Hello!
My ender 3 pro connects to octoprint and times out after 30 seconds, with the message "No more candidates to test, and no working port/baudrate combination detected.".
I tried with pronterface and it works any ideas?
Octoprint is on a zero rpi 2w
Change sd card and cable
Yes
No

Hello @Nono196962 !
What happened to this?
You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

How many cables did you try?
Try with/without SD card in the printer's SD card slot.
Also try this:
Hi !
I had not seen that the config had not been added sorry.
I tried 5 cables
I tried with/without sd card
And i have tried with the tape on the usb but nothing change
Can you properly connect to the printer from your PC using pronterface ?
BTW: Cutting the power from the Pi is not the proper way to restart it.
Yes i can connect to pronterface with no problem
However, a connection can be established but later it's the printer that denies further communication:

You may put this values:
port /dev/ttyUSB0, baudrate 115200
manually to the Connection settings in hope the connection stay stable.
New error "Unexpected error while connecting to serial port /dev/ttyUSB0, baudrate 115200 from hook default: OSError: '[Errno 71] Protocol error' @ comm.py:_open_serial:3832"
There was a communication error while talking to your printer. Please consult the terminal output and octoprint.log for details. Error: Too many consecutive timeouts, printer still connected and alive?
