Machine Vision coupled with an array of jets, only actuating those required, might be the way to go. When a pocket is identified it is presumably a known time delay until that pocket is under a calculable jet position. The same approach might work with a movable single jet, but that might not work if more than one pocket can be in a line across the conveyor. Interfacing to LinuxCNC shouldn't be too hard, either pass movement commands to motion from Python, or ignore motion altogether and pass locations to a Limit3 comp which drives a stepgen / PID in a HAL-only config. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
