  • 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.


  • I don’t think it’s necesarrily nothing, as sending all of that data is so comprehensive it should be communicated clearly by bambu, and it seems (but I don’t know!) That it isn’t.
    Sometimes you might want/need help and don’t want to send everything.

    For a lot of stuff partial gcode / sensor data around the issue should suffice for example.

    But it sounded way worse before the clarification, when I understood that it was sending those logs all the time.

    The open source license issues will be interesting, but probably irrelevant. We already can be rather sure that they already are in violation with BambuStudio and no one wants to spend the money to do anything about it.

    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.

    I bought Prusa.
    I hope to be able to still use the machine in 10 years.
    I’m much less confident that BambuLabs machines will be able to do that, than Prusas. This is because of multiple reasons:

    • There are design decisions of Bambu that I do not trust (bushings on the x-axis on p1 and x1 machines), which track with the decisions of DJI which I didn’t like and where many of Bambus people came from.
    • I much prefer to support a comparatively independent european maker than a chinese-bank backed one.
    • I do trust Prusa much more to offer long-term support than Bambu
    • I prefer to support Open Source, and I do think Bambu is still violating licenses (which imho should not be supported/accepted)
    • I do not like Bambus AMS design. Their reliability costs quite a lot of filament.

    But Bambu has Prusa beat on price for similar performance. By a significant margin.

    And to further your question, I’m not sure Bambus Printers have that much more “simplicity” in use than Prusas. Especially if you buy pre-built. Both are rather plug and play.

    In short: I fear / believe that Bambu is exactly the kind of company that ruins products. Underbid your competition, cut costs at the customers expense. Why provide updates to your old products when you make a new gen? Why use a part that lasts longer than the required period for repairs? etc.
    The fact that they started regular sales this year (I Believe before was pre-order?! would have to check) and already have 3 different platforms out (X, P and A) is quite a lot of fragmentation. Maybe they designed for that from the start, but… we’ll see. AMS and AMS lite also seem quite different.
    They may even be the worst kind, that underbids the competition and takes development costs as losses to destroy the competition until you are an effective monopoly, at which point you can fuck everything up way more (increase prices, cut quality / development etc)
    In Fairness, they may also not be. They may also have excellent long-term reliability and support. Maybe in 5 years P1 and X1 still get feature updates. Maybe the design decisions turn out to be outstanding.
