It won’t mirror some of my Eagle files, but will render top and bottom, quite quickly. But, pushing mirror causes the prior render to disappear, but the mirror is never rendered. I am stuck so any advice is greatly appreciated. -Rick
I narrowed the problem down – I was using an RJ45 jack from one of my eagle libraries and it looks like that particular component will not mirror. I replaced that with a different RJ45 jack and it is fine.
Edit:
Another anomaly I experienced was that the milling portion of my G-Code would not run. Upon inspection, I noticed that many of the x and y coordinates in the first 50 or so lines in that portion or the code were not numbers but instead all read “NaN” (presumably Not A Number). I now suspect that the same component that prevented mirroring also caused this problem, as switching components (but changing little, if anything, else in my Eagle design) has also eliminated this problem.
