when I press connect in the octoprint web server, to connect to my printer it tries to connect but doesn't succeed.
What did you already try to solve it?
enable wait for start on connect option, get an otg data cable, correctly power the raspberry pi
run "dmesg" in ssh to see if the printer was seen by a usb driver, (it was). manually add the usb port to octoprint. manually set the bouderate and USB port in octoprint.
Have you tried running in safe mode?
Did running in safe mode solve the problem?
You can download this in OctoPrint's System Information dialog ... no bundle, no support!)
