stacker tower will not transport iron or copper scrap. it blocks the belt.

scraps go in all the loose belts and loose storage then gets stuck in the stackers. should work together.

are you suggesting that those are added to the stacker tower? They aren't a dumpable material

None of the scrap variants were ever dumpable.
Not every Loose material is dumpable (e.g. Potatoes or Sulfur).

That's the reason as to why you can't have
vehicles dump such materials even if you wanted to.

And also it's not like dumpable-ility is just a boolean flag,
an entire separate prototype needs to be defined that specifies
additional paremeters, like "pile steepenes" or terrain textures,
which as you might imagine, weren't defined/created for such materials.

See Eryk response above, tower doesn't accept them because they can't be dumped on the ground, same behavior as dump trucks.
