What is the problem?

When trying to connect to the printer (CR10v3) i am getting this error:
There was a communication error while talking to your printer. Please consult the terminal output and octoprint.log for details. Error: Printer keeps requesting line 1 again and again, communication stuck

What did you already try to solve it?

Reinstalling OctoPi 0.18 several times.
New firmware on the printer
Tried different USB cables - with and without +5v
Changed baudrate and serial port

Have you tried running in safe mode?

I am not sure how to do that...

Did running in safe mode solve the problem?
