When I try to connect to my Prusa MINI+ through Octoprint, I get a message "Could not write to serial port" when using "/dev/ttyAMA0". Setting all options to AUTO gives me a message "No serial port found".
I have a RPi 3B running the latest stable version of Octoprint. I have tried adding serial ports:
- /dev/ttyAMA0 - only this one seems to accomplish anything
I ran through the OctoPrint can't connect to my printer help page. When I view the results of the
dmesg command in terminal, I don't find any similar lines. I only find a single reference to ttyAMA0, but it's not in reference to USB.
Does that mean the correct serial port is just not exposed at all?
Yes. I get the same results.
