I'm trying to connect my printer to octoprint but it never does. I've tried changing, the usb port that I plug it into, turning the printer on and off, and unplugging the raspberry pi and plugging the raspberry pi back in. When it doesn't connect, it tells me to look at the terminal tab and it always displays the same message:
Unexpected error while connecting to serial port: AUTO IspError: ''Timeout'' @ comm.py:_openSerial:2661 (hook default)
What does this mean and how can I fix it?
