What is the problem?
It seems the PI zero doenst connect to the printer
Connecting to: /dev/ttyAMA0
Changing monitoring state from "Offline" to "Opening serial port"
Connected to: Serial<id=0xaf80ac70, open=True>(port='/dev/ttyAMA0', baudrate=115200, bytesize=8, parity='N', stopbits=1, timeout=10.0, xonxoff=False, rtscts=False, dsrdtr=False), starting monitor
Changing monitoring state from "Opening serial port" to "Connecting"
There was a timeout while trying to connect to the printer
Changing monitoring state from "Connecting" to "Offline"
Connection closed, closing down monitor
I have followed all the instructions https://help.prusa3d.com/fr/article/octoprint-building-an-image-for-raspberry-pi-zero-w_5556
make two raspi zero W but nothing happens
I activate the debug on logs but there seems to be no error message to work with
What did you already try to solve it?
I installed different versions of octopi, upgrade the soft both from octopi and the raspi, reinstalled the last version of prusa firmware, and still the same timeout message
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, what kind of hardware precisely, ...)
