I haven't done any work with Mach4 yet. I've been waiting for it to mature a bit more, and I need to know if it (and the motion controller that I choose) will work for me before I spend any money on it, as the motion controller I'm looking at is over $600.
If I do create any Mach4 screens, it looks like I'll need to provide samples for the specific hardware I'll be using, so that the end user can duplicate the actions on their hardware.
There are a lot of threads here with a lot of different examples, but you may need to spend a lot of time going through them all.
