Regular/Maximum Fan Speed Threshold

Recommended Posts

When I load any STL model, I get the error message shown below: "Unable to Slice with the current settings.  The following settings have errors: Regular/Maximum Fan Speed Threshold".


This occurs with the "recommended" settings as well as my custom settings.


OpenSUSE Leap 42.2

I have tried already tried a variety of settings, but no luck.  Can you suggest a trial set of settings related to fan?


I need to clarify:  Cura slices fine with the provided profiles (that are not compatible with my printer).  I found a similar bug report on Cura 2.4 at https://github.com/Ultimaker/Cura/issues/1417

In that case, the error identified was not the actual error.  I tried the "fix" to that bug, which was to export and then import the profile, but that didn't help in my case.

I might also mention that these models all work fine with 14.12 ( my Cura version before trying 3.1).

    • "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.
