that the angle camera to projector and calibration panel. I would have a bigger angle than 10 - 12 I use 20 - 30°, I set the camera angle on my camera mount here viewtopic.php?f=7&t=6258 makes it easier to set up :-)

Thanks man !!!!
but is that going to effect the out put of the scan ? or as long as calibration is done we're good to go ?
I also found out the size is a bite off on the out out, I was scanning a square hole , it was a prefect 20cm x 20 cm , but the north-south side output was 2mm less and the east west was prefect do you have any idea ?

try a bigger angle 22°is what David say

go to WIKI and download the manual for sls 2 kit for more info

as I see it a steep angle like 10°will not give best results over a distance but will give better depth to scan.

also check calibration panel is true 90°and panels are perfectly flat.

Hey JDM

Is the number bigger the better ? Or as close as 22 is ideal ?

Thanks

Hi
as it says in the above manual screen shot
tip.jpg


I use 25 to 35 max, guess it depends on what your scanning but 22+ tends to work better for me, if you have more depth to the object 22 should work well if its flatter then 30+ may help,

not really bigger the better tho,
