After playing around with some KDE distros recently, I came across an article saying that Fedora was going to incorporate 3d printing software. I then remembered that I had been using Korora Linux about a year and a half ago. I downloaded it to see what it offered and was pleasantly surprised.
Whilst there were some minor issues with updating using the Apper program, it was an upstream issue that has been reported and is being worked on I used YUMex instead.
I installed Pronterface and Slic3r and it was really easy. Simple as installing from YUM. In Pronterface I clicked connect but it did not connect. I realized it was a permissions issue. I did a quick check and found that to fix it I needed to add myself to the tty group. That was all the installation configuring needed.
As for other choices, the repositories have several other 3d printer utilities that can be downloaded: skeinforge, Cura, netfabb basic are a few that come to mind.
Overall, I really like Korora KDE edition. I had no issues setting up and running 2 monitors, and I have a spinning cube desktop. Considering the age of the computer it runs pretty well.
While Mageia5 has not quite been released, using Mageia 4 I did have to go and set up Slc3r and Pronterface from GitHub. It took quite a while and it was a lot of reading to figure out if I had all the dependencies. It is mentioned that it is proposed but I am not sure if the drivers will be added to Mageia 5.
I am pretty sure when I do my next full back up and reinstall of my main computer I will be moving from Kubuntu over to Korora.
