scans are bad with both lasers

Just because the lasers cross each other in the middle of the turntable, it doesn't mean they're calibrated. 

There are quite a few variables at play.  The laser lines must be perfectly vertical , the camera must be vertical (no tilt), the elevation of the horizontal cross-hair in the camera view must align correctly with the calibration tool, the vertical cross-hair and the and the lasers must line up with the vertical line in the calibration tool, etc.

Do a search on this forum for calibration and you'll get more detailed information on how to do The problem you describe is exactly as expected out of misaligned lasers and camera, as well as possible incorrect input values in the setup page.

If I understand your question correctly, you're asking if the camera is slightly off center would it cause problems.

First, if the camera is off-center with respect to the turn table (and centerline of the scanner), it's no big deal, simply turn it slightly to point it back to the center of the turntable. 

If the camera is offset slightly, and is no longer in the middle of the 2 lasers, all you need to do is measure the distance of each laser from the center of the camera and input that number into the setup page in the right and left "Laser X" box.  Don't forget to use a negative number for the left laser value.

Because of variance in prints and builds, the odds that the camera is perfectly centered between the 2 lasers are pretty small.  That is why you can enter separate values for right and left.

AS for the issues you're seeing in your scans, I have no idea.  It could be anything.  You didn't post any photos of this so I don't know what they are.  They're probably reflections and noise.

It tried scanning small cars and such (like hot wheels), and frankly they weren't very good scans, more like meh.

So I measured the length from the camera lens to the center of the laser, and the distance was about 5.25 inches which is different than the 4.95 that is originally there when you first download. I do believe that is the problem with why my scans show two images of an object when I use both lasers for a scan.

However when I try to change the values in the setup page to 5.25 and -5.25 and click save, it gives me an "ERROR invalid laser pin settings." When I go back to the setup page the values are still changed however I don't think the system is applying these changes because there is no difference in the scans compared to before the value was changed. Why are we getting this error and how can we fix it
