Is it possible to have a timer set up for a button so as when pressed it will count down for 3 minutes and display the countdown, so as you know how long it has to go? (see pic)
Or I suppose more importantly display how long the machine has to dwell, if for example G04 P30000 is in the program, it will display 3:00 and count backwards whilst dwelling.

I guess you would need to know where and What the Dwell perameter is called, (where the value of the dwell is stored, and its name if it has one).

Then use that value once the Dwell LED becomes active.
I have tried Settimer(0)'s and the Minute functions, but they really dont give what you want.

I think this is a Brian or some other VB guy........  I hit the wall on it, no luck.
