Z Probe removable module - for manual leveling E3D

I don't like idea of calibrating leveling every time before printing.
- Glass bed is usually very stable after one calibration
- Auto correction takes controllers CPU time to correct Z values and decrease printing quality and speed.

My idea is to make perfect calibration once, with glass bed, fix it, and check its leveling after some time.

This module allows you to make level calibration as perfect as possible by using Bed height map option of Repetier-host.
