There are two different touch-offs: Tool and Coordinate system. On a Mill you typically only touch-off the tool in Z, but each tool can have XYZABCUVW offsets. Lathes will generally use Z and X offsets. The coordinate system offset applies to all tools. So, for a mill with a collet chuck you can choose to touch-off the tool every time, or the coordinate system every time, or some combination. But we warned that unless you are disciplined and know what you want to achieve, using both can get confusing. With a machine that has a "proper" toolholding system then you would touch-off each tool into the tool table, then you can touch-off the coordinate system with any tool and the coordinate system will be correct for all tools. Axis only touches-off one axis at a time. You need to choose the axis with the radio buttons before pressing the touch-off button. Touchy allows you to touch off every coordinate system or tool axis at the same time. I don't know what the other UIs do without testing them as I have little experience with them. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
