That has been noticed here too Jon. So I'll fix that code tomorrow, but I believe I need to figure out a way to certify its accuracy as g2 cut circles seem to have anywhere up to 3 thou, perhaps a bit more of almost random edge wibbles. Difficult when the only dial indicators I have are a 1" travel, .001" scale, and one of the Grizzly .0001" with perhaps a 13 thou range either way from zero. So, how accurate might I expect to see with an ebay optical scale? Good enough to map these screws? Something like this: <http://www.ebay.com/itm/RSF-Heidenhain-Optical-Comparator-Video- Measuring-Machines-Scale-New-in- Box-/201105192906?pt=LH_DefaultDomain_0&hash=item2ed2cdb7ca> For a $150 bill.
