I have 3 buttons wired up to inputs 2,3,4 and configured for start, pause, stop and the keyboard and mouse are in a drawer that I keep closed while running code so that it doesn't fill with swarf. It would be really nice if those buttons could be used to respond to dialogs (ie. the Start button == OK, the Stop Button == Cancel). The main use for me would be to respond to tool change dialogs without having to open the keyboard drawer to hit enter (or escape if needed).
I finally installed v2 on the computer that controls my mill today and really like how it is so much more flexible that the last version (which was pretty good as well). The new one is taking a big step up. Loving your work
Cheers
