What is the problem?

I'm a first time octoprint and raspberry pi user, and I'm currently having trouble with connecting my printer to octoprint. I tried plugging it into pronterface but windows just said unkown usb device.

What did you already try to solve it?

Reflashed octoprint on a diffrent sd card -> nothing
Use ssh to enable the /dev/ttyS0 option in serial port -> no luck
Tried diffrent usb cables and use a known working data cable -> still nothing
Use the electrical tape trick on the 5v pin of the usb cable -> nothing

Have you tried running in safe mode?

Yes

Did running in safe mode solve the problem?

No

Systeminfo Bundle

You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

Additional information about your setup

OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible

ender 3v2 with jyers ui, raspbery pi zero 2 w, chrome and I'm on windows

If you not see me replying to your comment then i'm sorry because im living in south east asia so there is a different in my active time

Hello baobao,

looking at the URL, can you see why this is a useful link for you and no one else?

baobao178 · February 24, 2022, 12:54pm

Omg I'm sorry i forgot that the link is to the octoprint sever
here are thi file
octoprint-systeminfo-20220224125323.zip (179.9 KB)

That worked
OctoPrint tries repeatedly to find a working serial connection but the OS has nothing for it.

Sometimes it helps when there is no sd card in the printer or, the other way round. So please try it with and without a sd card in the printer. Sometimes it makes a difference whether the printer is powered when connecting so please also try this both ways.

And after that, ssh into the the pi and read the kernel messages about it all by:
sudo dmesg

Please copy the output of that up here (as preformatted text so it's easier to read)

What printer model are you using?

here ae the result i got sorry idk how to copy it as preformatted text, and i'm using an ender 3v2

2 ways and you can still do it editing your last post:

use the option in the edit window with the </> - icon
put code fences on a line before the start and after the end of the listing (three back ticks each)

anyway, there is not a trace ofyour printer registering an usb connection with the raspi.

Ender v2 making problems to connect is something many users report, the archives are full with threads about it. I suggest you make use of the search tool here and spend a while reading prvious cases. Often this is a very helpful way to look at one's own situation and what could be tried and done.

Did you try connecting with or without an sdcard in the printers sd-card slot?

Ahmed_Badran · April 23, 2022, 5:57pm

hello did u solve ur problem as i already has the same one

planetar · April 23, 2022, 7:40pm

hello Ahmed,

pls try the search, this may well let you find a solution. Else please open a new Get Help - thread with your description and systeminfo.
Appending an old thread wont let you find the attenton you hope for.

Ahmed_Badran · April 23, 2022, 11:33pm
