Non-AVX SnOrca AppImage for Linux

Software Snapmaker Orca
1

I have a build script for SnOrca that creates a working non-AVX AppImage for Linux users. I have a similar script for Orca Slicer as well.

Message me for the script or the AppImage. If there is interest, I will put the scripts on my GitHub or make the AppImage available for temporary download. You can try it and YMMV. Honestly, I’m probably one of the few frugal people who refuses to toss out such an old yet working computer, so I don’t expect much demand.

This was an experiment. I have an ancient AMD Phenom II (circa 2009) in my shop with a SSD (essential). It works and runs SnOrca quickly. The latest production AppImage fails because WebKit uses AVX instructions, which this ancient CPU does not understand. Building from source also fails because of WebAssembly deadlocks, proprietary NVIDIA OpenGL conflicts, and hardcoded WebKit paths and, of course, use of the illegal CPU instructions for the old CPU..

I worked with an AI to fix these issues, Whew!

The experiment worked and my old shop computer is back to doing more that watching YouTube videos. My interest was more with the AI but the fruits of this labor are the AppImages for SnOrca and Orca Slicer.

Minimally tested and apparently working on Ubuntu 26.04, Nvidia graphics, and my approaching 20 year old box on modern and much appreciated SnapMaker U1. :slight_smile:

But I don’t slice on that computer, and it still had HDDs.

Glad to see someone else is running such an old CPU.

For me, it’s sometimes convenient to slice on the computer near the Snapmaker U1 rather than walking back to the house to start a print. South of Seattle we get a lot of rain in the winter. :cloud_with_rain:

Best!
