Am I understanding your proposal correctly that 12.3456 is the initial entry in the touch-off dialog because 12.3456 is the current value of the selected axis? If that's what you're proposing, then I sure can see how that makes it easier to do your differential math. However it also has the effect that the default action of touch off is to make no change (hit End, dialog appears, hit Enter, coordinate does not change). Currently, this default action, when no change is made, is to set the new axis value to zero. I must say that most often what I do with touch off is to accept the default zero value because I want to set the system origin where the tool is. I also frequently type +/- an edge finder or probe tip radius. In some cases, though, like for lathe X, I am always touching off the tool and very rarely would want the zero value there. The value I type will always be what my micrometer says (or that number followed by /2 if the gcode is in radius mode). But for lathe Z I would usually want the zero. I think current value and zero are the two initial values that make the most sense, but I don't know which one is useful MORE of the time. I suspect this is a matter of opinion and/or practice and opinion will be split. If someone sees a pattern that AXIS can use to get this right, or a clean, simple, discoverable and keyboardable way to make the user interface handle both cases, please speak up.
