I’m happy they are moving forward and knew Oz would pull it off. Just hurts that they decided to drop Linux support for LightBurn which meant MillMage too. Their apps are writen in Qt so they are portable but Oz is not well versed in Linux and he’s their primary developer so developing for Windows and Mac already took too many cycles which could not be spread to Linux when they added MillMage to the mix.
I was really hoping to see a new well designed and integrated app for CNC on Linux show up.
I have Linux alpha versions of MillMage but that’s it. 
Unfortunately it’s not quite that simple anymore. We have a number of libraries that we depend on that are outside of our control (Qt, licensing, image trace, camera capture, LibUSB, and OpenCV to name a few), some of them have conflicting dependencies on other libraries. There is no solution for that of which I’m aware.
We’re also starting to replace some of the platform specific stuff provided by Qt with our own code (camera capture being the biggest at the moment), and that means custom code for each supported platform.
We were already building 4 different install packages for Linux, more than any other supported platform, for slightly over 1% of our user base. We really wanted to keep it alive, but kept running into new roadblocks.
Everyone who claims, “oh, just use a FlatPack” or other similar hand-waving doesn’t realize that we’ve already been through everything we could think of to address this, and even our most ardent Linux-based in-house developers, who use Linux as their base platform, admitted it wasn’t trivially solvable or worth the effort to do so.
It was not my decision - it was collective, and none of us liked it, but unlike everyone watching from the sidelines, we actually have to live within our reality and make decisions based on silly things like fiscal health and sustainability. 
Sorry, didn’t mean to pull you into this, was just being brief and expressing my sadness of not have a “LightBurn” for CNC option. Believe me, I know I’m a minority on the Linux platform and having been with LightBurn from the very early days have seen the user base grow exponentially as the consumer grade laser market has exploded.
As you might notice, regardless of the reasoning, it still brings a tear to my eye that LightBurn for Linux is frozen at v1.7 but moreso that MillMage for Linux never made it out.
Oh I know - you’ve always been very civilized about it, but that too has been somewhat in the minority. There are a lot of people who seem to be of the opinion that we gave up because it wasn’t making money or we’re lazy.
To be clear, it never made money, but it was worth doing as long as the effort required wasn’t unreasonable
Sadly, that is no longer true, and without knowing the minutiae, armchair “experts” keep lobbing out ideas like “FlatPack” as though the distribution method was the biggest issue. We didn’t make this decision lightly, and all the vitriolic comments to the contrary are honestly pretty hurtful, so just trying to head some of that off before they start.
It has always blown me away how quick you added new features to the product and how well they integrated into the laser engraving/cutting workflow. Only VisiCut had things like camera and library support until over just a few years LightBurn got those features with better implementations and more. And until the refactoring your released bug lists were almost non-existent. Those things were recognized and greatly admired and appreciated.
This group here is less likely to follow the tack you ran across in the LightBurn forums but nipping any possibility in the bud is a good plan. There are only a handful of Linux faithful here and generally they are of the mature variety.
But I do hope to see some Windows and Mac users tell us how MillMage feels to them. Which reminds me, I’ve been teaching a middle school class about circuits, electronics and animations using Botango( a Unity based app ) and had to dig up 30 old MacBook Air laptops for the class and they just run Botango well enough without recommissioning with Linux. If I can pull one out of the lineup this summer break I’ll see if they are up to running MillMage.
