MKS tft70 communication problem

[rouhit110]

Hi friends,
My printer (MKS sbase 1.3 & MKS tft70 & Marlin bugfix 2.0) was working properly and there was a healthy connection between the controller and the LCD. I activated MKS PWC V3, which worked properly after that, but after turning it on and off several times, the connection between the LCD and the controller was cut off and I have no control over the axles and thermistors.
Please advise what to do

I found the reason for this problem
I connected the pw-det socket of the pwc sensor to pin 1.29, which is related to the endstop Z+ signal. I also set it up this way in Marlin
#ifndef PS_ON_PIN
#define PS_ON_PIN P1_23 // J8
#endif
#ifndef KILL_PIN
#define KILL_PIN P1_29 // Endstop Z + PIN
#endif
#define KILL_PIN_INVERTING true
//
But when I disconnected the signal wire from this pin, the connection between the controller and the LCD was established
Now I need to find a replacement PIN. I do not know if this PIN should be pwm or digital
