Show "connected" but not connected to the Arduino CNC shield.

Hi!
GRBL default baudrate is 115200
Your TFT set baudrate is 115200
So, your firmware settings is ok!
Now, we need check connect of MKS TFT35 to CNC shield V3
MKS TFT35 AAUX-1 need connect to CNC shield V3's TX RX GND 5V

from TFT35
TX Brown
RX RED
GND Orange
5V Yellow

You need change connect:
MKS TFT35 TX connect to CNC shield V3's RX
MKS TFT35 RX connect to CNC shield V3's TX

ok, success!
Sorry for the stupidity.
ขอบคุณมาก
