Re: [CAD_CAM_EDM_DRO] Liners Encoders and such....

All the talk of linear encoders has wandered all over the map.

Several years ago there was a thread like this in the metalworking
newsgroup.

At the time some people were talking about "Induction" (If I recall)
sensors based on very close precision bearing balls.

They were simply packed tightly in a non-magnetic tube of a slightly
larger diameter.

This seems like the best option from several standpoints including
toughness. Obviously it is more compled to read, but once you make
the step to a uController, it should simplify the task greatly.
