I need a cnc shield with 6 axes but I haven't found it online.
I saw in a video of which I attach the link GrblGru: https://www.youtube.com/watch?v=zuDK-uluB6g that the author connected two protoneer cnc shields to an arduino mega, but from the video it is not clear how they were performed links, is there anyone who can help me, maybe pointing me where to learn more?
Thank you
