    Yes, I think all government software should be FOSS.

    (Ok, ok. Not all. I don’t think it should be mandatory to distribute software. But if you do distribute software, I think the source code should be required to come with it and there shouldn’t be any intellectual property restrictions on modifying it or distributing it, with or without modifications so long as you include the source code. Aside from that, distributing versions with malware included without sufficiently advertising that fact should be considered some sort of fraud or vandalism.)

    But I’m under no illusion that there’s any likelihood of that happening any time in my lifetime. One can hope, though.

    Of your “possible challenges”, the first two are complete fiction. FOSS would make it easier to properly maintain and update systems, complex or otherwise. And databases and code are two different things. Beyond that, I’ll say that distributing software only in compiled form doesn’t make anything more secure or hide anything about how the code works.

    Edit: Oh, I also think a right to attribution is a good thing. It can be done poorly. (Like some of the earlier BSD licenses that would result in pages and pages of attribution for a single code project.) But done well, I think it’s a worthwhile thing.





  • Not OP, but I have a printer (Ender 3 v2 Neo) with a z-probe that when you tell it to autolevel, it sets the bed and nozzle target temperatures to 0°. (As in, turns both heating elements off.) That’s on the manufacturer’s stock firmware. Even if you preheat before autoleveling, by the time it’s done leveling, it’s much cooler. So autoleveling hot is sometimes not an option.

    All that said, I’ve never had anything like the issues OP has on my Ender 3 v2 Neo. But maybe OP has a bigger bed and that might make a difference as to whether autoleveling on a cold bed could cause OP’s issue.


  • “Still” implies they’re going to get better.

    But that’s such a cop-out. It’s just another grifty way to stir up FOMO and false hype.

    “Trust me, bro, in 10 years, Bitcoin will obsolete fiat currencies when we invent a way to make it actually fucking work at all.” It’s exactly the same thing here.

    The hypothetical technological breakthrough that will magically make LLMs able to think like a human and not hallucinate is completely hypothetical. And the safer bet by far is that it’s not coming any time soon. (Likely not ever.)

    If we develop anything approaching AGI anytime in the next several decades, LLMs and LLM hype will almost definitely prove to have been a distraction that kept us from developing AGI sooner. AGI, if it happens any time soon, will almost definitely not involve the use of LLMs at all.


  • Two theories: first layer expansion and overextrusion.

    If it’s first layer expansion, what’s happening is that your nozzle is too close to the bed when printing the first layer (so, less than 0.2mm if you’re printing at 0.2mm layer height) causing a line of filament to “spread out” more than it should. Over long lines of filament like those on your first layer, that effect can compound. Ultimately it’s trying to put more plastic down between those outer layers than can fit, causing it to “ripple”/wrinkle up. The fix would be adjust your z-probe-offset to make sure your nozzle has just a little bit more space above the bed on the first layer and then autolevel. Or on a machine with no z-probe (with just a z-endstop), to manually level the bed but leave a little more room between the nozzle and bed. If you go too far, you’ll end up with first layer adhesion problems. Like, the first layer will curl up on the corners or will pop entirely off the bed mid-print.

    If overextrusion, what’s happening is roughly the same as I explained above. More filament than will fit is being laid down between those outer layers, causing it to wrinkle. The fix is to turn down your extrusion rate.

    I don’t think I’ve ever had issues with overextrusion myself. But I’m pretty familiar with that first-layer-expansion issue. And to be honest, when I have that issue, the wrinkling I have always happens parallel to the lines of filament on that first layer, while the wrinkles in your picture seem to go perpendicular. I still think those are the first things I’d try, though. So YMMV, but hopefully what I said above helps.

    Also, I’d be skeptical that flotsam or scunge from previous prints could be the problem here specifically. Especially after soap and water didn’t solve it.

    Anyway, my 2¢. Good luck! Definitely worth reporting back if you find a solution!





  • This is a complete tangent unrelated to the OP, but…

    The problem I have with simulation theory is that it feels like it stops short of its own logical conclusion. Like, clearly there’s no experiment you can do to something “concrete” like a coffee mug or a mountain to prove it’s not made of abstract stuff (like numbers, algorithms, data, whatever). That bit’s nearly self-evident at this point in history. But then simulation theory people still seem to believe that there must be a “real world” made of concrete matter. It seems to me more likely that there’s no such thing as “truly concrete”. It’s turtles numbers/algorithms/data/math/whatever all the way down.
