OctoPiTouchPanel

Touchscreen interface for OctoPrint using the kivy gui framework

The layout is designed for the official Raspberry Pi Foundation 7" touchscreen. I would recommend using the Raspberry Pi 2 or 3 Model B for the Octoprint server. I think the Pi 1 might be a bit under powered for running this touchscreen app.

Installation

Big thanks to Tim Vaillemans for documenting this installation process.

Install prerequisites

Install OctoPi (https://octopi.octoprint.org/)
ssh to your Octoprint server
sudo su -
apt-get update
apt-get upgrade
apt-get install python-pip
apt-get install python-pygame
pip install Cython
pip install kivy (Kivy-Garden is included)
garden install graph

Configure kivy to use the touchscreen input

[Copied from https://kivy.org/docs/installation/installation-rpi.html]
If you are using the official Raspberry Pi touch display, you need to configure Kivy to use it as an input source. To do this, edit the file ~/.kivy/config.ini and go to the [input] section. Add this:

mouse = mouse
mtdev_%(name)s = probesysfs,provider=mtdev
hid_%(name)s = probesysfs,provider=hidinput

Clone this repo

cd /root
git clone https://github.com/matt448/OctoPiTouchPanel.git

Configure OctoPiTouchPanel

cd OctoPiTouchPanel
cp octoprint.cfg.sample octoprint.cfg
edit octoprint.cfg (with vim, nano, etc.)
The important items to edit are in the APISettings section.
- host: should almost always be 127.0.0.1
- apikey: get API key from your octoprint webpage. Looks something like AADDEEDD0BA48F891F3966F856765FB
- nicname: Use ifconfig to identify network interface Looks something like eth0 or wlan0

Starting the app

cd /root/OctoPiTouchPanel
python /root/OctoPiTouchPanel/main.py

or to start the app in the background

python /root/OctoPiTouchPanel/main.py &
