Modifying Prusa i3 for syringe pump (no replies)

I'm trying to build a 3D Printer that will print a self curing silk/glycerol solution for scaffolding purposes. So i figured i'd try to build a Prusa i3 and replace the extruding device with a syringe pump (most likely following this design--->[www.appropedia.org]) but I'm not sure how to to do the circuitry or what to change in the arduino code. Im using Arduino Megan and RAMPS 1.4 with drivers.

-How would i connect the syringe pump motor to the RAMPS?
-im using the Marlin Firmware-how can i adjust the coding for no thermal components but just the syringe pump?
-is there any open source coding out there for a similar design?

Would really appreciate some help
thanks
