I am considering replacing the Mazak controller on my Impulse 30 with an aftermarket controller. The Mazak controller does everything I need except has very limited memory. Not enough memory to do any 3D profiled parts. I am also finding that this Mazak controller is an orphan and there is no information about it anywhere. And there is the problem I posted where it does mystery stuff which has made me lose trust in it! https://www.cnczone.com/forums/g-cod...=1#post2403026. Also some of the modern features like probing and tool height setter would be nice.

I don't want a PC based machine controller. I would be OK with a PC based user interface. All I have really been able to find that seems like it would be capable and affordable is a Centroid controller.

I think the machine has AC servos and has a servo driven spindle.

Does anyone have any other suggestions for suitable controllers and what I need to know about a retrofit?
