No, this is not necessary - this projector has "square" pixels (not "rhombuses"). It’s just that the cameras are higher than the projector, that's why we get such a picture (although with the ball mounts shown in the photo, they can be set so that the lines show more evenly). In the new version, the vertical angle of rotation of the cameras is fixed (they can be set closer to each other, or further and also tilted relative to the horizontal axis).
In the photo - an option with two more old "red" cameras "YW500U3 Camera"

Here is a small comparison of the scan of a wax model milled on a CNC machine made earlier by the YW500U3 Camera and the scan obtained with the SUA630M (both scans were made in full resolution, available for cameras - 5MP and 6.3MP, respectively)

That seems to be a good improvement. The photo of the subject is too small to see much fine detail. It looks like there are still some vertical surface lines in scan. When you fuse the mesh, how much smoothing do you apply?

I almost always use these values:
Resolution - 1500
Sharpness - 2

On this camera (due to less noise), the pixels of the projector become more noticeable than with older cameras (perhaps due to the lack of a Bayer filter). And if I slightly reduce the sharpness of the projection - the overall quality and detail are greatly reduced. In addition - this type of scan - this is closer to macro photography. At longer distances, this effect is manifested much less.
P.S. In the future, I would like to try scanning with another projector that has FullHD resolution.

Decorative frame around gearshift cover. The top and bottom were made in different scans - they did not combine with each other.
Scanning was done with a Custom user preference - 23 patterns, only vertical ones - on average, about 9-11 sec per scan with one camera.

The first "full" scan made using two MindVision SUA630M-T cameras.
Scanning, to increase accuracy, was carried out in composite (not advanced) mode, because with full resolution of the cameras, the RMS on my tables reaches 1.05! However, this did not prevent the scans from forming into a single unit in the automatic mode (horizontal turns).

Also a link to the received stl (if anyone wants to see / twist the received scan). The size of the scan in archived form is about 30Mb

Excellent detail! Really nice. What calibration scale?

Here the other day I scanned a D4.5mm drill (dual camera "composite" (not advanced) mode) .:
Drill bit D4.5mm
Drill bit D4.5mm
No additional frosting. The drill was almost new, oiled; after drilling, sticky pieces of chips remained.
Here you can download the resulting STL model.

A 50mm calibration chart was also used.

Is that scanned with a coating spray, or uncoated?
