis different number of steps per motor

[Pavelev]

So far, it's a bit difficult for me in the beginning. I don't know what it means to set the probe points and tell Marlin the orientation of stepper Z

#define Z_STEPPER_ALIGN_XY {{10, 190}, {100, 10}, {190, 190}}

How do I set these numbers?
