Prusa and Cura are available on flathub and work fine. AFAIK Orca isn't in the main repo but the flatpak is on their github and works fine for me too.

Orca works just fine on Linux, probably even better than on Windows/macOS, which are a slightly neglected platforms from a dev's perspective.
This is my experience. I do CAD in Windows, but Orcaslicer only works properly in Linux. On Windows, it tends to crash when I tell it to generate gcode for anything but the smallest prints.
Just as well, really. It reminds me to reboot, so I haven’t tried to fix it.
My experience with Orca on Windows is the same. Any complex model causes bedshitting, and I've tried basically all of the solutions suggested on their issue tracker. I had mild success with affinity tweaking (ie forcing the slicer to only use real cores. not hyperthreads) but it's still hitting a ceiling.
At home where I'm running linux, Orca is perfect.
I use Orca Slicer all the time on my Debian machine. Works great!
Can anyone give any advice on either having it work or a Linux alternative with similar functionality?
The neat thing about installing Linux is that there are live versions around. Go to the Linux Mint site and follow their instructions on creating a bootable USB stick. Boot from it and you'll have a working system directly on your computer. You can check if your hardware is compatible and you can also install software there. So if you have some doubts about Orca Slicer, just boot up a Linux and check it yourself on your own machine! It's really that awesome
Orca on Archlinux user here. Its perfect.
What kind of hack-trash distro are you hearing about problems from?
Pick a well supported distro like Fedora or Ubuntu and you're more likely to have less problems with things like that, because if the devs are testing against anything, those will be the distros.
Orca works great on Debian 13 for me (I installed it as a Flatpak)
I prefer Cura and it has native binaries and Flatpak.
PrusaSlicer still works on my 2012 Asus laptop on Ubuntu 22. Use it weekly.
Prusa also works on my nixos 25 machine.
Almost definitely gonna be fine.
I've been using orca on Linux mint for the past two years without any issues. I used prusa slicer before, but I much prefer how settings are managed in orca. Prusa slicer feels like they stopped giving a shit 20 years ago, it feels so horrifyingly ancient to use.
I've had no problems with Orca Slicer. Bambu Labs tries to crash the entire time it is open.
Yeah something is fucky in this release of BBUslicer, it usually opens my file, but will sometimes crash once or twice first. Unfortunately, Bambu P1S so no Orca for me (EndeavourOS / Arch derivative)
SuperSlicer has very good default Voron 2.4 profiles, but it is almost bewildering how many options it has
Orca as a flatpak/AppImage works without any issues here.(Debian 13, Fedora 43) There is also a LinuxServer.io version which I tend to run on my server and simply use a browser.
Basically while I have Orca on my Fedora 43 Desktop and a Debian 13 test machine I got tired of synching the filament profiles and somestimes projects between all family devices (5 Notebooks, 3 Desktops). Therefore we simply have a docker container with the Linuxserver.io Orca. That can be accessed from every device and simply loads models from a NFS share. So filament and process data is unified at this single point.
Additionally it provides an added layer of security as my printers live in their own, fully offline, subnet and only this container,Spoolman/Spoolease and Home Assistant can access it. (Thank you Bambu rolleyes)
I just installed orca yesterday! The appimage mostly worked, but it wouldn't actually slice. I removed that, and found it in AUR, installed that version, and it's been working great. It doesn't support my printer, so I can't print directly, but I can save the stl file and then copy that over to print. I made a small plaque yesterday and printed it, and everything worked fine. (Garuda Linux, Arch derivative).
There is a Flatpak as well which is working really well. I had some issues with the app image in the past
I looked for the flatpak in discover, but didn't find it. I didn't bother looking further than that.
Its not in Flathub. You need to download the Flatpak file from GitHub
Ah, that's why.
With the number of (custom) printers supported by Orca you picked my interest :) What's your printer?
The Anycubic Kobra 3 v2. There might be a plugin or something, I didn't play with it much, but by default it's not in the list. When I picked a close one (the Kobra v2) I pointed it to my printer's IP and it wouldn't connect properly.
Ok. I didn't find anything specific for Kobra 3 v2 (though I didn't spend more than 5 minutes ^^), but I came across this profile for Kobra 3. Maybe you'll get lucky with it... https://www.printables.com/model/982339-anycubic-kobra-3-orca-profile-v2-tested-verified-w
Thanks I'll give that a try
Been using Orca on Debian 12/13 for a while now and it's been smooth sailing
Cura publishes nice Appimages
I'm exclusively on linux, and I'm using PrusaSlicer. It does what I need, and it integrates well with my prusa printer.
I did sniff around, in the name of science, looking at other slicers to see what they offered, but I found no reason to try anything else for now.
Had zero problems with orca.
Both slicers work fine but there are some dpi scaling issues in my experience (both Orca and Prusa) on 4k monitors.
I haven’t printed anything since I made the permanent leap a few months ago. I got Prusa configured the same way from my windows drive in like 5 minutes, including finding and installing it. And I don’t even use a Prusa printer, nor an FDM. It’s literally the goat.
It depends on your distro. I have an AnyCubic printer and have to use their derivative of Orca. It only supports Ubuntu 24.04, so I run it in a VM when I need it. There are some weird GTK things with it too. But still functional.

What printer is that? I also have an anycubic printer, and before I flashed it with klipper it worked just fine with regular plain orca slicer.
Orca slicer works okay, but I have the newer Kobra 3 Max and it doesn't come with the printer profile as of yet. And I still have to use the AnycubicSlicer Next suite to do any remote control. And trying to run it under CachyOS had a lot of visual problems (the Workbench tab shows nothing at all). The command line output is line after line of GTK errors.
By the license, I think they should be obligated to release the source, so if they do that maybe I can help make it less terrible (or at least reverse engineer the remote control protocol).
