No serial port found
I have installed Octoprint for the first time and the printer is not connecting to the raspberry pi.
What did you already try to solve it?
I have ordered a special cable. I tested it with my keyboard. It works, it is capable of data transfer.
I have switched the ports.
I have used the dmesg | tail -n 20 command and it sees only my keyboard, and not the printer.
Have you tried running in safe mode?
yes
Did running in safe mode solve the problem?
no
Systeminfo Bundle
You can download this in OctoPrint's System Information dialog ... no bundle, no support!)
Well if it's based on klipper than the external connection approach from a host software like OctoPrint won't be possible. There are special things you have to do inside klipper to allow it to work with OctoPrint, and both the klipper (pi side software) and OctoPrint have to be running on the same device. So if their board can handle it (probably can't) you would have to install OctoPrint on it directly.
