I originally had a launchpad based controller on my mill, which, whilst it worked - was never 100% reliable. And I could never get the tach to work on it. Aaaand it was a bitch to upload the firmware using my Mac and OSX. So I completely re-did my controller with Arduino Unos and prototype boards, as per Yuriy's instructions over on his website.

The Arduino is mounted on some hex standoffs epoxied into the case, and the the protoshield just mates with the Uno. All of the axis, tach & bluetooth feeds are terminated with plugs to allow assembly to be easier. The sensor connections to the outside world are all circular 4 (or 3 pin in the case of the tach) locking connectors.

9V supply comes in from the bottom, and there's a USB connector for upgrading the firmware if needed. The bluetooth module is attached to a small rail that clips in place over two of the lid fixings.

There's a reset button on the front - and you can see the circular connectors down one side. The USB is on the other

I'm running the latest and greatest firmware / arduino sketch from Rysiu's Website. V5.11 at the time of posting.
If any one is interested, I can post up a bill of materials and links to the components I used. They will all be UK suppliers though as I'm over here in Blighty.
