Arch Linux User Repository

Update on version 2.3.x:

With 2.3.0 being very buggy and no 2.3.1 bugfix release in sight I got main branch building on Arch again and tagged latest commit ( c6b8664c8e276413445ed25d3a8957101143c006 ) as 2.3.1-dev.

Wayland support status:

Please test and report back - a bunch of fixes added, including one for nvidia binary driver performance.

Known issues:

• Camera/Live view/whatever you call it for BambuLab printers doesn't fully work - after a short while framerate drops to about 1fps.

Hi Recently I encounter this package crashing when slicer start (I am using sway and wayland). Uninstalling the font doesn't help. Then I updated to c7814c7 (2.3.1-dev) and rebuild. After long building the new version is also crashing.

For me helped installing AUR/orca-slicer-git. This version is not segfaulting on start. Maybe this info would also help others...

orca-slicer-bin is crashing every time i attempt to open the preferences dialogue / window. ie. ctlr+p. i get a similar stack trace to the one below where it seems related to pango or some font related issue.

i can provide more information upon request if that helps.

@lod ok thank you!

@Delivator the white device tab is an upstream problem that should be fixed. But you need to wait for the 3.1 release or use the git version. As a workaround click the "Connection" button next to your printer and hit the "Test" button. The "Device" tab should now work again.

• no .desktop file and no icons
• certificate error on start
• "Device" tab (in my case a browser for my octoprint instance) doesn't stay logged in and sometimes just goes white and doesn't recover until restarted

@sTiKyt & @Poscat I don't think OP comes back before 2.3.1 release. Like I pointed out before, right now the package is build and packaged "wrong" and against packaging rules. That's also the reason the .desktop file doesn't get generated. You can use the git version for now (this isn't a stable build anyways) or I posted a 2.3.0 build before, with all needed patches backported.

This really needs a .desktop file, for example: (this is what i've been using for orca-slicer-bin, modify it as needed)

❯ cat /usr/share/applications/OrcaSlicer.desktop
[Desktop Entry]
Name=OrcaSlicer
Exec=/opt/orca-slicer/bin/orca-slicer %F %U
Icon=OrcaSlicer
Type=Application
Categories=Utility;
MimeType=model/stl;application/vnd.ms-3mfdocument;application/prs.wavefront-obj;application/x-amf;x-scheme-handler/orcaslicer;

Do you mind adding a .desktop file?

@tflucke I would check that Adwaita font first it segfaults right after trying to access that.

Maybe try uninstalling ttf-harmonyos-sans, if you still have it installed. It led to similar issues in the past.

I installed this update last morning and every time I opened orca-slicer, it would segfault in the middle of the loading screen.

Seems to be an issue related to Freetype2. strace:

I tried with and without themes and neither worked.
