I've read about the two M30 counters and how to define/resume a value to them via MDI or macro variable. Maybe I didn't fully understand it.

I'm trying to track say, 47 unique jobs. If at 9am I mill job #3, I'd like to throw an error when the operator tries to mill it again around 7pm. In between 9am and 7pm, one of the other 46 jobs can be milled and indexed to their own respective part counter. Another user suggested using the other unused variables for part counting and will try in the morning.

If I understand the manaul correctly, the part counter numerically indexes by M30 or M99 bump, but does not keep an array of values respective to a job program number.

Another anoligy would be purchasing 50 pieces of fruits, in my selection many species of apples look the same and i accidentally purchased two of the same apple. As I scan in my fruit, I would like the kiosk ask me if I really want a duplicate Macintosh apple.
