I would do away with supports on this and make sure the bottom is setting and centered planer.
then snap to floor if the bottom is planer it will print from the bottom up.

With all the horizontal surface u are going to have issues unless you tilt at an angle or use bunches of supports.

I would do like AK says and make sure the bottom surfaces are planar and just snap to floor with no supports.

In my experience, if you simply snap the model to the floor, you will likely end up missing part of the base.
Since the Core "sinks" the model approx 0.5mm below the floor, I will either (1) put the model on a foundation disk and remove the disk after curing, or (2) extend the model base approx 0.8mm to compensate.

If you snap to floor u will still have to support that area in the middle of your model due to the horizontal surfaces not snapped to the floor.

True what Robert said I overlooked that. I am sorry
So I would attach one support to the side then go back to model mode and then snap to the floor.
Now you can open it up in support mode and the model will stay down and grow from the bottom and you can add supports under the model from the bottom.
BUT Beware!!!! Slice this model now don't move it whatsoever!!

when you go back to model mode DO NOTHING any change you make now will force the model up to the top of the supports and you have to start over so if your going to do several or plan on moving it after this it will move up and you will have to go back and remove all the supports and start over.

I would recommend tilting your model. To understand why, think of the mechanics of what is happening when the first horizontal layers are being printed. The layers are only .03 mm thick. When they lift off the surface, they are not very stiff. When they are pushed back down on the surface, they must displace the resin that has flowed the layer. The fist layer is not fully cured and may be about as stiff as a wet noodle. The lack of stiffness means that not all of the resin will be forced from underneath the thin layer, resulting in a wavy surface. These unsupported layers may look like they are drooping.

Check the slice previewer to see if your have large "red" areas. The red areas are unsupported. I try to keep unsupported areas less than about 1mm or at most 2 mm. In your part, you will see unsupported layers that are more than 5 mm long. These long, thin layers will "float" when the part returns to the tray.

I would add all my supports in CAD then import and snap to floor or tilt like suggested.

I have all the solutions that you have suggested and tried but the result did not change. To improve the output quality of the device, should settings be made within the device? is it possible to carry the machine from the airport to the workshop Malfunctioning device settings?

To check your machine do the test print.

This image is for b9 software. How the waves created on the object can be deleted؟Because these waves appear on the output of the machine.

I think the only way that is possible is if the file u are converting to stl has the waves or the stl has the waves.

Post the file of the ring in .3dm if u have it.

I opened this in Rhino and I don't see it as a problem.

Is this how it came out when you printed it or is this just what it looks like in
the slicing software?
It may be your software mesh settings are set too low so it shows it rough like that
just print it and see how it turns out.
Post pics of the printed ring.

I just opened this in Matrix and i see
there are 7 models in one for each ring that are grouped ungroup and you will see there are 6 (2 of each) 750 on the inside.
when I use my matrix 8 mesh tool it makes it all mesh as one, but your mesh is still 7 meshes.
do you have a mesh tool or are you just using mesh and exporting it.
that might be why your seeing the lines.
When I click on the rings it shows 7 of them sitting there while there are only 1 each of the supports.
You will also notice my light blue mesh is totally different surface than your meshes.
What are your mesh settings in your mesh tool? that makes a difference too

I just using mesh and exporting it. What settings should I do for the mesh? What software should I use and what is the right method for converting to mesh? This is the image of the ring after printing, the waves and lines clearly visible on it, the difference between the blue mesh and Is there a grid to fix this problem?
To convert to my mesh, I first use the command mesh repair in the matrix, then export the mesh, and then save it as a stl file, and finally confirm the two windows shown in the image. I sent the ringer's image after printing and the process of turning into a mesh and ring file before printing and I hope you guide me.
