I think I would just edit the .ini file, where you will find the plus and minus limits defined in a verse per axis. I have mine defined wide enough that I can zero that axis up against either mechnical limit, and move to the opposite end. Obviously I don't have power enough to damage things when I hit the mech limits, so all I lose is whatever zero I may have set when I hit it & go another few steps on the steppers, so I back it away till its free and zero it, or just locate it on the workpiece and zero it on whatever corner the code expects to be the zero point. This obviously _won't_ work for bigger, capable of damaging itself machinery though. There one really needs to have limit switches and use them. >Paul Stenlund > > >---------------------------------------------------------------------------- >-- _______________________________________________ >Emc-users mailing list >Emc-users@lists.sourceforge.net >https://lists.sourceforge.net/lists/listinfo/emc-users -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
