Re: gecko wiring help

Bear with me as I am very much electronicaly challenged. I set
everything up in turbocnc as you said I then put the negative and
postive leads of my DVM across the step and dir terminals on the
gecko and show arounf 3.25 volts, when i jog the opposite way it goes
to 0.00 and when i again go the opposite way it goes back to 3.25, is
that what I am looking for? As far as the resistors I am not sure
what to go with. My motor is rated at 2 amps which would be a 18k
reisitor, do I want to go higher/lower than this. Thanks so much
Alan for taking to time to help me along.

Thanks again,
Matt
