allows you to interact with all your printers via the Cloud, and many other exciting new features.
I VERY MUCH appreciate everyone's feedback so far. At this point in my project, I can wire it anyway I like, but do prefer taking advantage of what I've done so far as originally pictured, all 4 in parallel.
If I am starting to understand this a bit more, I am looking at adding a 2nd 9v battery and clipping them together for 18v of supply. Using that info, this config in the attached new pic is most desirable for me. Does it look correct?
