Hello, I just added a capacitive sensor and i use resistor to divide the voltage of hte output signal Then i wired the signal to my ramps and i tested the voltage to check if it was correct, the output voltage was 3.85V which is ok for a ramps/arduino. So i dicided to configure the firmware, but during the configuration it looks like that my ramps or my arduino broken, now it always show the Z endstop open. I checked voltage of capacitor and it's still working. Also it's the second time the issue appear, so i would like to know what am i doing wrong ? Regards, Toggy EDIT i disabled the endstop pullup https://reprap.org/forum/read.php?219,555250,555250#msg-555250 Sun, 13 Sep 2026 13:48:53 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?219,555250,555250#msg-555250 https://reprap.org/forum/read.php?219,555250,555250#msg-555250 I just added a capacitive sensor and i use resistor to divide the voltage of hte output signal
