Not only is the error cumulative but is it regular, measure a large number of points all in one direction for as long a distance as possible.
then graph the error v distance you should then see a pattern emerging scale error will be a slope screw error could be a wavy line you can also get a wavy line at a frequency of any gearing device also check what distance one step is on your machine, is it even possible to work to the resolution you want Dave Caroline On Thu, Oct 10, 2013 at 1:44 AM, Chris Reynolds <[email protected]> wrote: > I've been having some accuracy problems and I'll admit I've never fully > understood all of the settings in the .ini file.
