Manual Motor control problem

I have the Sainsmart kit which includes Ramps 1.4 + A4988 + Mega2560 R3 + LCD 12864 3D Printer Controller Kit and more (http://www.sainsmart.com/3d-printing/ramps-1-4-a4988-mega2560-r3-lcd-12864-3d-printer-controller-kit-for-reprap-1.html).

I have assembled and uploaded the marlin firmware. When i try to manually move the motors via Smart controller the motors move in the correct direction but only move a fixed step no matter whether i select it to move 1mm or 10mm. The extruder motor also moves far too much. Im not sure what i have to change in the firmware as im sure its a problem within the software rather than the hardware.

I have attached my configuration.h file.

Help would be much appreciated thanks.

Did you put three jumper pin caps under each stepper driver board to set your micro-stepping? Sainsmart doesn't ship them with their kits, and without them your micro-stepping is set for 1/1 and not 1/16. They also do not sell the A4988 stepper drivers with any semblance of adjustment on the current adjuster potentiometer, so break out your multimeter and set them to 0.4V if your kit also came with their stepper motors.....

Thanks a lot, i really appreciate the help!
