What is the problem?
Setting up second raspberry pi B+ - installed octopi rel 16, all was well - shutdown pc and printer for several days. powered up PC and printer and am getting the following message when I try connecting to it in Octoprint Error: Failed to autodetect serial port, please set it manual
Please note that my other printer - ENDER 3 is woring with a separate raspberry PI B+ and is having no problems.
What did you already try to solve it?
When to Connections and tried to change it from AUTO but it only let me select AUTO.
Went to OctoPrint setting and also tried changing the serial detection from AUTO - no good
When to Server and tested the Port connectivity check and it testes out fine.
Tried changing the Printer profile thinking that perhaps it had been corrupted but no good.
Shutdown the raspberry PI and replaced the SD card with my backup SD card - no change

Found the problem. Swapping connection cable from working raspberry pi to the one reporting the connection error and it worked. I have a bad cable.
Tried to mark this as solved but I get a 404 error ion the website.
