What is the problem?
Every new cable works once or twice, then stops working completely. Printer won't connect directly to my computer or to the raspberry pi with any cable I've used.
What did you already try to solve it?
Swap cables, test pi usb ports
Have you tried running in safe mode and if so did it solve the issue?
serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support! Not log excerpts, complete logs.)
I will provide logs if you need but all it says is cannot detect serial port so I doubt any helpful information will be there
Additional information about your setup
OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible
octoprint 1.5.2, ender 3 base software
