Re: [CAD_CAM_EDM_DRO] Re: Power supply for Servos - Energy dump and such

Ah-Ha that explains why the power dump circuit that I made from Mariss's
schematic didn't work. I didn't have time to go back and try to figure out
what was wrong but that would certainly explain it.
Can you provide a link to the message number that explains the details?
