So we did a system restore on our machine and now we are having some issues. The machinist was setting up his job and went to probe his tools and they all came up as the positive length of the tool and not the actual distance of the z axis travel. All the tools that were probed before the system restore were saved and are showing the distance of the z travel and not the actual length of the tool. We tried to run a g68 with no tool in the spindle and that didn't work. The spindle doesn't come down and touch the probe. It alarmed out the machine and now we cannot probe any tools. Every time we go to probe a tool now we get an alarm that says "Z surface dimension of the tool probe is unknown". I'm not very familiar with cnc machines so sorry if this thread is confusing. I'm just a maintenance guy.
