What is the problem?
If I power up the printer and the Raspberry Pi the same time (or the printer first, the RPi next) then I have serial connection issues in Octorprint. I press the connect button, and check the terminal tab, then I see strange broken messages from the printer, like:
Send: N0 M110 N0*125
Recv: cho:Unknown command: "� "
Sometimes it tries to send more messages, but the response arrives still wrong and delayed for tens of seconds. Sooner or later the RPi gives up:
Unexpected error while reading serial port, please consult octoprint.log for details: SerialException: 'device reports readiness to read but returned no data (device disconnected or multiple access on port?)' @ comm.py:_readline:2793
Please see https://faq.octoprint.org/serialerror for possible reasons of this.
Until this time, it was discussed several times here, but my problem is different:
If I unplug then replug the USB cable between the the printer and the RPi, and then try to connect again, then everything works flawlessly! If I power on the Raspberry first, wait for Octoprint to start, then turn on the printer, then also everyting works perfectly. No issue at all.
But I want to power everyting up at the same time with a smart wall plug, so I DO need everyting to work this way also.
What did you already try to solve it?
- Changed to factory 5.1V PSU for RPi
- Disconnected everyting else from the RPi
- Changed the baud rate in Marlin from 250000 to 115000
- Insulated the 5V pin of the USB plug
- Tried other USB cables: shieleded, and one with a ferrite ring
- Disconnected TFT35 smart display from the printer
- Disabled Bluetooth in config.txt: dtoverlay=pi3-disable-bt
