Re: [CAD_CAM_EDM_DRO] High or Low voltage steppers better for Gecko

Hi Dale,

You saw my setup while you were over to the house. A 2-4 volt motor
would be better (although both of your motors would work), I don't like
the 1 volt because the current must be higher. The 7V would kick up the
20x too high for high performance. I'd also use the Gecko 210's. This
motor keeps the current low, and 37V will run it great. Otherwise, get
some lower power surplus motors for $15 or less each!

232-180-DB 180 oz/in 2A 2.1V $102 from Mendonet are a little more.
Or watch Ebay for motors.
