OctoPrint-TFT, a touch interface for TFT touch modules based on GTK+3.
Allows you to control your 3D Printer, like you can do with any TFT/LCD panel, but using OctoPrint and a Raspberry Pi.
These are some of the functionalities supported:
- Print jobs monitoring.
- Temperature and Filament management.
- Jogging operations.
How this is different from TouchUI?
TouchUI, is an amazing plugin for Octoprint, was created as a responsive design for access to OctoPrint, from low resolution devices, such as smartphones, tablets, etc.
Executing TouchUI under a RPi w/TFT modules, presents two big problems, first isn't optimized to be used with resistive touch screens with low resolutions like 480x320 and second requires a browser to be access, consuming a lot of resources.
This is the main reason because I develop this X application to be executed in my 3d printer.
If you are using
Raspbian or any other
Debian based distribution, GTK+3 can
be installed using:
sudo apt-get install libgtk-3-0
OctoPi does not come with graphical environment, additionally install:
sudo apt-get install xserver-xorg xinit
Installation on Raspbian/OctoPi (recommended)
The recommended way to install OctoPrint-TFT is use the
from the Releases page. The packages
are available for Debian based distributions such as Raspbian and OctoPi for
For example for a Raspbian Jessie:
> wget https://github.com/mcuadros/OctoPrint-TFT/releases/download/v0.1.0/octoprint-tft_0.1.0-1.jessie_armhf.deb > dpkg -i octoprint-tft_0.1.0-1.jessie_armhf.deb
Install from source
The compilation and packaging tasks are managed by the
and backed on Docker. Docker is used to avoid installing any other
dependencies since all the operations are done inside of the container.
If you need to install docker inside
Raspbian or any other linux distrubution
curl -fsSL get.docker.com -o get-docker.sh sh get-docker.sh

To compile the project, assuming that you already cloned this repository, just
build target, this will generate in
build folder all the binaries
and debian packages:
> make build > ls -1 build/
If you are using
Raspbian you can install any of the
.deb generated packages.
If not, just use the compiled binary.
The basic configuration is handled via environment variables, if you are using
.deb package you can configure it at
OCTOPRINT_CONFIG_FILE- Location of the OctoPrint's config.yaml file. If empty the file will be searched at the
pihome folder or the current user. Only used for locally installed OctoPrint servers.
OCTOPRINT_HOST- OctoPrint HTTP address, example
http://localhost:5000, if OctoPrint is locally installed will be read from the config file.
OCTOPRINT_APIKEY- OctoPrint-TFT expects an API key to be supplied. This API key can be either the globally configured one or a user specific one if “Access Control”. if OctoPrint is locally installed will be read from the config file.
OCTOPRINT_TFT_STYLE_PATH- Several themes are supported, and style configurations can be done through CSS. This variable defines the location of the application theme.
OCTOPRINT_TFT_RESOLUTION- Resolution of the application, should be configured to the resolution of your screen, for example
800x480. By default
