Hello and Welcome to the forum,
From a huge block of words, this is what I understand you want to use octoprint.
If that is the case then here are some easy steps.
First Part:
- Download and flash krescue from here on your sd card.
- Insert it boot into it.
- Connect lan cable for internet.
- Go to image to emmc and detect check image list and download file with this name
Vim3-ubuntu-20.04-gnome-linux-5.17. (Use remote if you have or connect a keyboard) - Then press install.
- Reboot with sd card removed.
- Now got will not into Ubuntu OS with Gnome Edition image.
** You have a fully working os on your device.
Second Part:
Next you need to follow the steps documented by a user on octoprint forum
In user group command just replace the user name with the one used by khadas, I cannot remember it now
sudo usermod -a -G tty {Khadas_username}
sudo usermod -a -G dialout {Khadas_username}
Ignore the HAProxy section, as you can use the octoprint services just fine with port 5000.
This is not entirely true. Looking at the above installation guide is looks very simple and there is nothing that will not work on Ubuntu 20.04 image.
It is just using upstream packages and pip while auto services are coming from octoprint git.
The reason I advised to use Ubuntu Gnome 20.04 image, cause it is upstream kernel and will be supported for long term. It is build officially by Khadas team and thoroughly tested on Vim3 device.
Let me break down this thread into 2 part for you.
First Part:
Get Ubuntu Gnome 22.04 OS on emmc.
Second Part:
Install OctoPrint.
Trust me you will be surprised with Vim3 performance as it is way powerful than RPI4.
Start the Above mentioned steps and complete the first part then try the second part and if you can stuck anywhere then tag me here in this thread.
Good Luck.
