Retraction is NaN

Recommended Posts

Ultimaker 3

I have some threading problems I'm trying to fix so I am looking at the retraction settings.

Both the speed and distance default retraction settings for all the material profiles shipped with our printer is NaN. Not a Number usually means division by zero or some other numerical problem. What is it supposed to be and is there any way to change it without having to copy the settings into another profile? The edit option is not enabled for any of the profiles shipped.

Which Cura version are you using?

I tried in Cura v2.5 Beta and can change those values (after duplicating the protected profile).

 

Version 2.4.0

I can duplicate and edit the profile but I would like to know what the default value is so I have a good starting point.

And I think that NaN is not a good default value anyway. It's not a best practice in software development to leave something like that improperly initialized.

What printer did you select?

Did you try closing Cura and starting it up again?

Not sure what you mean. I only have one printer to connect to.

As for restarting Cura, this issue is with the default settings of the materials. It always shows NaN.

Ah wait. We noticed this problem a while back (CURA-3037), but it seems only a problem for Windows users and then the bug got lost in a large pile of bugs which we never got around to looking at again :S

OK. Not a big problem since I can set up a new profile. It might explain why some of y prints have such egregious threading issues. It would be helpful to know what the default values should be so I don't have to try 10 prints to get it right.

    • "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.
