On the plus side, my cnc computer died a week or so ago and I replaced it with an old one I had here with windows 7. Since that computer doesn't have a printer port, I use an adapter. I think it is called a UC100. Anyway, I had to reinstall mach3 and go through all the issues with getting it to work with ports and pins and home settings and motor speeds...blah blah blah. One thing that now works is my auto zero touch probe, which I haven't been able to use for a year or so. Now I need to make something with it.
