BL Touch Z-Probing Issues
I have a BL touch I am trying to get running on my Stacker S4 and it is not working properly. I can send gcode to it properly (the M340 commands work fine). When I home z though, if the pin is not already down, it doesn't go down and the probe doesn't work. Here is my configuration.h

What exactly am I missing or doing wrong? The Z endstop that was replaced was the Z-min.

I have a working Prusa style printer with BLTouch on it.
Here is the Configuration.h known to work with this printer: https://raw.githubusercontent.com/alexsomesan/Repetier-Firmware/ramps-tmc2130/src/ArduinoAVR/Repetier/Configuration.h
Please have a look at that one and compare with yours. I will try to do the reverse and spot your problems when I get a bit of time.
Let me know if you spot them before.

I found a site to find the differences for us. Just copy and pasted.
https://www.diffchecker.com/diff ;
alot of differences. not sure what is important or not.
