Ender 3 v2 wont connect with OctoPrint!

What is the problem?
Im trying to connect my Raspberry Pi 3b+, im at the step where you are supposed to press connect. Nothing happens really. "just a fail".

What did you already try to solve it?
Swapped usb cables, my thought is somethings wrong with the serial, it says AUTO, nothing more.

Logs (syslog, dmesg, ... no logs, no support)

serial.log (2.2 KB)
plugin_softwareupdate_console.log (11.5 KB)
plugin_pluginmanager_console.log (33.3 KB)
octoprint.log (62.8 KB)

Additional information about your network (Hardware you are trying to connect to, hardware you are trying to connect from, router, access point, used operating systems, ...)

Nothing special, Archer 60 router, fibre network.

Hello @ElectroCat !

When you try to connect to the printer, then it is not a network issue. (I'll change that in the headline)

Can you connect the printer to a PC using pronterface?

BTW: What printer?

Hello,
as OctoPrint can't connect to your printer I wonder what the OS can see of it.

Please ssh into the box,
sudo dmesg -w
and while this is running disconnect/connect again the usb cable.
Please post the output of dmesg here.

This is what i got. all popped up at once before i had my chance to connect my printer

And this is when i ran it, and at the same time connecting my printer nothing happend, it just says the sudo line and nothing more :confused:

Ender 3 v2 4.2.2 board.

As you can see, i just got "connecting..." when i try to use the baud rates, The last one though, gave me an error. (250000). and the others did not.

Have you tried 115200?

I used the ones that showed up, tried single one, one by one. I do not remember 115200 being there, but if it was, i have already tried it. Ill add some screenshots later on when im back from work. I have no trouble acessing my Pi in anyway, just to add. I can get into ssh and all that stuff. so that works "i think".

Should i wait longer for prunt to connect maybe? i gave it a few seconds each just to test

I have my Pi yes. and its connected to my wifi. i used windows 10, command promt to get into the ssh and all that seems to work. Using an SD card into the Pi ofc, with an image and all that stuff

It looks like neither the Pi nor your PC are seeing the printer. Did you get a new device notification when you plugged it into your PC?

Have you tried different USB cables? It's possible that you are using a charging cable, such as one that comes with a phone.

Hi!

That is correct, my PC did not so the notification when i tried to connect my pc to the printer. I tried 2 cables, one that came from a DJI mini drone. and the one from my chromecast. (all my new tech i own is USB-C, trouble finding old ones XD)

Have the community found a cable that is 100% failsafe?

I edited that post you replied to & then deleted it anyway almost straight away, I had misread some of the earlier conversation :man_facepalming:

Any cable that says it works for data transfer should be OK. The best cables are shielded, possibly with ferrite beads. Majority of the time buying an actual cable should be enough, those that are included with various devices that need charging don't often work.

So i should find one for data transfer, and not charging then

Yes, that should work

Ill see what i can find. any tips on where to look? XD in a normal household :stuck_out_tongue:

usb cable of external harddisk for example
any where data transfer is actually needed

@foosel might have an idea about the logs? Anything "obvius" i might have missed? too much for my small brain knowledge XD

Please don't drag me into specific threads, if every user of OctoPrint did that I'd not be able to use the forums anymore due to drowning in notifications. The folks present here are just as knowledgable and gave you some stuff to try already.

Oh okay. Im sorry then. It was just a though. Did mean no harm :confused:

I totally understand that and no offense was taken or anything. It just really doesn't scale with a project of this size :wink:

Solution is found!
After testing 6 different cables, mainly from chargers and mobile stuff. i went and bought one for "media transfer only" and it worked like a charm. Thanks for all the tips though!

Ill add an link to the cable i found working!
Link to the cable: Ekon - Cable with Type A male USB and male micro-USB
