I think more than two lines might be better. You need to have the right kind of short segments, because on some types, the motion will stop at the end points of of each segment. On the endpoint smoothing types, the computing load may limit feed rates. On the other hand, for machining sharp corners, you want the non-smoothing type of segments. I'm wondering, for this application, if it might be better to build the axis machine, then by hand, push the ball through the desired path and rates while having the computer learn the positions. Then the computer would replay the path to have the axis machine reproduce the recorded motion. This might make it easy to reprogram new choreography on the fly. I don't know how well EMC2 would fit into this. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
