Re: [CAD_CAM_EDM_DRO] Gecko Drives with 8A motors

Hi Tim,

Yes! The resistor was meant to be "current set" resistor for the G210.
I note that it's "open" for 7A. Me, I'm down around 2A!

Much better to use a little 1/10 W. resistor then a 10W (or more) L/R
resistor! I LOVE these Gecko's!

Now all bill needs is an "open" resistor! ;>)
