[FR] Add documentation for CR Touch #14

Open isaaclepes opened 2 years ago

Description

The pinout for CR Touch probes is not well documented. I wanted to share this information here, because it is the first place people are likely to look for this information in regards to Longer printers.

Feature Workflow

CR Touch Wiring for LK5 Pro

Servo Connection: D7 = Yellow (Signal) GND = White (Ground) 5v = Black (+5v)

Sensor Connection: Z Min Stop Switch Ground = Blue (Z signal) Z Min Stop Switch 5v = Red (GND)

(Note: If Z stop wires are backwards, the probe will appear to work, but the printer will not stop descending the Z axis when triggered.)

I added a CR Touch to my Longer Lk5 Pro. I've done the wiring, designed and printed a mounting bracket. I am just not certain what I need to do next. I am completely stuck. I guess I thought it would be easier to find the information.
