3MF support in OpenSCAD blocked on 2 package reviews
by Miro Hrončok 05 May '20

05 May '20

Hello. I have started looking into packaging lib3mf to add 3MF format support for OpenSCAD many years ago, but never managed to figure it out. https://github.com/3MFConsortium/lib3mf/issues/8 Finally, with a great help from Danny Hindson, it is ready. There are 2 package reviews: act: https://bugzilla.redhat.com/show_bug.cgi?id=1819148 lib3mf: https://bugzilla.redhat.com/show_bug.cgi?id=1818945 I'd appreciate package reviews from the 3D printing SIG members. Since Danny wants this library on EPEL 7 I have made the specs EPEL 7 compatible. Hence especially the act package is very weird, because following the Go guidelines there was not possible. More experienced Go packager might know better, but it works :/ -- Miro Hrončok -- Phone: +420777974800 IRC: mhroncok

CloudCompare needs new Fedora maintainer(s) for laszip and liblas
by Miro Hrončok 04 Mar '20

04 Mar '20

Hello Fedora 3D printing fans. laszip and liblas are orphaned in Fedora and needed by the cloudcompare package. I'm unfortunately swamped by other tasks and I don't really want to maintain those packages, so if nobody picks them, I will most likely orphan cloudcompare as well. CloudCompare itself could use an update as well. cloudcompare buildrequires laszip-devel, liblas-devel cloudcompare requires liblas.so.3()(64bit) liblas buildrequires laszip-devel liblas requires liblaszip.so.6()(64bit) liblas-devel requires laszip-devel Fortunately laszip has no open bugzillas: https://bugzilla.redhat.com/buglist.cgi?bug_status=NEW&component=laszip&pro… But liblas has some some (segmentation fault, heap-buffer-overflow, illegal address access, memory leak) open for over a year: https://bugzilla.redhat.com/buglist.cgi?bug_status=NEW&component=liblas&pro… Let me know if you'd like to get involved. Thanks, -- Miro Hrončok -- Phone: +420777974800 IRC: mhroncok

Fwd: Lulzbot going out of business and Prusa Slicer updates/bugs
by Miro Hrončok 21 Oct '19

21 Oct '19

-------- Forwarded Message -------- Subject: Lulzbot going out of business and Prusa Slicer updates/bugs Date: Sun, 20 Oct 2019 13:00:01 -0700 From: Mark C. To: mhroncok(a)redhat.com, ... Hello, I'm writing to you because you're listed on the Fedora 3D Printing SIG as TAZ (Lulzbot) and/or Prusa users. First, Lulzbot is going out of business. They've released two updates recently which are not available via the Fedora repos. These are very likely the last cura-lulzbot releases. They contain important printer support and bug fixes. These new releases should be captured (downloaded) and new packages released before Lulzbot shuts down their sites. The source for both releases should be captured in case their last release contains new bugs. Second, an updated version of Prusa Slicer is available. It contains important updates/bug fixes. The current package in the repo is out of date and has a significant bug preventing it from functioning correctly on HiDPI systems. Prusa's appimage based binary does not appear to have the same problem with HiDPI displays. I wrote to Prusa support about the HiDPI display related bug. They stated the problems seen with the Fedora package are caused by "linking against the wrong version of the GTK libraries". Thank you for your time and attention. Mark C.

Any users of skeinforge or sfact? They are both dead upstreams for 5+ years and I'd like to retire them. -- Miro Hrončok -- Phone: +420777974800 IRC: mhroncok

OpenSCAD 2019.05 in F30 updates-testing
by Miro Hrončok 30 May '19

30 May '19

Hey, Fedora 30 OpenSCAD update to 2019.05 needs your karma: https://bodhi.fedoraproject.org/updates/FEDORA-2019-fee53a9610 Note that we also have a build that switches to Qt5 and enables direct printing via OctoPrint, however I'd like to push this update first (instead of obsoleting it). Please, install the new OpenSCAD and report any troubles. Thanks, -- Miro Hrončok -- Phone: +420777974800 IRC: mhroncok

Thank you for the heads up. Tibbs (cc'ed) is already looking into packaging the new version for Fedora in: https://bugzilla.redhat.com/show_bug.cgi?id=1710526 What is the best platform to ask for help if we have problems? Should we reach directly to you via e-mail, open issues on GitHub? (I could probably also meet with you in real life if it helps.) I suppose a major drawback would be lot of bundled 3rd party libraries. I think there might be some confusion about what is "Red Hat Linux", so to clarify, there are two things here: Fedora - tracked above Red Hat Enterprise Linux - never had any Slic3r in it "Red Hat Linux" used to be a thing very long time ago. I'm also CCing the Fedora's 3D printing mailing list for transparency. -- Miro Hrončok -- Phone: +420777974800 IRC: mhroncok

Packaging the new slic3r-prusa3d beta
by Jason L Tibbitts III 27 Mar '19

27 Mar '19

The Prusa3D fork of Slic3r is nearing a big new release (1.42.0) and that stream of development has made it into the beta phase. While they didn't bump the version much from 1.41.3, this new version is significantly different because it jettisons the last of the Perl code and has an updated interface. It also adds support for Prusa's new MSLA printer, the SL1. I have the package building and the end result seems to work relatively well on my F29 system. I've been able to plate and slice some models without difficulty. However, there's plenty of cleanup to do and I haven't dealt with the pile of bundled libraries at all. I do know that the license tag is quite wrong, but I'm pretty sure it's also wrong in the current Fedora release. Also of interest is that the software much prefers to build with wxGTK3 3.1. Of course, we only have 3.0 in Fedora. I think they've renamed the settings directory, and to something different than we were renaming it to. It's probably better to just stick to the upstream naming now even if this means that users may have to reconfigure or rename. The work is visible in my fork: https://src.fedoraproject.org/fork/tibbs/rpms/slic3r-prusa3d - J<
