It will just be for setting up of new things that you will need the programming I would imagine.

The specs of that motor on eBay make more sense, the 74Amps you mentioned before seemed very high but that one says 7.4A.
It seems likely that you have a resolver but having said that it may still be the case that your motor has an encoder if the part number is not the same, usually its only one letter that is different in the part number.

So how would I tell if I had a encoder?

Easy way is to lift off the end cap and see, encoders nearly always look totally different from resolvers. If you take a pic and post it I may be able to say.

Right on. I'll get a pic up ASAP. Hey I was wondering can I get Mach3 to run on windows 7? I want to have it on my computer with bobcad. Or is it a bad idea? Would a dedicated comp be better?

I see there is a whole section about running mach on vista and 7 so nvm on that question. Here are the pics and one of the top of my tool changer/drawbar. It looks like I won't be able to run an encoder on top of that as it probably isn't always engaged.

Mach should run fine on W7, even 64bit when using an external device.

Pics dont really show anything but it is almost a certainty that it is a resolver as they are often geared with antibacklash gears like that, then again I have seen some encoders geared like that..

Either way, this should be a be a very capable machine when it's sorted out. Do keep us informed :)

I'm ready to star tearing into it but I don't really know where to start should I gut it all but the spindle motor wires and servo motor wires?

If you are using the existing drives etc  then I would not touch too much of the wiring as likely you will be able just to wire it in to your external controller.

So I bought the KFlop Kanalog and Snap Amp but it only puts out 80V and my motors r 90V. Tom said it will still work but my max rpm will be lower.
