I would recommend the bigger driver with the 220Ncm motor - and a higher supply voltage. You will get as much power out of the 180Ncm motor with the smaller driver because it needs a lower voltage.

I'm not sure how EMC expects to get the quadrature inputs, but at least it would need a second parallel port, since most of the pins on the first parallel port are needed for the motors and other controls such as spindle and the like. > Any hints and tips much appreciated. http://home.lsces.co.uk/ModelEngineersDigitalWorkshop/wiki/index.php?page=BreakoutBoard > The PSU is no problemo. -- Lester Caine - G8HFL ----------------------------- Contact - http://home.lsces.co.uk/lsces/wiki/?page=contact L.S.Caine Electronic Services - http://home.lsces.co.uk MEDW - http://home.lsces.co.uk/ModelEngineersDigitalWorkshop/ Firebird - http://www.firebirdsql.org/index.php ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
