Solidoodle Press Ramps 1.4 Conversion

I got my hands on a used solidoodle press. Upon attempting to print, the y axis was unable to move. I discovered that the y axis stepper motor controller chip on the motherboard was blown. Upon further disasembly I discovered the previous owner had put a screw through the cable. This shorted it out and killed the driver. I am working on converting to ramps 1.4. Im sure I will have many questions to come. Right now, im am wondering what the steps per mm is by default. If anybody can help I would be very thankful.
