Re: [CAD_CAM_EDM_DRO] Gecko 201 drive

Hi Ron,

Yes, that's what I had in mind. Although the combination of Mariss'
regulated reference, and a switch would be even more to my liking.
Actually, I wonder if we couldn't use a Dallas Semiconductor
programmable pot (or a similar approach), and allow a default low
current, and a programmable current level from the controller program!
