        <title>first build voltages question</title>
        <description> I have in hand a 12V power supply .. arduino mega 2560/ramps 1.4/ 5X A4988 2A stepper driver boards .. 4 NEMA17 steppers motors for my first build.

I was supprised to see that the rated voltage for the stepper motors was only 3.1v 1.7a and I would like to know if this is correct or did I get the wrong steppers.  I don&#039;t want to hook up the electronics before I double check.

Thanks in advance,

            <description><![CDATA[ The voltage rating on steppers is simply the Current  * Resistance of the device, its a fairly useless number<br />
<br />
Steppers are always driven at much higher voltages, 3-4 times or more is quite normal]]></description>
