Can someone give me a brief intro to orca slicer? Who is it made by and what's it's quirk?

For example prusa slicer, made by prusa, prioritizes user interface and has powerful almost modeling features (text, cutting etc)

[–] [email protected] 19 points 11 months ago (1 children)

You're four forks deep now Slic3r to Prusa Slicer to Bamboo's slicer to Orca. It also borrowed a lot of ideas from Super Slicer. Since it's open source, and has been gaining some momentum, it seems to have a decent amount of contributors

Why Orca?

all the features you know and love from things up the tree
a revamped UI
built in tuning tests (temp tower, extrusion multiplier, volumetric flow, pressure advance, etc)
great Klipper integration if that's your jam

Did OrcaSlicer ever bring back the option to slice automatically when changing settings? It's called "Background processing" in PrusaSlicer.

I used to slicer hop around, then i discovered orca. Just the best imho

Edit: its an open source fork of bamboo slicer

[–] [email protected] 4 points 11 months ago* (last edited 11 months ago) (1 children)

And Bambu Studio is a fork of PrusaSlicer

[–] [email protected] 5 points 11 months ago

Which is a fork of Slic3r

Orca slicer is a fork of Prusaslicer

[–] [email protected] 7 points 11 months ago* (last edited 11 months ago) (2 children)

And it's fantastic!

Edit: its actually a fork of bamboo slicer which is a fork of prusa slicer

[–] [email protected] 4 points 11 months ago (1 children)

Fork of a fork of a fork.

The beauty of open source software

[–] [email protected] 1 points 11 months ago* (last edited 11 months ago) (1 children)

What are the advantages over Prusa?

Ease of use or features? Both?

[–] [email protected] 2 points 11 months ago

I'd say all of the above. Its integration with Kipper is also very good

[–] [email protected] 3 points 11 months ago

It's worth giving a try

[–] [email protected] 3 points 11 months ago (1 children)

Does it work on recent Linux releases yet?

Appimage doesn't start because it relies on a system package that does exist anymore, dialogs with grey text on grey backgrounds in dark mode, stl repair not included...

Flatpak is in the works but honestly and hope that helps bit I get better prints out of prusaslicer for some reason so not holding my breath or anything.

Ubuntu but it also affects fedora https://github.com/SoftFever/OrcaSlicer/issues/185

The image just isn't being built correctly which is more a problem with appimages but the fact it's still broken... Linux is clearly a neglected platform for them.

All the problems I listed have bug reports just nothings happening to fix them.

[–] [email protected] 1 points 11 months ago* (last edited 11 months ago) (1 children)

I run it on Nobara and Fedora, and I only have occasional graphic glitches with the windows

[–] [email protected] 1 points 11 months ago (1 children)

That's good. I assume you've got the old libwebkit installed somehow. There are a dozen reports around this though so it's a pretty real problem. https://github.com/SoftFever/OrcaSlicer/issues?q=libwebkit2gtk-4.0.so.37

[–] [email protected] 1 points 11 months ago (1 children)

Well I have chromium installed, I use it to segregate Google services to a dedicated browser

[–] [email protected] 1 points 11 months ago

Libwebkit isn't actually chromium, it uses blink which is a fork of part of webkit. Understandable confusion though because webkit was part of kde, forked by safari, and then used by through chrome variants for a long time.

The rest of this comment is going to necessarily be nerdy Linux internals. sorry.

Unfortunately, I'm pretty sure chromium includes it inside it's binary and does provide or use any webkit libraries.

Orca uses it internally for it's browser so it won't start unless it has access to the library. When you build a Linux app it includes the name of the library which includes the ABI (basically the version). Newer Linux release include a different version.

You can see how that specific library stops appearing in Ubuntu releases https://packages.ubuntu.com/search?keywords=libwebkit2gtk-4.0-37

The new version is 6.0 I believe.

Appimage is one of the ways you get around this distro problem by including the versions of libraries. That's why they're so big. There are problems with that like how big the apps are stale bundled libraries with security issues but I digress.

Orca hasn't bundled webkit in the appimage and because of another problem/feature of appimage it falls back on the os library. Since new distros have dropped the older obsolete library version orca can't start.

That's a lot but I hope it explains the problem better.

I would like to help but my personal computer doesn't currently have enough memory to compile orca so back to just watching warning people it's a coming problem for them too.

Any plans to add belt printer support?

[–] [email protected] 2 points 11 months ago

There's a request made here. Haven't seen devs reply yet though.
