Hi Everyone,
     Anyone know for what all reasons a stepper motor can miss steps?  I am
driving a stepper motor using PIC 16c74 and I am moving it by 40 deg.  But
after 16 x 40 deg (i.e after giving 16 , 40 deg rotations), I am missing 40
deg.   How can I position accurately my stepper.  Is it related to the
pulsewidth?

Thanks and regards
rams
