What is the problem?
Can't connect to printer over octoprint. Gives error: Offline (Error: SerialException: 'device reports readiness to read but returned no data (device disconnected or multiple access on port?)' @ comm.py:_readline:2916 also subsequent error after attempting again: Error: No more candidates to test, and no working port/baudrate combination detected.
Printer will freeze and prints will fail if I try to do anything with octopi other than have it watch via the camera.
What did you already try to solve it?
- Replaced USB cord
- Replaced Power supply
- Restarted pi
- Restarted printer
- Manually selected baudrates.
