I'll take a look into programming the MCUs before they are soldered. I think there are special holders for that to attach the programmer to the leads. These MCUs are moisture sensitive so I need to check how to handle them after them come out of the pouch with desiccant. Maybe they can be re-dried somehow.

As for calibration, I think I can make the firmware detect the calibration rod (english or metric), because the difference between the 1/16 in. (.157 mm) and say a 3mm rod is large enough to detect from the raw sensor reading. I can get 1/16 in. drill rod with .0003 in. (.008mm) tolerance for pretty cheap ($1 for 1 meter length). Is it possible to get 3 mm drill rod with good accuracy (.01mm)?
