So, I have to make it work a bit backed off from the work. I got the unit today, and without zooming the image from the camera, I'm not sure I can get .001" or better alignment. But, with zooming in, I'm sure I can do a lot better. I tried it on my 3.5 GHz i5 system with Ubuntu 12.04, and it works very well, with a great update rate. I'm going to have to update the computer on my Bridgeport as it is REALLY old and only has USB 1.1 (maybe even 1.0). I used guvcview, it worked immediately, but doesn't seem to have a zoom function, other than expanding the entire window. Cheese seems to be the same. VLC gives you a 2:1 zoom as the only option. There's a setting for "interactive zoom" but I couldn't see that it did anything. Also, there's about a 3/4 second lag with VLC that I did not see with the other packages. That might be annoying when using it for edge finding.
So, I have to set up a new LinuxCNC computer and then see how well this works with the camview package.
