Hi Craig,
I also have been saving out separate files for each tool, and even each operation sometimes. Looks like I need to clean up my code and understand what it is doing on a deeper level. I've found a way to turn off all M6 and G43 commands. I've just completed a new enclosure for my cnc and will be testing soon. Thanks for all your help. It will be such a relief to not worry about my Z changing all the time!
Thanks,
Ben
