I HAVE AN ENDER 3 PRO AND I JUST REPLACED THE MOTHERBOARD AND THE SCREEN. I UPDATED THE FIRMWARE TO THE LATEST ON THE TFT DEVICE. I HAVE CHECKED 50 TIMES TO MAKE SURE THAT THE SERIAL CABLE IS PLUGGED IN CORRECTLY, AND I HAVE VERIFIED THE BAUD RATE WITH THE PRINTER AND THE TFT ARE THE SAME. IT WORKS IN MARLIN MODE AND I AM ABLE TO CONTROL THE PRINTER THAT WAY. HOW DO I GET THE TOUCH MODE TO WORK?
