Hello, I attached the emc configuration files of my wire foam cutting machine ( http://www.youtube.com/watch?v=PVuPHD1LpL8 ). I don't know if attachments work with emc mailing list.

Just > thinking out loud. I use weight at both ends of a wire to maintain constant force. The weight is inside the plastic tube (if you see the youtube movie of my machine). Both weights can can freely move, that enables extension of the wire when cutting in "four axis mode". > > > > > best regards chris > > > > > ------------------------------------------------------------------------- > This SF.Net email is sponsored by the Moblin Your Move > Developer's challenge > Build the coolest Linux based applications with Moblin SDK > & win great prizes > Grand prize is a trip for two to an Open Source event > anywhere in the world > http://moblin-contest.org/redirect.php?banner_id=100&url=/ > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users
