reproduceable connection issues on 1.01 with MK3S FW 3.8.1+ MMU2S
I've upgraded from 0.92.3 straight to 1.0.1 and could not ge one successful print on that version.
I'm using a PI3 to run repetier server with the supplied image.
What I'm seeing are multiple flavours of communication errors mostly RX buffer full, oftentimes also printer looses connection - a reconnect of the repetier server gets the printer in a reboot loop. Printer always fails the connection test in printer settings.
Downgrading to 0.92.3 instantly fixed the issue - no connection on the old version at all.
