Sounds like a ground loop problem, how is the pi and the board powered?
@marcoa131 the board is powered via mw LRS 350 psu and the pi is powered via board's pins for rpi.
I understand that you're connecting the board and the pi through UART and the board is powering the PI because you're using the UART and power pins and that has been working for you. But how were you powering the board and the PI when you were connecting the board via USB?
@marcoa131 same way
I did some experiments with an Ender 3 running klipper using this board and a btt pi, both powered by the same 24v power supply. I had random disconects just like you. I solved it following this guide: https://community.octoprint.org/t/put-tape-on-the-5v-pin-why-and-how/13574 Also make sure to keep the 5v rail jumper on "DC5V" instead of "USB5V".
Hmm, interesting solution, i will give a try, thank you.
A possible solution for you would also be changing the baud rate to 115200
you'll need to compile and reflash klipper to the board, but it has been successfull in my tests.

I have no issues with uart communication
you can also change baudrate with USB connection.
When I setup connection via USB->Rpi 4 it can disconnect random midprint. But when I use UART, everything is working ok. I have tried different usb cables, does not help. It also disconnects until I press reset button on the board. After I press reset it connects normal. So I don't think it is cable issue.
