CR-10 Z Probe with Servo Arm

This here is a collaboration between myself and @jonathans1212

Its a Z probe designed for the CR-10 which uses a microswitch on an arm that can be moved by a servo.

Initial attemps to amount to the microswitch directly to the servo resulted in inaccurate probing. Jonathan had the idea to mount the microswitch direct to the printer frame. After doing some testing we got phenomenal results. So I thought about maybe we can use an elbow of some sort to move the arm to be stowed between probes.
