I think you divided revolutions by counts (I recall you saying that encoder resolution didn't matter, but you were using rawcounts, so it most certainly does). So, a 1000:1 error there. (There isn't _room_ in the head for a 7000:1 gear ratio) Also, you keep confusing RPM and Revs Per Second. -- 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, 1916 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
