Re: [CAD_CAM_EDM_DRO] Re: MircoStepping Drive Which One?

Ignorance here on voltage/amps for RPM.
What exactly do I need to consider if I am running
bipolar steppers? If I put more voltage to the motor
will that increase the amperage? I assume yes...
but is this linear? 20% more voltage would mean
20% more amerage? Which in turn would up my RPM...
by what? Any rule of thumb here?

Thanks,

Luke
