  • There are also still a lot of QoL issues with the GUI and no real attempt to bring in influences and widgets from direct modeling. FreeCAD is pure of heart and pure of thought, but I’m not sure I’m quite there, though I can at least imagine it now

    fyi, there is now ondsel
    based on FreeCAD, their release introduction reads:

    So our thinking was: we should focus on a polished user experience and features that are essential to professional use. Let’s build something we feel good about recommending it to someone working on a deadline. And let’s build a service for vaulting and collaboration.

    Our primary objective is to provide polish and sorely missing features — that’s a large part of the added value. We’ve made big and small changes in the upstream project, but the four vital projects for us have been toponaming, integrated assembly workbench, UX/UI, and collaboration.

    full Article / release notes

    So working exactly on what most consider FreeCADs weaknesses I’d say

    Unfortunately toponaming is still not done for either. That will be a huge leap in usefulness for me.
    (fixes models breaking when their topology changes)


  • Infill has massively diminishing returns. I don’t think 100% is required. Usually it’s much better to increase the number outer layers.
    That said, depending on the cost scaling, the possibly positive effects of extra mass, and how much I want to avoid a second attempt, massive objects can make some sense.

    PLA becomes brittle with moisture (from your hands and/or air). I would recomment PETG / ASA / ABS (ascending order).

    Yes, basically all CAD and slicers (3d-printer software) can mirror. PrusaSlicer for example can mirror and then save to stl again.

    A lot of people seem to to think that bedslingers are inherently worse than core xy kinematics.
    Core xy is definitely more compact.
    In return the belts are longerz tightening them more complex (x and y can become unaligned).
    Core xy can be easier for input shaping, as only the z axis mass changes.




  • If you are relying on T&C as a get out of jail free card for your safety system, then it isn’t a safety system.

    That’s how every safety system works.
    You define the necessary conditions in which it works, and guarantee (with testing and validation) that in those conditions it does its job.
    Nothing works unconditionally.

    The Conditions in this case are in fact, that it is an assistance system, and not a safety system, because everybody knows it can’t be relied upon. It probably works >99% of times, which just isn’t (nearly) enough for driving.


  • Then it should not be called “Autopilot.” The AI required to make real autopilot work does NOT exist now and probably won’t exist for decades.

    Well, in Aviation, where I believe the term “Autopilot” is most commonly used, at least before tesla, an Autopilot is actually exactly what Tesla offers.
    When everything is fine, it can keep the plane going.
    If issues come up, it disengages and the pilot has to be able to receive full control

    /e: also, waymo and cruise already have completely autonomous cars, which generally work.



  • if it disengaged a few seconds before, the crash is still the fault of Tesla’s software.

    I actually disagree, because it’s not self driving, it doesn’t actually claim to have any autonomous features. The driver has to be aware all the time.
    The way all of this is worded when facing the public is… horrible, that’s true. But since the warnings once in the car seem to all be there, I’d say that’s more a false advertising issue than a “is your product actually safe?” issue.

    Really interested in how this comes out, even more data would be interesting to me.
