Octoprint-Lcd is a touchscreen interface plugin for Octoprint, designed for the official Raspberry Pi Touchscreen. It is currently undergoing development, and is nowhere near complete, but is very usable on a day to day biases.

Octoprint-Lcd uses Kivy to draw to the screen and handle input in a separate thread.

Stable, fully functioning features

• View status of the printer, including:
• Current state
• Current file loaded
• Temperatures
• Filament usage for the current file loaded
• Time into print
• Time remaining in print
• Total time of print
• Start, stop, or cancel prints
• Control of the printer, including:
• Temperatures with a nice on screen keypad
• Tool selection
• Filament extrude/retract of different amounts
• Motors on/off
• Jog with different step sizes
• Home XY, Z, or XYZ
• Connection and other miscellaneous controls, including:
• Serial port, baud rate, and profile selection for connecting
• Printer and AUX power
• Shutdown of the Pi
• File Selector for files uploaded to Octoprint:
• Shows files in date order, newest at the top
• Shows date uploaded, estimated time, and filament usage
• Allows printing, selecting, or deleting a file
• Status information always present in top right of screen:
• Current state
• Loaded file
• Adjusts displayed information to match printer profile:
• Number of extruders
• Heated Bed temperatures

These features may or may not work depending on state of completion, your system, and other factors

• USB drive hotplug file transfer
• Allows files on a USB drive to be transfered to Octoprint for printing
• Uses udisks2 through dbus to detect USB drive insertion and moutning
• Seems to have permission problems on Raspbian, however it works fine on Ubuntu.

Features to maybe get into a future commit

• Settings in Octoprint settings manager
• Custom buttons
• Terminal tab
• Gcode viewer
• Slicer tab

First, make sure that Octoprint is installed

Rasbian Jessie:

From http://kivy.org/docs/installation/installation-rpi.html:

Install the dependencies:

sudo apt-get update
sudo apt-get install libsdl2-dev libsdl2-image-dev libsdl2-mixer-dev libsdl2-ttf-dev \
  pkg-config libgl1-mesa-dev libgles2-mesa-dev \
  python-setuptools libgstreamer1.0-dev git-core \
  gstreamer1.0-plugins-{bad,base,good,ugly} \
  gstreamer1.0-{omx,alsa} python-dev cython

Install Kivy globally on your system:

sudo pip install git+https://github.com/kivy/kivy.git@master

Or build and use kivy inplace (best for development):

git clone https://github.com/kivy/kivy
cd kivy

make
echo "export PYTHONPATH=$(pwd):\$PYTHONPATH" >> ~/.profile
source ~/.profile

Rasbian Wheezy:

From http://kivy.org/docs/installation/installation-rpi.html:

Add APT sources for Gstreamer 1.0 in /etc/apt/sources.list:

deb http://vontaene.de/raspbian-updates/ . main

Add APT key for vontaene.de:

gpg --recv-keys 0C667A3E
gpg -a --export 0C667A3E | sudo apt-key add -

Install the dependencies:

sudo apt-get update
sudo apt-get install libsdl2-dev libsdl2-image-dev libsdl2-mixer-dev libsdl2-ttf-dev \
  pkg-config libgl1-mesa-dev libgles2-mesa-dev \
  python-setuptools libgstreamer1.0-dev git-core \
  gstreamer1.0-plugins-{bad,base,good,ugly} \
  gstreamer1.0-{omx,alsa} python-dev

Install pip from source:

wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py
sudo python get-pip.py

Install Cython from sources (debian package are outdated):

sudo pip install cython

Install Kivy globally on your system:

sudo pip install git+https://github.com/kivy/kivy.git@master

Or build and use kivy inplace (best for development):

git clone https://github.com/kivy/kivy
cd kivy

make
echo "export PYTHONPATH=$(pwd):\$PYTHONPATH" >> ~/.profile
source ~/.profile

Make sure that the correct python is being run if Octoprint is in a virtual environment (ie OctoPi)

git clone https://github.com/chickenchuck040/OctoPrint-Lcd.git
cd OctoPrint-Lcd
python setup.py install
