Re: [CAD_CAM_EDM_DRO] Re: Re: Stepper power supplies,

Good analogy there Ballendo....especially since I live in a dry areaand some
bunch of greedy idiots want to build a super big development which (if
allowed) is surely going to strain the local water supply....even in normal
years.

I'd pretty much already decidedto go the "plug in" as you need em route
just for the reasons you've mentioned ....especially since the system is
going to be designed to operate at least three (and possibly 4) different
sizes of machines.
