dazp1976 thanks for the reply.
Unfortunately I have already bought a USB board, still waiting for it to arrive.
I have however got a 3 axis parallel board that I bought some years ago and never used it.
Being as I only want to use X, Y and A axis, maybe I can use it and make the boards Z be the A?? Not sure how to do that.
Also not sure how to relate that to the settings in Mach3 as well.
