It will handle a higher speed than a full quadrature setup as it only needs to see one edge. I have run it up to 16000 rpm (in the video) with a 50,000ns base thread. The problem with counter-mode is noise rejection, noise is seen as pulses and gets added to the position. (This isn't unique to the missing-tooth index, this is counter-mode in general) -- 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
