Okay I turned the tool display off, I traded computers, I added memory, I rebooted the computer between each little run, still the &*!*( stops randomly distroying hours and hours of work. My machine has no Z limit switch so I can not store offsets, my tool height touch plate or manually is not accurate enough to pickup exactly where it left off when it does this stupid ethernet lost communications problem.
My only conclusion at this point after weeks of effort, at trying everything under the sun, is the ethernet smoothstepper is not a viable product for large milling!
