UART rx0 tx0 help needed
Hello !
I'm using a ramps FD and an ESP3D wired on RX1 TX1
I also have a Bigtreetech Touchscreen who also want to use an UART Port. Problem is When i connect the screen to RX0 TX0 it doesn't work... I can connect it to RX1 TX1 and esp3D to the screen but as soon as I do that the ESP3D can't be used anymore with repetier host and most of the wireless commands doesn't work anymore.
So this is the 1000$ question :
Why can't I use the port and how to enable communication on my arduino Due RX0 TX0 pins to connect the screen on theses pins and my ESP3D on RX1 TX1 ? (USB who normaly share the pins work like a charm)

But now the screen became crazy with "checksum error" and beeps endlessly
Bluetooth = UART1 => Esp3D
USB = UART3 =>Bigtreetech TFT V3 7"
