RE: [CAD_CAM_EDM_DRO] Re: Stepper motor speeds

The vias (feed throughs) are made by soldering a wire on the top and
bottom of the board. All the tracks that attach to components do so on
the bottom side. I didn't think of this on the first rev of the board,
it's kind of hard to solder under a part :-) I was able to make it work
though.

Regards,
JJ
