cube without top gets a top face added without my input.

Hello!

I made a plain in blender i added mods to it to make a box shape object,  when i bring it to the software i can see the shape has no upper face, i slice it and on the preview it shows a top face being made, how do i stop it?, all the modifiers on blender have been applied, there are only real faces to print., why does it add a top face, the bottom face is at the bottom, there should be nothing to print except the walls after the bottom is printed, yet it adds one out its own imagination.

It sounds like you didn't create a solid in blender.  Blender lets you create infinitely thin walls - which are not printable (well they are printable as infinitely thin means nothing is there).

 

You need to specify the width of your walls in blender  by creating more surfaces.

 

Alternatively you can set infill% to zero and top thickness also to zero since you are just printing a simple cube.

 

Maybe you should show what the part looks like in blender or in preview mode to verify what I'm saying. There are other possibilities.
