Build a distance sensor for use on t-slot channel.
Put a tape measure along the slot in a t-slot channel. Use a linear image sensor to look at the lines on the edge of the tape measure. A 3D printed carriage could keep the sensor aligned on the t-slot channel. The 3D printed carriage could be generic or custom designed for each application.
The Toshiba TCD1304 sensor might work. There are about 3000 pixels per inch, so a movement of 0.001 inch would move the image 3 pixels.
Later, a custom tape could be built that uses Gray codes to embed the absolute location onto the tape itself.
