Re: [CAD_CAM_EDM_DRO] gecko questions

The current setting for the drives will not change with a higher voltage. So
if the current setting was correct before it will be fine now.

80,000 mfd is a way big cap. It will not hurt anything, but you could use a
lot smaller one. There is no real need to get the ripple down to tiny
percentage unless you have a brother in law in the cap business you are
wanting to support. While I do not questions the calculations that Mariss
has in his white paper on cap values, my experience is that you can make a
usable power supply with a whole lot less filtering.
