Hal_core is a lightweight cnc and robot controller in progress. It uses mature kernel technologies based on hal. It makes advanched usage of high end c++ libraries to do advanched calculations in realtime.

Hal-core is written as a universal program where all kind of kinematic models are welcome.

Multiple machines can be controlled at the same time. Every machine may load a gcode file.

To get the latest source code just download the latest release tar.gz archive. This archives are pre-compiled for linux amd64. To recompile yourself: After the installation as discribed below, you can overwrite the /opt/hal-core directory with latest archive files and eventually you can perform a recompile fron the /opt/hal-core top dir, requesting the make file.

A hal environment can be used as platform to run realtime applications like:

	motion controllers 
	robots
	cnc-machines 
	parport, ethercat applications
	research and development 
	scientific projects
	building control systems

Included hardware drivers:

	beckhoff, rpi4 ethercat compatible
	mesa ethernet compatible
	parport compatible

Hal-core can interact with high end software packages like “qt”, “kdl kinematics”, “opencascade cad”, “ruckig trajectory”, “hal view”, “cam” etc. Therefore consider to install these software packages before installing hal-core.

Hal-Core install including subprogram “ethercat bus, qt, kdl, opencascade, halview, cam” :

	$ wget https://raw.githubusercontent.com/grotius-cnc/hal-core/main/install_guide
	$ chmod +x install_guide
	$ sudo ./install_guide
	
	# Set user permissions /opt dir.
	sudo chmod -R -f 777 /opt

	# Change owner /opt dir
	sudo chown -R $USER /opt

	# Change group /opt dir
	sudo chown -R $USER:$USER /opt

Run / test hal-core in terminal :

	$ /opt/hal-core/./runtest

Run / test hal-core with halview :

	$ /opt/hal-core/./runtest_halview
