Hello, I am using a board (Fysetc E4) based on esp32 for a 3D printer. But due to the few outputs of the esp3d I want to use the bed temperature sensor pin to control an endstop. The problem is that the extruder temperature sensor is on GPIO36 and the bed temperature sensor is on GPIO39. I have configured the pins in Marlin, but the moment I connect the endstop to GPIO39, the extruder temperature sensor stops reading. But the reading of the endstop works great.
Is it incompatible to use GPIO36 and GPIO39 at the same time? The endstop I use has several resistors, I assume they will be pullup or pulldown resistors. Can these resistors interfere?
Thanks in advance.
Error in GPIO39 and GPIO36
