Centroid Acorn Controller - Has anyone tried one?

[DY10CNC]

I understand that the "free" software does 3 axis simultaneously eg X,Y & Z or X,Y & A.

Have you actually tried the Acorn board? (which was the question posed in the original post)

The acorn was discussed recently, and the general consensus was there were better options for less money.

My main concern with it was the limited IO, with no option to expand. 8 inputs don't go very far on anything other than a basic machine.

As was "4-axis" and "Under $300", and any 3 from 4 simply isn't 4-Axis.
I added the information to save others from thinking the price had dropped for the 4-axis functionality :D
