I installed Cura a couple of weeks ago and it initially worked very well, but at some point it stopped slicing models for me. I can click the "Prepare" button, but after that it just says "Slicing..." and nothing happens no matter how simple the model and long I wait. I've tried resetting all options to default, and even totally uninstalling and re-installing the software, but none of it seems to have made a difference. 

 

I've tried Cura on several different accounts with different permissions and compatibility settings, but the only thing seems to work is running it on a totally different PC.

 

Googling this problem I came across similar problems that seemed to be caused by firewalls, but I've disabled my firewall and this problem is persisting.

 

I have no idea what the problem could be, and Cura came highly recommended so I'd rather not switch to a different software.

 

Can anybody offer a potential solution?

To make sure you're truly back to "zero" with the install, go to Help -> Show Configuration Folder. The folder containing all your personal settings for Cura will open. Close Cura and then remove everything in that folder, once that's done you can restart Cura again. This should have you back to factory defaults so to speak. This usually fixes weird issues.

    • "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.
