Short description of error
Before on blender 2.79b we have Duplication Frames and we can uncheck speed button and we can adjust start and end frame.
Here a quick 2.79b stable version.

On blender 2.80 RC3 we don't have instancing frames and group
Here a 2.80 RC3 example of what we need

Dupliframes were removed intentionally, and groups were renamed to collections.

I understand groups are removed to collection.

Is it possible to have Dupliframes because it is impossible to keep the shape of the duplicated object after modifiers array and curve ? Dupliframes allowed him.
Here is a Blender 2.79b example

Is there a solution on 2.80 RC3 ?

You can try one of the community websites and ask how to get similar results:

hint: you could use the BTrace Addon to create a curve from the object motion [using Mesh Follow tool set to Object], then

  • set the curve bevel depth to zero (to only have the curve)
  • convert the curve to mesh
  • instance your stuff on resulting meshes verts

@Brecht Van Lommel (brecht) , @Philipp Kant (philipp) Oeser
Thank you I found a topic of another method https://blender.community/c/actu/bcbbbc/

  1. But with this method the cube does not preserve its scale when I use alt+S on one point of the curve.

  1. I have test BTrace Addon and this is a destructive method because we need to convert the curve to mesh and we can't see the right deformation in real time.

I prefer non dectructive method like DupliFrames in Blender 2.79b.
