Hi,
It's a nice project! I see the use and the more dynamic feedback we can get from 3D printers the better.
I find that even after bed leveling, the distance to the nozzle is not uniform and changes rapidly with time.
Therefore ideally you would want to measure the distances across the entire bed before a print and use this height map to feed into the gcode so that at every point, the nozzle will print at exactly the same print height. If that is possible I will consider buying one because it will drastically improve my prints, especially large ones.
I know the person responsible for 3D printing at the Eindhoven university: https://www.tue.nl/en/university/dep...-uid/20070339/ I think they will be interested.
