@Phaedrux I have posted all the files you requested. I'm sorry it took so long.
-
Is this a genuine BLTouch or a Creality version? The wiring is a bit different between them. Compare here: https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_connecting#bltouch
Regardless, your config looks ok, so I suspect either a wiring issue, or the probe itself isn't working.

@Phaedrux I had a bad cable. All is well with the BLTouch. Thank you
