I had the aviation connectors on my Shapeoko and they worked fine, but it wasn't in constant use either. I just want to hook up the thing and not have to worry about it...LOL.

Being able to easily swap to different controllers to see if it is a wiring/motor issue or a controller issue is nice. There have been times when I have moved my machines around and having everything hard wired was a bit of a pain, if you control box is part of you machine and you just need to disconnect a usb or serial cable I guess this is less an issue. I have 3 different controllers, I am planning on wiring the other 2 in the same configuration so I can swap them out if needed.
