Yes, it's RAMPS1.4 and A4988 drivers. I have tuned the vrefs to ~0.25V for X, Y and Z. For E i'm using ~0.94V, it was skipping steps with lower vrefs and by calculation this should feed the max amps the stepper can take (not a Cube stepper, mind you).

For the extruder steps, i set it to 147 instead of 80, can't remember the name of the variable (STEPS_PER_UNIT perhaps?)

The controller i'm using is http://reprap.org/wiki/RepRapDiscount_Full_Graphic_Smart_Controller. If you have different controller, you need to comment out #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER from the config and uncomment proper line for your LCD/controller.
