Please forgive me if I understand something wrong or do something really stupid, I just cannot find any documents since it seems to be a very easy and basic task.
So here's the problem: I recently installed the OpenWRT on a device similar to raspberry pi, on which I run my 3d printer control software. I followed the instructions in this video (from 4:30 - 8:20), however it only shows how to connect via the wireless network. I'm now plugging a camera into the device and the wireless is unstable when trying to stream the images, therefore I'm trying to change the device to connect via wire. I plugged the ethernet cable into the slot, but the device won't connect through ethernet. Any suggestions I need to do next? Thank you in advance.
This should be pretty straight forward, but let's look at your current config to understand the config as it is right now.
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

This is what I got after typing the commands.
This device is not supported by the official OpenWrt project.
It appears you are using firmware that is not from the official OpenWrt project.
When using forks/offshoots/vendor-specific builds that are "based on OpenWrt", there may be many differences compared to the official versions (hosted by OpenWrt.org). Some of these customizations may fundamentally change the way that OpenWrt works. You might need help from people with specific/specialized knowledge about the firmware you are using, so it is possible that advice you get here may not be useful.
You may find that the best options are:
- Install an official version of OpenWrt, if your device is supported (see https://firmware-selector.openwrt.org).
- Ask for help from the maintainer(s) or user community of the specific firmware that you are using.
- Provide the source code for the firmware so that users on this forum can understand how your firmware works (OpenWrt forum users are volunteers, so somebody might look at the code if they have time and are interested in your issue).
If you believe that this specific issue is common to generic/official OpenWrt and/or the maintainers of your build have indicated as such, please feel free to clarify.
I had to look up this Creality WB-01 device because using an OpenWrt box to run a 3D printer is something that haven't crossed my mind. (And I run a bunch of OpenWrt devices and a 3D printer running Klipper!)
Fortunately looks like someone else has already done a deep-dive on the device on Hackaday. Are you using this OpenWrt fork by any chance? Perhaps you are also trying to Klipper on OpenWrt as well?
If that's the case, you should try asking the people behind those projects instead. The fork is more than 6000 commits behind official OpenWrt as of this writing, so until they submit a pull request and get Creality WB-01 support merged we can't really help you with this (or any) OpenWrt fork.

what is the output of ip -o link show?
... and the problem is ...
enable_vlan '0'
so, i was curious about this device, and get one for 10EUR 
initial support made at this GIT have an error
it initialize ethernet in wrong way
yes, we need to use swconfig/vlan to setup eth interface
config switch
option name 'switch0'
option reset '1'
option enable_vlan '1'
config switch_vlan
option device 'switch0'
option vlan '1'
option ports '6t 0'
config device
option type 'bridge'
option name 'br-vlan1'
list ports 'eth0.1'
config interface 'vlan1'
option device 'br-vlan1'
option proto 'static'
as you could see
port 6 is tagged CPU port
port 0 is rj45 on device
tested on 23.05.snapshot
swconfig dev switch0 show
