Hello, I saw the link you posted on Universal Controller from Bart Drings.
... Thank you for this info. I am going another route as I do not know anything about GRBL as of today. Seth P.S. I tried GRBL a while back w/ the BBB but came up empty. Anyway, I will keep up w/ my promotion of people looking around to get the motor controller boards made for the BBB/BBAI.
