I had some problem with the plunges doing electrodes. The problem in that case was the 3R shank I had in the assembly had a hole running through it. I removed the shank from the NC assembly and the problem went away. I had another that the geometry looked OK but the plunge happened until I erased the surface and replace it. The plunge did show up on the wireframe of the cutter path but was hard to see. I now use microsoft word to "find" Z moves that are not within the range of the program. This of course has its limits because of part geometry. Another way to check is to run the verify from the NC code. I have not done that with V14 so I'm guessing it is still an option. So far V14 has not plunged on me. I have always found that Chris W. can get to the real reason things happen if he has the file.
