@droftarts thanks

Hello, i am making a 3d printer and i have a big problem. When i try to move x or y axis from Pronterface motors just buzz and doesnt move(nema 17 with 4988 and ramps 1.4) Z axis works fine. I check with led the wiring and its ok. I switched the motors with z axis and they work, i swichted drivers too and they work. Extruder motor works too. Vref is 0.6v on all drivers.
With this setting #define DEFAULT_AXIS_STEPS_PER_UNIT { 320, 320, 1600, 388.3496 } it only buzzez.
With default #define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 400, 500 } it move a bit but not as it should.
