What is the problem?
Same issue I had here. Everything was working fine. I did the 1.6.1 update. Powered off the Ender to change the bowden. Turned it back on the RPi does not see the Ender.
In the UI, I get:
State: **Offline after error**
No more candidates to test, and no working port/baudrate combination detected.
With only "Auto" as the options in Serial Port.
lsusb does not show the printer connected. Here's the dmesg | tail -n 20

So its not even seeing the Ender in the OS. I thought it could be a Python 2 vs 3 so I ran the upgrade script. No changes.
What did you already try to solve it?
- Different cords
- Different power supplies
- New image (.18 Octopi and 1.5.2 OctoPrint)
- New card
- New RPi
- Connecting with my Win 10 laptop and using Cura does work
Have you tried running in safe mode?
Yes, no difference
Did running in safe mode solve the problem?
No
