Re: [CAD_CAM_EDM_DRO] Re: POWER SUPPLIES

Because the 1% regulation is based upon a steady load. That is very
different than the load a chopper drive applies. Basically the drive is the
regulator in a stepper setup and you just want to feed it what ever current
it wants. You don't want the supply trying to get in the act also.
