For those of you running your printers from a Linux PC, what slicer software works for you? I switched from Windows to Kubuntu about 6 weeks ago. Had been using Orca for about 2 years, but the Linux version doesn't fully function for me. The build plate preview and functions are just a blank page. Trying to link a 3d printer causes Orca to crash. From comments online, there are plenty of people with the same issue and no resolution yet, using various Linux distros. So is anyone having luck with a slicer program using Linux, Wayland, and a nvidia graphics card?

Update 07Aug25: so far seen that Orca does not work with the latest versions of Kubuntu (25.04) nor Ubuntu (25.04). That's trying both flatpack and app image. Installed Mint Cinnamon 22.1 (based off Ubuntu 24.04), and Orca partly runs from a flatpack install. The build plate image and features do show up rather than a blank page, which is a start. Unfortunately trying to link my printer by IP address causes the software to crash after I click on the Device tab. Now Orca won't reopen without immediately freezing up, then crashing after about 20 seconds. I think I read about a workaround on Discord for this, need to find that discussion. Downloaded Prusa, just need to try that as well when I can get back to this. Cura refuses to connect to my printer at all so far. It's been revamped to align with Ultimaker printers, changed a lot from when I used it a couple years ago. I don't think it likes my Klipper setup. May work if I went back to stock Creality firmware, but I have no desire to do that.

Update 09AUG25: Right now running the LTS version of Ubuntu (24.04.3) and Orca is usable. Installed using the flatpak. Like under Mint, I can get a visible buildplate and work with a model under the Prepare and Preview tabs. I entered the IP address for the printer under Hostname (using Octo/Klipper for Type since I'm on Klipper) and can upload files to the printer. So long as I don't touch the Device tab in Orca, it doesn't crash or lock up. Access the printer through the web interface, just put the printer IP address into Firefox and can run from there. So, I have something that works at the moment. Thanks everyone for suggestions, it helped point me toward something workable!

Huh, I have not had any issues with orca slicer on Linux Mint at all, I've been using it exclusively for over a year now. Haven't had issues linking my printer via WiFi either, I just put the IP and port and it worked right away.

I don’t run Linux , but I love Prusaslicer and it is available for Linux: https://flathub.org/apps/com.prusa3d.PrusaSlicer

OrcaSlicer has now a Flatpak Version on there Github. I always used Cura but since one year i use Orca

[-] fluxx@lemmy.world 1 points 1 month ago

I use cura on Ubuntu without issues, the appimage version. I did also try prusa/super slicer not too long ago and it worked without issues as well.

I'm using Fedora KDE 42 and I found that to run Orca well I had to switch to the flatpak of the nightly builds. It still crashes sometimes, but not very often.

Bambu Studio was stable, but I have ditched it for Orca. I also use Prusa Slicer to run my Klipperized Mk3s. Prusa Slicer has always been rock solid for me no matter the distro or OS.

I use PrusaSlicer from Flathub. I was using PrusaSlicer on Windows before switching to Linux. I've been using it since the original Slic3r stopped getting updates. Because it's available as a flatpak it should work on pretty much any distro and immutable distros

For what printer ?

[-] EchoCranium@lemmy.zip 1 points 1 month ago

My printer is a Ender 3 S1 Pro, running Klipper/Mainsail on a raspberry pi SBC.

Linux (Mint) and Nvidia GPU here. I use Cura. There is a weird bug where, if you open a file right after the program loads, it will act as if nothing happened (you can open menus, rotate the view etc) for maybe a minute until the model pops up and you can go about your business. Other than that, no issues.

You can disable the USB printing module if you don't use it - that's the one causing this bug. It should be fixed in the next release.

[-] papalonian@lemmy.world 1 points 1 month ago

Interesting! Thanks for the info

[-] DavidP@lemmy.world 0 points 1 month ago

Yep, I'm on Mint too and just live with that bug.

[-] papalonian@lemmy.world 1 points 1 month ago

Someone else replied with a fix! Haven't tried it myself yet.
