i think that before homing machine does not know where it is. machine move to direction of home and after touch home switch it knows where it is. it -- about of moving of machine -- i have simple 3 axis mill - and loaded new emc2 from web today. the point/question is ---- why switches working with emc2 --2.2.4 and these same switches does not working with emc2---2.5.4 ?? how to identify and find that problem? hal meter has many things which file do i need to check to find problem ? maybe i did --- found a bug--- how to prof that?
