Newbie, How to touch off Z axis

I think you are misunderstanding my question.

Which cnc machine configuration are you using?

What does it say in the window title bar of EMC2?

What ever you want the present position of the currently selected axis to be... also depends on if you have a tool loaded or not and if your touching off a coordinate system or the tool table.

What do you want to do?

Run what file?

Why is this not possible with 2.4.6?

Because the 5-axis example is not just a simple X, Y, Z A, B configuration, but rather a complex 5-axis kinematics example where the work position and head angles are automatically computed to set the required tool positions and angles relative to the work.

The complex kinematics need to home in "joint mode" before they can switch to coordinated mode.

If you don't need 5-axis machining capability then you can use a simple trivial-kinematics configuration which will start up automatically in XYZ mode.

Have a look at www.youtube.com/ChrisRadek#p/u/10/7WCrqqoZkPg for an example of what is meant by "5 axis" in this context.
