Once my GCode is running, I don't like to just stand and watch it in awe, so to speak, the big advantage is I can get on with something else.
If I put in a suitable Macro at stages in the program that require my attention, e.g. a tool change, I would like the computer to signal me when it gets there.
Does Visual Basic have a "beep" facility, and can I flash an LED on the screen. Is this a problem for the "brains"
