It works OK with a ballscrew. That is with 4:1 belt drive to the nut. For a BP I would guess at 50Nm minimum at the nut for ballscrew, at least twice that for leadscrew. If there is space for the reduction drive then this might not necessarily mean a particularly big servo motor. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
