modifying Prusa i3 for syringe pump

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

You could use a stepper motor for the syringe pump replacing the one from the plastic extruder. You will need to calibrate the pump accordingly to your needs.

For getting rid of temperature you can set minimum temperature limit to 0.

There are other firmwares that are open source too.
