USART 3 on MKS MONSTER 8 V2

[LoloMake60]

Hi,

I would like to have confirmation on the rt and tx usart3 pins.
RX = PD8 and TX = PD9.

Thank you for your confirmation.

PD8 is USART3_TX, PD9 is USART3_RX

Yes, in Marlin and in Klipper.
What I can't get is the wifi to work in Marlin.

Hi,

Maybe that's it.

For me it's works with SERIAL_PORT_1 -1 and SERIAL_PORT_2 1.

[rai0012]

But the wifi works for you

[LoloMake60]

Yes the wifi works but the driver 7 E4 it's disable because the jumper move pd11 to wifi.

I have flash my mks wifi with ESP3D.
But my screen e3v2 not works, RX and TX on PD9 and PD8.
I don't understand!

Let's clarify a bit.
I use marlin I have the dgus screen connected to uart 3 and working, I have the wifi module connected in its slot and it already works for me with flashed esp3d.
