Oh, don't you just love it when someone has prepared all the software you need for a project and wrapped it up in a tight little package? Well I sure do, and that's why I have made a complete BeagleBone Black flasher image with all the needed software for making a clone of Debrew. So when you have all the parts printed, the steppers installed, the beans in the container, go to this localtion, and download this image:

http://feeds.thing-printer.com/images/BBB-eMMC-flasher-debrew-v2014-06-2014.08.20.img.xz

The file size should be

125333988

and the md5 sum should be

95720960f462b6f7d3d6bcdadbe0d08d

If you are on a Linux box you can flash the image to a 4GB micro sd card by typing this in a terminal: 

sudo -s 

 xz -dkc BBB-eMMC-flasher-debrew-v2014-06-2014.08.20.img.xz | pv -s 3430m > /dev/sdX 

exit

where sdX is your drive letter. (probably e or f)

Once the flashing process is complete, which should take about five minutes, all the blue leds light up and you can remove the SD card and cycle power.
