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 used the regular wiring diagram for RAMPS 1.4 with 1 extruder, 1 heatbed (may not be used) and 1 fan (also not required). Second stepper for extruder is not used. Thermistor for second extruder can be used for monitoring, as fail safe or not be attached at all. Connection is described in build manual: http://reprap.org/wiki/ToyREP_Build_Manual
