In fact, most people seem to have the opposite problem! "My machine seems to judder its way round a cut and the whole machine keeps shaking." The answer is to allow this kind of corner-rounding although how you do so depends on your control software. There is usually a "tolerance" setting as well which affects just how much error you will allow - absolute accuracy means full stop-start but is seldom needed. How much tolerance you allow is very machine- and case-dependent, though!
