What was the function of the failed board?

There again, for $300 you could throw a full PC and EMC2 at the problem.[/quote]

That's what I was thinking, for about that much I could have something that would be more flexible and probably be easier for the operator to use. The old setup was not very user friendly and was very difficult to program. While it did have some interesting features for calculating picture frame sizes and counting numbers and sizes of parts cut, but the difficulty in using them meant those nifty features were never used. It was often all the operator could handle just to be able to get it to move to the right position to make one cut.

If you wanted to make a frame for a 5x7 picture using molding that was 1.5 inches wide, it would cut 2 pieces of molding 8 inches long and two 10 inches long. It was far easier for the opperator to do the math himself and cut the sizes he needed then try to program in the molding width, picture size and number of frames needed to let the control do it.

Might also look at ncggui.

Could be set up for straight length cuts or run a formula to calculate the length. Just punch in the numers and go.
