All the hard work is done! If you have a 4x4 or larger you can use an electric scribe ($15) or an air scribe ($250-400). There are a couple of outputs and if you get on the Sheetcam mailing list there is also a plug-in for the scribe thats FREE. If you have a smaller than 4x4 there is an output that can be used for a single selenoid for air.
