I have replaced the CR Touch with a Creality 3D End-stop switch. I use only the S (signal) and V (Volt) pins in the 3-pin End-stop switch and connect them S to the motherboard pin that reaches the MCU and the V to the G (Ground) motherboard pin, so exactly as the other X and Y already existing End-stop switch on the printer. However, due to a “Firmware Dependency”, “Safety Feature” or “Configuration Settings” if you want, the Z-axis stop moving after I disconnect the CR Touch. Can anyone give me some directions about the Marlin code modifications needed to achieve this replacement (not to require input from the CR Touch sensor for Z-axis movement validation)? The photo is from an Ender 3 V2, but it fits as it is the same in my 3D printer.
