Jim,
Ok. I will ask the current owner of the boads in the next few days to see if he is willing to sell them.

For my own interest, Is the problem with your machine a problem that has just happened or has it always had a feed problem?
I have been told that once the batteries to the CNC is removed, the paramaters are lost and it is almost impossible to make it work again.
You would perhaps be in a better position in USA to get help from a FANUC professional to fix the issue you already have. I say this because you will need FANUC help to re-enter the parameters to the new board. By loading your Existing parameters, you may well pass your existing problem onto the new boards.
I know VERY LITTLE about these things to thats why I ask if this is a new problem or and old one.

Hope this helps,
Chich
