Gees, Jay - that's gorgeous! My hat is off to you!
You know, there are a number of Youtube's that feature this controller but most of them are not really all that useful. I have just now learned more from your video than most of the rest of them combined.
Got an idea for you: Your production quality is quite good. You would be doing the hobby CNC community a great service if you could cook up a start-to-finish demo/tutorial of this controller. There is a great need for it, imho.
Thanks again for some great ideas!
