Today, spotted a few feed, speed problems in the CAM feature wizzard. Mis calcs and such. Instead of editing at the feature, I went to the matl library to set new defaults. The matl library opened but with no population, no material catagories nor feeds speeds chip loads. The window with two empty panels. Bob seldom crashes V27, and the OS never crashes. Where is the population stored in Bobs directory and how do I link it back.Is it gon forever even the baseline defaults. If so I do have a somewhat personalized matl library from V26.
