 Our [local hackerspace](http://www.munichmakerlab.de/) has been offered a
 CNC mill, and we've had a few days to play with it.

 As we received it, the machine didn't have endstops, so we added some,
 using microswitches and 3D printed cases to hold them in place.

 I've left out pin D4, which is the Chip Select line to the SD card, as
 well, so I can use the SD card later on.

 Obviously, this is a bit of a chicken-and-egg situation here: to route that
 board, we need the router to work, so I made a few temporary connections
 using breadboard wires.

 With these connections made, it's ready to be powered up. While the
 debugger is connected, pin D0 is going to be driven by the serial port, so
