Up really close, like 4 mm from the object, the pixels come out to about .0002" or about .005mm! That is FINE resolution for edge finding, but when shrunk into a little window at native screen resolution or less, you can't see the individual pixels. What I want to do is blow up the very center, maybe 100 x 100 pixels or so to a big, pixellated window. Then, I can move the machine until the edge is right straddling the pixels marked by the crosshairs. This ought to be totally basic digital image stuff, I can't believe these functions aren't already there. Anyway, the problem with what I installed is that the util.crop function seems to be missing. This is what F1oat used to accomplish the zoom. (I guess you crop the image down to a smaller size, then the remaining pixels are expanded to fill the window - voila, zoom)
