skr mini e3 v3 z homing fails and nozzle crash with bed Help me please!

[Juanma2k]

Hi all!

I install a skr mini e3 v3 in my Creality CR-10s replacing the old creality board. I have in my printer a 3d touch sensor (bltouch clone).

I configure a compile the skr mini e3 v3 TH3 unified firmware for CR-10s printer here

On z-homing or auto home, it seems that the probe does not detect when it touches the bed and the z axis advances inexorably until the nozzle crash with the bed and does not stop until I unplug the power supply.

Steps to reproduce:

1. Replaced the old original board with the new SKR mini E3 V3.0
2. Installed the 3d Touch
3. Removed the original Z-EndStop switch.
4. Installed the unified firmware
5. Press Auto-Home

3d touch connected correctly to 5 pin connector.

I have also tried to connect the black and white cables in the two possible positions to the z-endstop port with the same result.

I'm desperate, please help me.
