CNCjs pendant to control CNC machines using joysticks. Written in Python.

The following combinations have been tested and verified to work

The pendant requires Python 3.7+ to work, and has been tested on Linux only. Make sure this is installed in your controller device. You also need a joystick to use as a pendant, so far only PS3 joysticks have been tested. Make sure the Joystick can connect to your controller.

When these are done, clone the repository using your favorite git clone command.

If you are using poetry, you can install the dependencies by running inside the repository folder

$ poetry update

Otherwise, you need to install the library dependencies manually:

pip3 install PyJWT python-socketio[asyncio_client]==4.6.2

You can run the pendant by executing the pendant.py file inside the repository. A config file will be created the first time the script is executed.

We recommend using crontab to start the script after reboot. If you are using the pi user of a Raspberry Pi, just run crontab -e and add the following line to it.

@reboot /home/pi/cncjs-py-pendant/pendant.py >>/home/pi/pendant.log 2>&1

Any other method like creating a daemon and starting it also work. Just make sure whichever user is running it has access to the joystick files, in Linux these are /dev/input/js*
