Re: [CAD_CAM_EDM_DRO] Re: Dan Mauch DRO board

Hi,

I remember some time ago doing some calculations on this very subject and,
given the size and number of lines on this wheel, without some sort of
multiplier system it is just as well to use the 360 line linear scale. Can't
find the beer mat I did it on though.
