Thanks for the replies!
Tom, that is an idea for sure!
Craig, I can totally appreciate your process of helping me learn vs doing it for me. I am willing to learn however I'm a slow learner with the code.
If it were Arduino, I could hobble something together just fine. I know what needs to happen in the tool change process, I just do not know the Lua words. There are easily defined tutorials. With Lua everything I have come across is to create programs, and user interfaces, and way more technical stuff. None of the terminology makes any sense, and the tutorials go straight into randomization, UI, etc... and none of it really is pertaining to my issue. I have looked for other tool changer examples and haven't found any I can work from.
