Steve, It is looking good! The wires do start to get unmanageabe. It is kind of like the wires behind a component rack - it is a bit of an art to keep it all looking nice.
I received your PM regarding the limit switches. When the mask is opening to its widest setting, the mask has to first trip the reset switch and hold it down and then hit the zero switch (while the reset switch is still held down). In other words, the reset switch is tripped every time your masking goes to the "zero" position. (The controller only recognizes the reset switch if you have pressed the reset function on the remote control. If you have not pressed the reset combination on the remote, the controller ignors the reset switch when it is tripped.)
Keep up the progress! I'm anxious to see your completed setup.
