Interesting.
I have the AT102 scales on my lathe, and the head unit I have looks older. Perhaps that's why I have only .001" resolution on the X axis (cross slide) but .0005" resolution on the Z axis (apron/carriage.) It's moving the same amounts, but because it's doubled in X that's probably why it wont display the 1/2 thoudsandth.
The head unit I have seems to have a few features that one doesn't, all related to being able to use it on a lathe for the option of incremental (depth per side) or diametral (on diameter) readings for X or Z.
Having the 1/2 thousandth readout for a mill isn't overkill. I have it on my Alliant/Prototrak. I wish I had finer, down to 0.0001" increments.
