Re: [CAD_CAM_EDM_DRO] Stepper Power supplies

Andre,

Good news and bad news

The good news is you are looking in the wrong places.
The bad news is - no raise for you.

You do not need a high dollar regulated supply, only the proper
transformer, bridge rectifier, and a capacitor(s) to build yourself a
good unregulated supply. see the gecko website for a paper on ps's

That will get you started, You should be able to put one together
for under $30.00 if you can find the transformer cheap. Look
on ebay, electronic surplus websites, in dumpsters, etc and you will
come up with one.
