Jim,
The auction for the Camsoft CncLite, pendant, and motion card contains most of what you need. It does not mention an I/O card and relay rack, but that would also be required and can be purchased from Camsoft.
You should contact Camsoft and ask if the CNC Lite licence could be tranferred to you if you win the auction, and whether you would get the 1 year support starting from when you first ask them a question
I have a sneaking suspicion that the reserve price on the auction is $2500, because that is what it was originally. It is still a good deal at that price, if you get to use the Camsoft licence. There is always the warranty risk when buying at auction, of course.
The other auction for the motion card only, is not so attractive. You would have to buy most everything listed in the other auction anyways. However, this 1730 Galil card requires a PC with an ISA slot, and a full 16" of clear space to fit the long card into a computer. This guy is selling the PC, but doesn't state what speed the PC is, so I would assume it is a slow one. Maybe you would want it, and maybe not. You have to buy the Galil interconnect module later. Whether you think you want the Camsoft pendant is up to you. It has a value near $1300, and has a pulse generator for jogging with. I think you need a 4 axis motion card for this, because you obviously need 3 axis for your motors, and one more for the pendant handwheel input.
I still think you might want to get new motors and drive amps for your machine. By the time you purchase and add encoders to your machine (assuming it currently uses resolver logic for positioning), you'll be quite a few dollars towards brand new stuff.
You did not say how modern your drive amps are? Maybe you have the old "audible whine" type PWM drives? They might be usable yet, but at worst, you could replace them for about $600 per axis.
I would perhaps recommend that you purchase assistance if you are wanting to get up and running quickly. It may cost you a few $$, but the frustration level will be much lower. It depends on your own skills, and time available. The biggest bonus would come if you decide to do additional Camsoft retrofits of other machines in your shop. Then, it becomes quite inexpensive.
First you get good, then you get fast. Then grouchiness sets in.
