Now I‘m confused. You mean the z-min connector on my mainboard of the cr-10spro, right? My Voltmeter shows me 0V. 5 volts from another source, then connected to the pins of the z-min port show me the 5v. GND of the z-min is like it should be, the signal pin of z-min behaved like the GND pin. If I correctly interpret your statement, 5Volt on the signal pin, then you expect the evaluation of a falby MarcW - General
Currently are the settings of TheTinyMashine Marlin Version 1.1.9BL active. I don‘t know what you mean with pull-ups, and also there are 3 boards in this system active. The mainboard, the PCB at the x-axis and the piezo board. In meantime I‘ve found out, that the optocoupler at the z-pin on the PCB can generate a failure. It‘s getting more and more power an then it set the z-min pin on. I‘ve addby MarcW - General

I tried everything what I could find in WWW or Youtube to get this piezo sensor to work in my Creality Cr-10s pro, but nothing worked. Either the x-axis goes up during homing or it crashed into my bed. Looking at z-min aby MarcW - General
Today a funny and wonderous thing happened. I‘ve updated my printer to the latest version of The tiny machines, a version with bl touch. When I add a bl touch to my printer (with 2-pin shortcut in PCB, other cables directly to the main board) it works fine. Hmm, why? When I connect now the piezo probe, the printer behaves like touching permanently ground. What it the difference between the bl touby MarcW - General
Hello, I‘ve bought a Universal Piezo Z-Probe PCB v2.75 and want it to use in my Creality Cr-10s pro V1. So I started one month ago and I'm still searching the right way to get it work. Before I write down my fails and errors, do you have any experiences with piezo probing in this 3D printer model?by MarcW - General
