The outline of the top pattern inside the base. What the hell is that Prusa Slicer doing?
Can someone explain how to avoid this and why it is still not fixed by the developers?
For example, I am printing a medallion or keychain, which is a disk with some kind of drawing on the surface, let it be Mickey Mouse. The picture is not embedded in the disk, it is strictly positioned on top of it. The disk is set with 100% infill.
By simple logic, the printer should print a flat disk and only then start to form a drawing on its surface. But by some strange logic it starts printing the contours of this drawing in the middle of the disk. First it fills the layer around this drawing, then it fills this drawing. The same story if the disk is not 100% filled.
All would be nothing, but at high speeds, especially at not 100% filling, individual strands at sharp movements begin to rise, the nozzle touches them, the residue of the filament remains on the nozzle, burned and then in the most unpleasant place, by the law of meanness in the last layer, stick into the plastic and spoil the whole model. This is especially true for white color. Customers do not like dirty brown spots on white models.Because of this, I have a constant 7-8% reject rate.
What should I do with this damn slicer so that it doesn't draw a drawing inside the disk?
I know Sweet Cheese's solution, but it is very cumbersome, especially for complex models.
Thanks.

Make it multiple parts. Take your model in Prusa slicer or CAD and cut the object into parts. (You can look up on YouTube how to do this in PS, it's really easy) This will keep the orientation to one another but allow you to apply different properties to each part.
Also the slicer is doing exactly what you tell it, there is nothing wrong with it. Based on the number of bottom and top layers etc. its creating the geometry based on settings you give it
If you want a more detailed analysis upload a zipped 3mf of your file in question and we can look it over.
