Hi Fred,

Thanks for the comments. I can't afford one either, but did you read
the post from Peter? Not THAT sounds like something we could make! If
we scan like we are cutting cross sections, then I think we'd have
contours to cut. We might be able to generate "scan contours" in
vector, and then the output points would be arranged in contours... I
think.

Getting a switch contact read is not hard, but I have not seen any Gcode
words that would save a data point to a file.

Wouldn't the digital indicator still be a single axis of motion? OK if
you control the approach (rotary table?), but a lot of work. I'll bet a
clock maker could replace the needle of a "Last Word" dial test
indicator with an encoder disk, and then we'd have something similar. I
need a dial test indicator first!
