MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
The adapter we're using is 12V 1A. The Arduino Nano's Vin can handle 12V in. We were powering the Arduino via a USB because we were still working on the code, but it is now powered by 12V and seems to be ok.
We'll post up a diagram of the wiring soon.
