Where are you located? Wincnc is a great controller. I have an older 4896 shopsabre also. I think wincnc has an agreement with shopsabre that all controllers and parts go through shopsabre for new machines. If you have the box with the drivers for the motors, then all you need is a pc with wincnc installed. It is a pci card that plugs into the motherboard of the pc. Then a printer cable goes from the card to the box with the drives in it. I have dealt with Kelly at wincnc with good results. You can download the wincnc manual online and it explains everthing about what it can do, along with how to. I would contact wincnc, as they do make and sell computers that work well with their components. shopsabre has answered a few questions for me without support on my second hand machine. I do understand them wanting money to babysit new customers, but the all or nothing approach is not good in my opinion.
