I left a page in the screen to prove some yet to be determined ATC support.

The next version of UCCNC is supposed to have slot numbers in the tool table to facilitate ATC macros.
Once that version is released, I'll start looking into what I'm going to do.

I don't think it needs to be carousel or linear rack specific, as both do basically the same thing. Unless you want to manually do specific caraousel operations.

Feel free to tell me what you'd like to see. And be very specific.
