  • Trying to force people to use a cloud account just to get functionality of the piece of hardware they already paid for with no technical reason behind it whatsoever is ludicrous.

    There is a technical reason behind it which is integration with MakerWorld and being able to browse files from there and send them to the printer remotely from your phone or other device along with being able to watch a live feed of your print and control the printer.

    Again, I won’t argue against the whole privacy aspect as I get it, but I just don’t really think it’s a big deal or something of consequence if we’re simply talking about 3D prints. They do have the option to use them locally now, but apparently this doesn’t include all their models (which you may have mentioned already or it was someone else).






  • There’s nothing to say that they can’t prevent your slicer from slicing some object the CCP has deemed should not be printed, or remotely brick your printer, or just simply refuse to allow their slicer software to connect to it anymore.

    Seems like it’s at least somewhat related to being a Chinese company since you’re mentioning the CCP. I won’t argue that these aren’t things to be conscious of, but I think these fears seem overblown.

    I do support open source projects, but I don’t feel like they really enabled me to do anything I can’t do now with the X1C in the 3.5 years of printing prior to owning this thing and the performance/experience has been so much better.







  • I think it’s honestly a bit embarrassing after reading through this. It states that their “main engineering focus when designing this” was “the exoskeleton, a small chamber, and a platform for the future.” The exoskeleton is just a rectangular frame that nobody is going to give a shit about while printing and the small chamber means a small build plate along with it.

    The main feature they seem to be hyping up is the fact that it has a vent in the body so that you don’t have to crack the door open. This does feel a bit lame with the Bambu, but not anything I really care about at the end of the day.

    I’ve said it before that I do like Prusa represents as a company, but they’re really behind the ball at this price point.



  • No one said anything about permanently

    That’s exactly what Kessler Syndrome is though.

    Because that’s not how gravity works anyway

    This isn’t about gravity it’s about orbital altitude. Objects in HEO or Geostationary orbit can stay at those altitudes for hundreds to thousands of years which qualify as “permanently” for all intents and purposes.

    The thing you yourself quoted says it could take years for it to reenter. So that’s years of too much debris in LEO to launch anything safely.

    No, that just means they can stay up there for years, not that it automatically makes it unsafe to launch into orbit. This is like claiming a 50-car pileup in Des Moines makes it unsafe to drive in Los Angeles.

    I have no idea where you got the notion that Kessler syndrome means something like nothing can ever be launched again

    [From Kessler himself](https://www.nasa.gov/centers-and-facilities/white-sands/micrometeoroids-and-orbital-debris-mmod/#%3A~%3Atext=The+Kessler+Syndrome%2C(900+to+1%2C000+kilometers).

    This cascade of collisions first came to NASAs attention in the 1970’s when derelict Delta rockets left in orbit began to explode creating shrapnel clouds. Kessler demonstrated that once the amount of debris in a particular orbit reaches critical mass, collision cascading begins even if no more objects are launched into the orbit. Once collisional cascading begins, the risk to satellites and spacecraft increases until the orbit is no longer usable.



  • What heel-turn? I stated it isn’t possible for these to cause Kessler Syndrome and haven’t departed from that.

    I did read your links when you initially replied, and they don’t claim that they’ll cause Kessler Syndrome. Some of them dance around the topic with scary sounding premises but none actually state it because it’s impossible for something orbiting flying that low to be trapped in orbit for long just like an airplane with engines that die can’t maintain altitude and continue flying for long. You don’t need to be an expert in aeronautics or spaceflight to understand this because it’s basic physics.

    Yes I focused on that statement that you quoted because that’s what you quoted in your reply as proof it’s possible even though all it said was that more evasive maneuvers are happening as more of these satellites are put into orbit just like more cars will need to dodge debris in the road during rush hour than during the middle of the night when nobody is on the road.

    I didn’t post a list of flat earther links because neither one of us is arguing that the earth is flat. This statement was hyperbole to point out the flawed reasoning in thinking that your position is correct simply because you can find someone else stating the same thing (something those links don’t actually even do if the topic is Kessler Syndrome). Yeah, they can crash into something and cause debris, but they can’t be trapped up there permanently and prevent us from reaching space again because their orbit is so low.

    Will the space debris problem take care of itself?

    In low Earth orbit (below 600 km or 370 miles), the little atmosphere that is there will, over weeks, months, and years, drag the space debris low enough to reenter. Between 600 km and 1000 km (620 mi) it may take tens to hundreds of years for the debris to reenter.

    Starlink orbits at 342 miles so assuming the entire constellation exploded into debris, they’d only be an issue for as little as a few weeks and as much as a couple of years before burning up and clearing themselves out. Kessler Syndrome requires that something be in high earth or geostationary orbit to trap us on the planet permanently.
