I followed instructions to update 1.5.0 to 1.5.1. After the updated process finished I tried to connect to my printer. I get this error message:
State: Offline (Error: No more candidates to test, and no working port/baudrate combination detected.)
What did you already try to solve it?
I have tried restarting both the printer and Raspberry Pi 3. I also tried disabling the one third party plug-in I have (The Spaghetti Detective).
Have you tried running in safe mode and if so did it solve the issue?
I tried safe mode but get the same error.
