Will the mate control produce smooth 3D toolpaths & how much memory does it have? I want to machine some 3D aerospace parts on this machine. Thanks!

the OI-MC control has some lookahead, using g5.1q1, I dont know about the mate control.

I dont know how much memory it has but at work we use a compactflash card to hols our programs. I dont think its a lot because on some of my finer cuts it only runs at 50% feed. You should find that information in your Handbooks that came with your Sharp. And to reiterate on the Oi, to turn on use G5.1Q1 and to turn off is G5.1Q0.
