Cura is SO poor at arranging object

Recommended Posts

If you have 4 simple object on a plate, Cura cannot arrange them, although there is plenty of room on the bed. But Cura can show a lot of messages that it can't arrange them, that you have to click to get rid of. DO any of the Cura developers / product owners ever use Cura and an Ultimaker? I wonder

That’s a um3 print area. The dark grey areas are no-print areas. The switch mechanism, bed clips, or if you use dual all that + prime tower


oh nvm you mean the warning msgs. Yeah, annoying thing when many pop. You can disable some auto arrange options on the preferences to remove that ones

This is because auto-arranging is a pretty damn hard problem for a computer. Humans are pretty good at it, which is why most people seem to think that it's easy. Getting the automatic system to the same level as a human would probably take months (if not years) of development.


Cura right now uses a rather naive aproach; It tries to put the largest object in the middle first and then add the other objects. In case of a number of objects that share almost the same size, this is a pretty horrible way of doing it. But if you have a number of models with different sizes, it gets a whole lot better.


The current implementation isn't the best, but it's already quite a lot better than the "old" way of doing it, which was just adding the model to the right of the existing model.

      We're not only trying to always make Ultimaker Cura better with the usual new features and improvements we build, but we're also trying to make it more pleasant to operate. The interface was the focus for the upcoming release, from which we would already like to present you the first glance.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
