Probing a part with a dull stylus gave me false zero readings for 2 days
Ran a batch of 200 flanges in Cleveland last week and kept chasing a 0.003 inch offset that would not go away. Turned out the ruby stylus had a chip on the tip that was barely visible under a loupe, so it touched at a different spot each time. Anyone else run into this and started swapping styluses on a set schedule instead of waiting for obvious wear?

That 0.003 inch is brutal. I had a similar thing with a dial indicator on a mill, the contact point had a flat spot from dropping it once, and it gave me the same headache for a whole weekend. It's funny how we trust the tool until it screws us, then we realize it's the same as everything else in life. Like my car's tire pressure light, it blinks when the sensor battery is dying, not when the tire is actually low, so I ignored it for a month and drove on a flat. We always wait for the big obvious failure instead of swapping parts on a set plan, and then we pay for it in wasted time and parts. You're probably right to start a schedule, I do that with my calipers now, every six months they get new tips whether they look bad or not.
