You need to add #define LCD_SERIAL_PORT {0|1|2|3} To tell it where you plugged it in.
where the number is the serial uart port on your controller.
0 is normally the usb serial port
1 this also probably conflicts since its basically a ramps. same pins as Z-MIN and Z-MAX so cannot be used.
2 on aux4, avalable to use
3 you cant use as it conflicts with other pins. same pins as Y-MIN and Y-MAX so cannot be used.
It s probably #define LCD_SERIAL_PORT 2 , unless you have rewired the end stops to somewhere else and are using one of those.
