Actually, I think there are some bugs in the offsets. I've only had one other person notice it in 4 years.
Send me an email, and I'll send you some updated macro's.
To use the ATC, just use your ATC M6Start macro instead of the 2010 M6 Start macro, and it should work fine.
Since you don't need the Initial Auto Zero macro, you can just create your own M881 macro and use it for tool setting. Since the button calls the M881 macro, you don't need to change anything in the screen at all.
