We would set initial level/placement and then install permanent targets. At a later date we could come back and use a refective "ball" inserted into the targets to see any change. Initial set up was a ***** but later correction was painless.
System cost a hundred grand or better. Just the damn ball was a couple grand.

My system was used on multiple machines in tire building.
An example
There was a building drum that had to be perfectly level. The carcass (bead, liner, ply, apex, sw) was built on that drum. The bead setters were aligned perpendicular to the drum. Tolerance for each was .001". Level and concentric.
Belts, overlay, and tread were built on a separate drum and transferred over the carcass. Same tolerance of .001" at both build and transfer position in all dimensions.
We were always well within those tolerance.
