The home position was just set at 6" arbitrarily. That's what I said. But then the home position may not be called home position. It might be a workpiece origin, a reference point, what ever. Homing is complicated! Not at all! But wordings and diagrams should be clear and understandable.

Reinhard, I agree that it's logical to use positive offsets for tools in a spindle (since a negative physical size is nonsensical). However, what if you have an auxiliary spindle with a tool tip above the zero height of the main spindle? I'm not saying that's a wise choice, but it would be
