What is the problem?
I try to connect my Ender 3 printer to OctoPrint and it refuses to connect.
What did you already try to solve it?
I have tried many different ports, updating drivers, using different drivers, updating bit rate, pretty much everything I could find.
Have you tried running in safe mode?
No I don't get how to run it in safe mode, I dont think this would solve the problem anyways as I have tried in two other slicers and they have refused to connect as well.
Did running in safe mode solve the problem?
Did not try.
