CNC hack evening writeup

Last night we had our first hands-on tutorial in the Yeoman of England.  This one was longer than our lockpicking one done in our very first meet.  Martin kindly brought along his router and a few PCs to control it.  The first was used with his existing setup running Mach3, and the second was used to investigate LinuxCNC/EMC as an alternate controller.
