Re: [CAD_CAM_EDM_DRO] Making leadscrews more accurate

It's interesting but I think I'd have an awful time trying to shoehorn a cam
and lever into my Dream machine design tho'....especially when it's possible
someone might want a setup using all 3 lead screws for the X axis.

I'm sure it would be possible to mount a full length cam alongside the lead
screws but it would have to be planned for in advance, since you'd also have
to provide some pretty good support for the cam as well.

It's my guess that this system would even work with acme screws as well as
plain old threaded rod. Now THAT (th'd rod) would really bring the cost
down!
