**What is the problem?**This was all workinng well for several months then yesterday when attempting to load directly from PrusaSlicer to the OctoPrint server I got no response. At octoprint.local I could see that the printer was not connected and I kept timing out when trying to connect. The terminal screen showed
Send: N0 M110 N0*125
Recv: Command not found!
What did you already try to solve it?
I don't really know how to do much. When I reboot the Rpi the Prusa reboots so there is some connectivity. Booting in SAFE mode did not help.
On my browser at octopi.local I can see the webcam feed but not printer specific info like temperature and the status of the printer is DISCONNECTED
Logs (syslog, dmesg, ... no logs, no support)
I can't figure out how to get the serial.log from the Rpi but it is the same as the following screen grab from my browser:
Changing monitoring state from "Offline" to "Opening serial connection"
Connecting to port /dev/ttyACM0, baudrate 19200
Changing monitoring state from "Opening serial connection" to "Connecting"
Connected to: Serial<id=0xaf0b1e50, open=True>(port='/dev/ttyACM0', baudrate=19200, bytesize=8, parity='N', stopbits=1, timeout=10.0, xonxoff=False, rtscts=False, dsrdtr=False), starting monitor
Send: N0 M110 N0125
Recv: Command not found!
No answer from the printer within the connection timeout, trying another hello

There was a timeout while trying to connect to the printer
Changing monitoring state from "Connecting" to "Offline"

Additional information about your network (Hardware you are trying to connect to, hardware you are trying to connect from, router, access point, used operating systems, ...
