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.


Thanks spegelius, I got my ramps to work with your marlin Rc..  But I have to ask you something, when I try to move my X axis to the Left going towards the end stop, Pronterface says endstops hit:  X:2.99   The X axis will move to Right no problem, but when I try to move it back to the endstop, it wont let me, is this normal?
Also when I hit Y+ the bed moves forward, but when I try Y- the bed wont go back to the endstop, is this normal??
 Can you tell me does the  X,axis  control the extruder  from left to right?, and the Y controls the print bed going forward and back?,  is this right?
