You may try an USB memory stick with dmesg if that is recognized.
I dont have any usb connection through my pi. Has it to be usb cable connection between pi and 3d printer?
I thought sharing the same internet connection will be enough.
on my pi there is a USB cable connecting the Pi4 to the mainboard on the ANET A8, it uses this to send the commands to the printer
is it(usb cable) enables also connect through octoprint?

I connect to the PI over wifi to connect to octoprint, then there is a USB cable which is used by octoprint to send the Gcode commands and read the data like bed and extruder temps from the printer

Unless your printer is uber fancy it won't support wifi printing hence why octoprint exists. You can connect to octoprint using the internet and the pi then talks to the printer over USB allowing you to experience what seems like wireless printing. Your printer will almost certainly have a mini or microusb port, you simply need to use a cable to connect this to the pi.
The port in between the one the cable is being plugged into in the photo and the power button is the port you need to use

Oh i am so dumb, thanks for help. I will try connect between pi and printer with USB to USB cable because I didnt see any other port beside the power port like in the photo. I will write the conclusion tomorrow.

we all do these sort of things, it a real learning curve at times
I have had my printer a year and still learning things about different materials etc and things I can do with octoprint, Cura etc
Even I've connected printer and Rpi with usb to usb cable,I'm still getting same kind of errors.
I used usb 2.0 output. I've also checked dmesg again.

This is the Terminal tab when I've try to connect.
Connecting to: /dev/tty1
Changing monitoring state from "Offline" to "Error: Connection error, see Terminal tab"
Unexpected error while connecting to serial port: /dev/tty1 SerialException: '[Errno 13] could not open port /dev/tty1: [Errno 13] Permission denied: '/dev/tty1'' @ comm.py:_openSerial:2611 (hook default)
Why is it still denying access?
I've also tried ''ttyUSB'' or ''ttyAMA0'' things.
Pretty much that dmesg output means that Raspbian and the Pi can't see your plugged-in printer as a device. Assuming that the printer is plugged in and you've got a data type of serial cable then I'm not sure what to tell you. If Raspbian can't see it, OctoPrint can't talk to it.
As I understand from the forums, this problem became nightmare of the users. I haven't seen anybody that faces problem like me and managed to solve it.
It helps to indicate "Ultimaker 3 Extended" when searching the Internet, btw. This forum area seems to include a number of people who have theirs working both from the Cura plugin to OctoPrint and from OctoPrint itself. You might ask them there.
tty1 is a tty on your pi itself, not a printer. It should show up as either ttyUSB0 or ttyACM0. If it doesn't because the underlying operating system doesn't even recognize the printer as a serial device (which your dmesg output looks like) then there is absolutely nothing I can do about it. I strongly suggest following the suggestion of @outsourcedguru and seek help from people who actually own the printer and have gotten it to work with OctoPrint. I'm not one of them and apparently no one here is either. I'm not even sure if the UM3 by default even does support a regular serial connection or if you might need to have to modify it somehow, I remember it having its own thing.
And please do not open bug reports on the tracker for what is obviously a clear support request.
I've found the problem. Ultimaker 3 series does not work with OctoPrint because of disabling USB slave relation.

People seem to think that between cura and the ultimaker cloud you shouldn't need octoprint for remote control https://github.com/foosel/OctoPrint/issues/2288#issuecomment-543739609
Guess ill never get Octopi working ever again?
I ran into the same thing!
I think you can do
sudo usermod -a -G tty yourusernamehere
sudo usermod -a -G dialout yourusernamehere
found on Octoprint on Kubuntu - Permission Denied /dev/ttyUSB0 - #2 by jneilliii
