The logical way seems to me to have a switch of some sort (mechanical, optical, proximity) which is "on" for all positive angles and "off" for all negative ones. Then the homing sequence would know which direction it has to move to find the edge. Then you have two possible homing sequences: a) if the switch is "on" a fast move to "off" and a slow search to "on" b) if the switch is "off" a fast move to "on" then a fast move to "off" and a slow search to "on" However: I don't think this is type of configuration is currently supported, I think you will tend to get an error along the lines of "home switch set before search move" though it might well be worth an experiment to see if it works. (I don't have a machine here to try it on) -- atp ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
