Re: [CAD_CAM_EDM_DRO] Re: Power Supply for Gecko 320 and servo motors for 3 axis router

I've been running my Z axis servo motor with a Gecko G340 with a Lambda
switcher for a couple of years now. It was going to be just temporary when I
installed it, but since it has worked flawlessly so far, I never got around
to changing it out. I am not using any external capacators on it.
