Installing OctoPrint on Void Linux

To get my 3D Printer running, I had to install OctoPrint onto my iBook G4. Most of the commands are adapted from here.

# Dependencies
sudo xbps-install python3-devel
# Login as root
sudo su
# create the new user
useradd -m -G dialout,tty -s /bin/bash pi
passwd pi
# Login to pi user
su pi

Install OctoPrint in Void Linux

All of the dependencies got installed in the Klipper install, so this is pretty simple.

1. make the directory

cd ~
mkdir OctoPrint && cd OctoPrint

2. Setup Python3 venv

python3 -m venv venv
source venv/bin/activate

3. Install Octoprint

./venv/bin/pip install pip --upgrade
./venv/bin/pip install octoprint

4. Create runsv service(runit) direcotry and file

sudo su
mkdir /etc/sv/octoprint
touch /etc/sv/octoprint/run
chmod +x /etc/sv/octoprint/run

5. Edit the file /etc/sv/octoprint/run

#!/bin/bash
export USER=pi
export HOME=/home/pi
groups="$(id -Gn "$USER" | tr ' ' ':')"

exec chpst -u "$USER:$groups" "$HOME"/OctoPrint/venv/bin/octoprint serve

6. Enable Octoprint

sudo ln -srv /etc/sv/octoprint /var/service

Note: Octoprint on Void Linux seems not to support 250000 Baudrate.
