Using x e y min pins for 3dTouch in a Fysetc E4

Hi, I'm using a Fysetc E4 board, and this board has too few pins to use. Since I use sensorless homing, the x and y min pins are free. How can I use these pins to for example connect the 3DTouch to the board?

I have defined the pin:

#define SERVO0_PIN 35 // SERVO

But when I try it, the 3d touch does not respond, it does not move the tip. Although in my configuration it is still defined:

#define Y_STOP_PIN 35

Because if I comment this line it doesn't compile. I've also tried commenting out the line:

#define USE_Y_PLUG

But there are also compilation errors.

So what is the correct way to disable y min so I can use it for the 3DTouch servo?

Thanks in advance.

Just taking Y as an Example, but X is the same

#define Y_STOP_PIN 35 means you only have 1 endstop pin on Y

If you home to min this is used as the Y-min endstop. If you home to max this used as the Y-max endstop

you need a Y endstop...

sensorless homing still uses this pin.

The Y diag pin is connected to Y_STOP_PIN via the jumper you install. this is how sersorless works

Ie X-Min and Y-Min is not free to use

Thanks for the info. Now I only have to try with the pin of the temperature of the bed.

temperature pins do not go directly to ths cpu, there is circuity in the way, they cannot be used.
