Auto-leveling using an Inductive Sensor

[ejcruz]

Had another look at the BLTouch specification here's the details:
3 wires: Brown = GND, Red = +5V, Orange = control signal
2 wires: Black = GND, white = Z-Min Axis

FFCP Z-Min Axis connection on the board is as follows:
pin 1 = +5V
pin 2 = GND
pin 3 = GND
pin 4 = signal

First I want to make it clear I have not tried/tested connecting the BLTouch to the FFCP, I hope someone else with more electronic experience will help, the BLTouch has 5 wires whereas the FFCP Z-Min Axis only has 4, so I would first try the following:
BLTouch =========== FFCP
Brown wire (GND) ====>> Pin 2 (GND)
Black wire (GND) ====>> Pin 2 (GND)
Red wire (+5V) ====>> Pin 1 (+5V)
Orange wire (signal) ===>> pin 4 (signal)
White wire (Z-Min) ====>> pin 3 (GND)
The Orange and the white wires I'm not sure they may need to be swapped around.

To test use the following G-Code:
M280 P0 S90 ; to push the pin down
M280 P0 S10 ; to pull the pin up

You need to read the sailfish manual to understand the G-Codes:
- go to section Little Details, then go to Firmware Auto-Leveling
- go to section Special G-Code Commands

Hope this helps
