I'm trying to set up a ramps 1.4 with A4998 drivers and need to adjust the current limit correctly. Any idea what the correct current limit should be on dobot steppers?

I have found through experimentation that 250 ma (roughly .3 volts on an a4998 with 0.1 ohm sensing resistor) is sufficient current at 12v to move smoothly and rapidly, assuming only a light load on the arm. This keeps the steppers and drivers room temperature cold.
