The other suggestion people have mentioned is that if the motor is very low
inductance they had accuracy issues. The one user that was plagued by this
solved his problem by running the particular 8 wire motors in series instead
of in parallel. I am running a set of the CMD drives on a Sherline with the
8 wire PowerMax II motors wired in series and it is dead on accurate. I have
not tried the same motor in parallel or half winding to see if it works
better or worse.
