From the project

OrangePi CNC shield for LinuxCNC

This repo contains a HW design files for OrangePi CNC shield for making the OrangePi a LinuxCNC machine.

The allwincnc project can be used to do the realtime heavy lifting (stepper control) while the OrangePi does the slower tasks (kinematics calculations,...).

More details about making this all work with a real CNC machine can be found on my blog
