It doesn't look like I mentioned it earlier in this thread (or I missed it in a quick review), but when I used the turns counter together with the DRO to measure lathe travel to verify some gear ratios they came out wrong. I sent some data to Precision Matthews, and they instantly suggested counting the teeth on the 90 tooth gear. I did so (using a photograph printed on a sheet of paper) and sure enough there was an extra tooth on that gear marked Z90. They have seen this on a few lathes, a mismarked gear. They had just run out of that gear at the time (May) and I've just now received the replacement (and verified the tooth count). Good service. Something to be aware of, easy enough to check with a caliper or DRO on your lathe.
