This project has been archived, but @Z-Bolt has nicely reborn this project at https://github.com/Z-Bolt/OctoScreen; take a look at it! Looks promising.
OctoPrint-TFT, a touch interface for TFT touch modules based on GTK+3.
Is a X application to be executed directly in the X Server without any windows manager, as frontend of a OctoPrint server in a Raspberry Pi equipped with any TFT Touch module.
Allows you to control your 3D Printer, like you can do with any TFT/LCD panel, but using OctoPrint and a Raspberry Pi.
- Print jobs monitoring.
- Temperature and Filament management.
- Jogging operations.
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.
OctoPrint-TFT is based on Golang, usually this means that is dependency-less, but in this case GTK+3 is used, this means that GTK+3 libraries are required to be installed on the system.
If you are using Raspbian or any other Debian based distribution, GTK+3 can
be installed using:
sudo apt-get install libgtk-3-0OctoPi does not come with graphical environment, additionally install:
sudo apt-get install xserver-xorg xinitThe recommended way to install OctoPrint-TFT is use the .deb packages
from the Releases page. The packages
are available for Debian based distributions such as Raspbian and OctoPi for
versions jessie and stretch.
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.debThe compilation and packaging tasks are managed by the Makefile
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
just run:
curl -fsSL get.docker.com -o get-docker.sh
sh get-docker.shYou can read more about this at
docker-install
To compile the project, assuming that you already cloned this repository, just
execute the 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
the .deb package you can configure it at /etc/octoprint-tft-environment.
-
OCTOPRINT_CONFIG_FILE- Location of the OctoPrint's config.yaml file. If empty the file will be searched at thepihome folder or the current user. Only used for locally installed OctoPrint servers. -
OCTOPRINT_HOST- OctoPrint HTTP address, examplehttp://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 example800x480. By default480x320.
Custom controls to execute GCODE instructions and commands to execute shell commands can be defined in the config.yaml file.
The controls are limit to static controls without inputs.
