I apologize if these questions are redundant, but how many "dots per inch" is required for proper z-axis resolution of a general purpose 3-D printer? And assuming our z-axis measuring equipment was capable of measuring in increments that were infinitely small, at what point does the argument become moot because the laser's field of view in our Peachys (or perhaps the behavior of the MakerJuice in relation to the laser that we're using) can't keep up with the performance level? In other words, I guess, what's the lowest resolution that everyone would be okay with?
