Re: [CAD_CAM_EDM_DRO] CNC'd drafting machine?

How bout that! I have two of the units you are talking about, one vemco and
one k&e, both are 6ft long. I had
pondered the same thing, they would be very easy to make atachments for.
The problem was how to drive them. I finally decided to try 1/16" aircraft
cable and steppers. I don't know how much stretch to anticipate out of 12'
of cable, we'll see how it works.
