After finding a solution for the bluetooth problems i have exactly the same problem.
Calibration do not fix it. Are the lights (see picture from SHY) the problem ?

Same problem here. When I use feature scan mode it never manages to produce a perfect 360 Scan without overlapping ends, not even with the small bust included in the package.
With some objects, that do not have many small features, like the included bust, the software manages to produce a usable result after fusing and meshing, most of the time, but objects with small features can only be scanned when I increase the marker density on the turntable by adding marker stickers to it and use marker mode for scanning. The output is still not good and needs a lot of manual postprocessing. Feature mode never produces data that can be correctly fused by the software in this case.

The lights are little too bright to be used with MINI in general especially if you use cold colored LED, but the bursting of the frames while scanning is another issue not related to it .
I see lately many users have this problem , for some the calibration fixed the issue , for others don’t .
So I am thinking what can cause it , the device ? Since I can’t recreate any of it using any of my devices with the same program build and I had upgraded the firmware on them all as well.
On top of that the DATT do not helping here while scanning and trigger the issue even more because of the accumulated frames that the scanner captures while changing the position and not rotating while doing so .
@Revopoint3D-Gena said it is the software when it is open in full screen , but I can’t recreate any of that issue or any of my friends either.
A software bug would affect everyone… but it seems affecting mostly users with the last batch of MINIs devices .
So if you ask me , I would point point my finger on some of the new devices and it’s driver/firmware as source of this issue .
And the issue I talk about is the one showing in the video when the frame bursting at once while scanning of the bust .
That is completely something else than mandala effect or losing tracking due to lack of features .
You see half of what you are saying is the opposite of the rest what you are saying .
This type of scanner needs a lot of features to be scanned easier, reduced features make it less easy to scan .
Marker mode do not cares about your objects features, it only cares about the markers as that is the tracking point in this mode regardless of what are you scanning as long most of the markers are visible in the depth cam preview ( or glowing red while scanning )
Feature mode uses the object’s features as marker points, so how many extra features how better the tracking result .
It scans object with less features more difficult.
When you scanning partial scans for merging , you need to edit them before merge , clean the most parts that would overlap too much both of the scans while merging focusing mostly on the merging edges on both scans .
If you use just fused point cloud for merging there is a postprocessing workflow that you need to follow, clean the scan from overlapped points, lose points etc …
To make your work easier just mesh the fused point cloud after scanning in Revo Scan without using denoiser or closing the holes , it will do better cleaning job than manually in Revo Studio , then use the 2 meshed scans for merging . You will have less headache while cleaning and better merging results in Revo Studio .
This is the solution for the messy point cloud the software produces at this moment that are not as much usable outside Revo Scan if not meshed before .
You can check also my video to see the workflow .

Maybe I didn’t express my promblem correctly, I’m not a native english speker.
What I wanted to say is that I’m not able to get a perfect 360 degree scan without at least a non fitting overlap at the seam when I use feature mode, regardless if how detailed the object is… but if the object has less detail, e.g. the included bust, the RevoScan and the RevoStudio fusing does a better job and often delivers a perfect result, while this is not the case with more detailed objects where fusing leaves a lot of artefacts which cannot be removed using only RevoScan or RevoStudio.
I know that marker mode only uses markers, but in cases where I have a small detailed object, marker mode with manually increased marker density on the turntable gives me a better scan and less unwanted overlap and thus less artefacts than feature mode. I will still have to do a lot of manual cleaning in MeshLab and Blender, though, but sometimes this is my only way to get anything usable out of the scan.
I understand your problem , that happens when the scan area was overlapped too much with multiple frames and the point cloud fusing option did not cleaned it or fused it correctly, what happens often .
Try to capture at maximum 300-320 frames per one 360 degree rotation and see if it helps you with the results and if not please post the screenshot result as it will help in addressing the issue .
And if you use DATT via Revo Scan you going to have issue regardless what you trying as that is not the proper way to scan objects the way it was made . But the R&D team working on improvement.

You could try with one of the other options for controlling the DATT remotely
like this one I have done for Android, at the moment it doesn’t work with Android 12 & above but I’m working on that, it may eliminate some of the problem or prove if it’s linked to the DATT control through the software or something else

and if you use Android @shyblower , follow the link Johnathan just posted for the APP to DATT controller that will give you better results until Revopoint come with better solution .

I restarted the machine and computer multiple times, same problem.
Tried turning off the lights or changing directions, still the same problem.
Every time I move the size and position of the light or decide whether to turn it on or not.
If the exposure is overexposed, the lower left corner of the software window will display red. But I adjusted on the video, no red display
I purchased a POP2 scanner.
MINI Scan+ with the portable turntable, there is no such problem.
When this problem occurs, restarting the computer and machine does not help. The Bluetooth devices recorded on the computer and software must be “deleted” and the connection searched again.
But even after doing this, there is still a delay issue after using DUAL-AXIS TURNTABLE again after 2 turns
Thanks for your reply, I love your articles and videos. you are my teacher!
I use IOS (APPLE), but unfortunately I can’t use this APP, I can only wait for the software to update

Hi @SHY I do experience delay with the DATT when using via MINI/Revo Scan , long delay after I push the button , I don’t have any other BLE device connected at that time as my Bluetooth is actually closed , I use it via MINI Bluetooth.
I don’t have issues with delay using DATT via Android APP , it’s response is quick and instant .
After downloading the latest Revo Scan for Windows 4.1.1 and trying the very confusing manual function of DATT in Revo Scan I just giving up on using it via Revo Scan , it don’t works proper for my liking.
Good hardware but the way it is running will not improve any scanning here when using via Revo Scan .
They should create a separate phone apps for both systems , as right now it delivering the best results so far.

how is possible to set 300 frames every 360 degrees? that stupid DATT doesn’t turns fast than 1" per degree and so in every complete turn it will capture more than 300 frames
You can’t since DATT captures at max speed 360 frames per one rotation .
Many of us have a regular turntables or turntables with speed regulation .
Actually the DATT speed is 35.6 per one 360 degrees rotation and no way to speed it up .
However 300-360 frames per one rotation is acceptable .
Use the manual function the latest software offers for better results and start scanning at Tilt angle first , avoid scanning while the object is not in movement .
I’m using DATT with Android app, but rot every rotation it scans 600 FPS, not 360
MINI can scan 10 frames per second using DATT at fastest speed 10x36= 360 frames no matter using it via Android or Revo Scan.
One rotation, not a full scanning cycle.
The fastest speed of DATT is 36 seconds per one 360 degrees rotation .
600 frames is 10x60 sec per rotation ( DATT speed at 60spr ) means it took 1 minute to turn the object 360 degrees what is too slow even for POP2 in color scanning .

So maybe my datt doesn’t work well, as my mini, because I’ve tried in every way and I didn’t get a decent scan. I sprayed, changed angle, waste a lot of time and I just frustrated myself
This Object is 50x38 mm. It’s not able to capture details
This is actually a relief, so you have to scan it at zero degree tilt with DATT exactly 10 cm from MINI to a center.
I scanned smaller relief than this but it is tricky to get the proper angle to capture the fine details .
Best way would be to use the DATT controller app with DATT , and scan only 180 degree angle in place of 360 adding the back later in Revo Studio as I assume the back is flat right ?
Fuse it at 0.02mm and Mesh at 6
You can also try to lay down the eagle flat on the turntable and keep the MINI almost above it at 10cm distance from the center and run 360 rotation cycle .

The back is not flat but it doesn’t matter, I was testing Mini’s skill but I’m not satisfied…
I have also tried a skull ring but it also gives me bad resulsts
Put your eagle on a black plastic , keep the distance at 10cm from MINI and handheld scan it , you should capture each detail of your sculpture without issue .
Scanning rings require some practice and merge of multiple objects and one of the rather difficult tasks .
