Slow performance in Cura 2.5 and up - once Object is sliced

Recommended Posts

Using Cura versoin >= 2.5 -- I load an object into Cura and while looking at it in normal view - I can rotate / zoom / etc with nice smooth motions. Then I slice it (or it auto slices) and suddenly it acts like i stepped back 3 generations in a processor. The normal view does jumps vs smooth rotation - and sliced view is absurd trying to get to a layer or rotate the image.

This did NOT occur with Cura 2.4 or earlier.

I read that Cura2.5 started using multiple cores - so I restricted my version to a single core - NO change.

Now the magnitude of this is very model dependent. A simple box or such is "just detectable" - but get a complex model with supports and such - and it goes to its knees.

This is very challenging as I really want to stay with Cura and some of the great features being added - but this slicing view issue prevents usability.

Help :-)

    • "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.
