No, these use triangulation rather than time-of-flight which is how they manage such good resolution at small ranges. You could have one mounted rigidly relative to the grinding wheel spindle (behind a cover). Dress the wheel, open the cover, take a reading and have a very accurate measure of wheel diameter to use in offsetting and grinding geometry calcs. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
