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.
I need to make a troubleshooting guide for this, but until then. Can you measure the resistance of the coils at the solder points to the board or the screw terminals? Does the light on the arduino turn on when you plug power into it? If so, does the light on the MOSFET module turn on shortly after? If so, try measuring the current at the 12v in on the MOSFET before and after the light turns on.
