What is the problem?
Octoprint is unable to connect to my CR-6 SE
I can see the Octopi / Octoprint on my network and connect to it. I am not able to connect to the CR-6 SE to Octoprint. I also have a webcam that is working properly.
What did you already try to solve it?
I have updated the firmware/App for Octoprint/OctoPi.
I have upgraded from 1.4.3 to 2.0.13
Based on what I am seeing and my understanding, the usb port I am connecting to on the printer will not allow a serial connection. I have tried multiple cables. I have noticed that the MicroUSB connection will power the LCD panel if the printer is powered off but would not think that is the issue. No I have not tried to isolate the +5 on the USB...
Have you tried running in safe mode?
Yes
Did running in safe mode solve the problem?
No it did not
