Re: [CAD_CAM_EDM_DRO] Gecko 2xx "Nema 42 modification"???

Nice work, Peter. I'm very impressed with the quality of construction. Is
the transformer one of those 86vct, 20A Banner Magnetic beasties? What DC
voltage are you applying to the Geckos? What's the cabling you use to the
motors (size, shielding)? Nice looking connectors on the panel and at the
motors. Expensive? Oh, and can you share some of the specs for your big
motors for comparison? Questions, questions, questions ;-)

Cheers!
