I was able to connect with OctoPrint to my MK3S+, but after some time I gen disconnected.
I tried to send Bed temp to set on printer but nothing is happening.
OctoPrint version 1.8.1, OctoPi version 0.18.0, printer, firmware 3.11.0-4955, browser chrome, operating system Windows 11, Raspberry Pi 4B, connected directly onto the EINSY board
There is a lot of communication corruption going on:

Something is probably interfering with the connection. Check all the wiring for issues, and routing of the cables is important to avoid noisy communication.
