When you have established the diameter press the X button (shown right), enter the value and press the ‘ENT’ key to store the value. From now on the DRO will automatically convert radial movement to display new the diameter on successive cuts. It is advisable to leave a small amount extra on the diameter and re-measure before going for your finishing cut and final diameter for the sake of accuracy.

=== Setting and using the length scale ===

[[File:zeroingy.JPG|thumb|250px|Zeroing the Y axis]]

Face off the front of your Stock and without moving your Saddle Traverse Wheel the use the Y₀ button to the right of the Y-scale to zero it. It's normal convention to regard movement towards the chuck as being in the negative Y direction so your zero point goes on the end of the stock and negative measurements towards the chuck. Then use the method discussed in Turning a Diameter to set the X value.

=== Turning to a shoulder ===

Feed just short of the desired length on successive cuts leaving material for your final shoulder face. Check the diameter when you are close to your finished size. Make your final pass and go to your finished Y dimension to then create your finished shoulder then draw the tool out using the cross slide in order to clean up the shoulder.
