Hmm, well I've got a plc and a couple expansion boards for it from a previous project that I guess I could use. 255 inputs and outputs will all the expansions.
I've got to get much more familiar with everything before I start tearing into a working (for now) cnc machine. Any suggestions on where to read up on interfacing in general for a VMC?

Thanks all

Matt

My main questions will be interfacing with the servos, spindle and tool changer. Servos are Red Cap Fanuc, spindle is an AC drive Fanuc servo. Yes, this one is a heavy machine, about 9,000 pounds of iron.

General Mach Discussion / Cincinnati Sabre 750 retrofit to Mach 3?

Hello all,

I have a Cincinnati Sabre 750 running an Acramatic 850 control. The hardware is in great shape, and if you know how to talk to the original control it does a good job machining, still has tight tolerances, etc.
However, I can't interface with it easily and still trying to figure out the DNC to drip feed due to lack of space. Also the computer is a time bomb, the slightest thing that goes out can and will cost an arm and a leg.
So, I'm looking to retrofit with something more modern. I was looking at the Centroid systems, but I've been reading lots of negative about Customer Service and bugs lately, someone had mentioned Mach 3 so I though I would stop by and see i anyone
has any experience with converting a large VMC to Mach 3 or if it is more a hobby style controller.

Thanks in advance,

- Matt
