I've been having issues with the probe rack positions changing after shutting down and rehoming the machine. The rack shifts about 1-2mm from where it was calibrated. I've been looking for the tool.dat file but I can't find it. I'm running 2018 R2. I read that it can be an issue with the tool.dat file or the machine's home changes and will throw off the position every time the machine is homed.
I used to run into this problem because we didn't have the proper permissions to write to the toolc.dat file, so everytime we restarted the demon it would revert back to an old rack alignment. Your IT department might have your permissions restricted.
