Working in Ubuntu 18.04 LTS
forked from kevin, how is based on Guide
This guide was created because following the original guide lead to some problems. Plus I wanted Ubuntu running Octoprint and a true webcam stream (not time-lapse photos). Performance is much better than a RaspPI.
Everything was configured in this order from a fresh desktop installation. I chose to autologon my main user because security isn't a real concern here.
some adaptation for TAMI ANAT5 shared printer
First thing's first, update:
sudo apt-get update && sudo apt-get -y upgrade
on TK2 the python3 (3.6) installed is not enough
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt install python3.8-full python3.8-dev
This auto installer is really nice for getting all system drivers.
sudo ubuntu-drivers autoinstall
Add $USER to dialout group allowing USB / Serial access:
sudo adduser $USER dialout
Save .\config-files\50-myusb.rules to /etc/udev/rules.d/50-myusb.rules
Reboot: sudo reboot now
Install latest version, make sure to use your install python like above python3.8:
cd ~
sudo apt update
sudo apt install git libyaml-dev build-essential
mkdir OctoPrint && cd OctoPrint
python3.8 -m venv venv
source venv/bin/activate
pip install pip --upgrade
pip install https://get.octoprint.org/latest
Then exit out of venv and start in terminal with:
~/OctoPrint/venv/bin/octoprint serve
Browse to http://10.82.2.8:5000/
Install with:
sudo apt-get install motion
mkdir ~/.motion
Copy .\config-files\motion.conf into ~/.motion/
Reboot: sudo reboot now
Start in terminal with: motion
Browse to http://system.ip.address:8080 (not localhost)
its 2023, we are using systemd
create the following in /etc/systemd/system/octoprint-deamon.service
[Unit]
Description=Octoprint
Documentation=https://docs.octoprint.org
After=network.target
[Service]
User=ubuntu
Environment=HOME=/home/ubuntu/OctoPrint
WorkingDirectory=/home/ubuntu/OctoPrint
ExecStart=/home/ubuntu/OctoPrint/venv/bin/octoprint serve
Restart=always
then
sudo systemctl daemon-reload
sudo systemctl start octoprint.service
sudo systemctl status octoprint.service
if all good
sudo systemctl enable motion.service
motion has it by default
In OctoPrint, click the settings wrench and find GCODE. Then add these scripts as needed.
If scripts are not defined in the slicer don't forget to add them to octoprint. Also, on start,
don't forget to wait on temp with M190 S70 ;bed temperature wait and M109 S220 ;extruder temperature wait.
It works well after G28 ;home.

If everything was successful, issue a reboot. When the server reboots, OctoPrint should be running at http://0.0.0.0:5000 and a webcam stream should be running at http://system.ip.address:8080
