No, the light would be reflected as soon as the mirror is set up. If the mirror is set up 10 lightyears away it would take 10 years for you to see it and whatever it reflects. There already is light on the way to the position of the mirror before you set it up.
- Comment on Space is beautiful 1 day ago:
But only after 10 years. You couldn’t see anything that wasn’t visible from the viewpoint of the mirror beforehand, as from earth’s point of view the mirror isn’t there yet. And if you’re there anyway… you can just look at Earth with the craft that’s on the position of the mirror already.

The code is immaculate. Its fully tested as well. No one has looked at the code, they’ve just complained.
Even if that’s correct it isn’t even the main reason why people are pissed about the use of AI. No matter if the code is “perfect” or not, it was created primarily using inherently immoral and outright dangerous tools.

Perhaps it can give you a warning about that in the app. “Warning: Dingdong too long, offspring fountains in danger”

Of course! That health data won’t sell itself.
(The device costs 600$, and to actually get access to your data you then have to pay at least 7$ per month in subscription)

The big fucking constellation of mirrors from Reflect Orbital sweeped over our equipment and destroyed everything. Also his eyes are now toasted.

I can only imagine what those huge beaks were for. Like diving from the sky at some prey, simply punching it straight through it like a huge spear.

Don’t worry, that system is currently being completely fucked by AI as well.

- Comment on Is my stepper motor failing? 3 weeks ago:
It was, in fact, one of those tiny bearings.
- Comment on Is my stepper motor failing? 3 weeks ago:
Welp, it was one of the tiny ball bearings of the extruder gear axle.
- Comment on Is my stepper motor failing? 3 weeks ago:
UPDATE:
It apparently was a damaged ball bearing. Upon opening the extruder once again I found some black grease littered around one of the tiny bearings that’re supporting the extruder gear axle. Replacing them solved the issue, many hours of printing with no angry cicada in my printer anymore.
Would’ve never expected such a tiny thing to make this much ruckus.
- Comment on Filament won't adhere? 4 weeks ago:
Something I didn’t see mentioned so far: have you checked if your nozzle is perhaps too old? I had filament curling upwards and creating blobs due to a nozzle being too old. Especially brass nozzles can wear out rather quickly if you use your printer regularly. If the filament would like to stick to the nozzle itself or move sideways (i.e. curling up when extruded) it rather quickly screws up prints.
Simplest way to check is of course to use other filament.
- Comment on Is my stepper motor failing? 4 weeks ago:
It’s no fan, I checked that. Also definitely comes from the extruder assembly, I could slightly manipulate it if I was pushing on the filament from above.
- Comment on Is my stepper motor failing? 4 weeks ago:
I’ve checked the print it was working on and changed the Z-offset, had no influence on these scraping sounds. It’s definitely somehow connected to the extrusion, that’s why I assumed it to be the stepper.
Do you think those really tiny bearings used for the extruder axis’ can make such a sound? Other than that I’m really out of ideas outside basically sanding down anything that could be the problem… I even made sure to print the whole MK4 extruder you see in the video on the Prusa MK4S of my local hackspace to make sure it has perfect dimensional correctness etc.

This is some prime authoritarian bullshit. Who needs properly declared laws and rules anyway, the current administration are “the good guys”, right?? They’ll just tell you if you’re wrong.

Probably like a huge chicken.
- Comment on Looking to get my first 3d printer, any suggestions? 5 weeks ago:
My guy, first off: the current most powerful printer is the T250, which is 100% open-source. Secondly: Neither Printables (Prusa) nor Thingiverse (Ultimaker) needs a registration for people to download stuff. Not defending Thingiverse or Ultimaker, they definitely also did shit. But that doesn’t mean you have to step right into it (unless you’re into such things). Prusa also made some weird choices (by far not as much as others though). Thirdly: even modern printers with fancy new tech like toolhead switching can and are being build with Klipper as their control software (Snapmaker U1), and Sovol based their company around offering easy-to-use printers with off-the-shelf parts closely based on Voron designs. And I probably don’t need to explain how Prusa operates. None of them are perfect kof course, but there’s zero need for the kind of enshittification Bambu and Creality now stand for.
These cheap hobby printers went nowhere until Bambu started up.
You’re deluded. There’s nothing special about Bambu printers, except perhaps their (by now) awful failure rate and printer recalls. Although it might indeed be special to build printers where the hotend successfully melts itself, the newest problems with the A1 (not the first time Bambu printers are suffering from thermal runaway due to bad thermistors, literally the most dangerous failure there is). The one thing they do like a pro is marketing and capturing marketshare by selling underpriced hardware with increasingly closed software through influencer campaigns.
To call everything that already existed when Bambu was created “cheap hobby printers” is just absurd.
All 3D printing that is practical is backed by VC.
Rofl, so Prusa printers aren’t practical. Noted.
- Comment on Looking to get my first 3d printer, any suggestions? 5 weeks ago:
The older ones can get mostly hacked (not sure about their newest devices), but given Bambu’s increasing reliance on closed source code, custom parts that are not easily replacable and their financial need to lock people into their ecosystem (they’re backed by Venture Capital) it will be a constant fight. And you never know if they’ll lock down something with the next patch. Not to mention that, by using their services, you’re forcing others into soft-dependencies as well (e.g. their model website “MakerWorld” requires everyone who wants to download more than 5 individual parts to register = more data and ads for Bambu).
There’s no reason to buy into something like that.
- Comment on Looking to get my first 3d printer, any suggestions? 5 weeks ago:
If you can stretch that a tiny bit perhaps the Anycubic Kobra S1 is an idea (I think I saw that machine for 369€). Apparently not much for tinkering, but a cheap “just works” device with probably the cheapest upgrade path for multi-colour printing. Its enclosure also enables you to immediately try out more demanding materials like ASA (for UV resistance), ABS or Nylon. And of course PHA, the only truly compostable material (not yet too common, but f.e. Colorfabb sells those).
I see a lot of people recommending Creality. Be aware that Creality is about to go public. There already are signs of enshittification since they announced that plan (incl. a website for 3D models filled with stolen work and AI trash), so I’d avoid them as much as Bambu.
For filament I’ve had some really bad experiences with cheap stuff as well (tangles, air bubbles, dirt etc.), so I’ll add some recommendations too. Mind that this is just my personal experience.
tl;dr Cheap printer: Anycubic High quality printer: Prusa To avoid!: Bambu, Creality
Cheap filament: TINMORRY, eSUN High quality filament: extrudr, Prusament, Colorfabb Recycling filament: Recyclingfabrik (EU), Prusament
- Comment on I'm Unable to get any PETG HF Filament to Stick on the Bed after having Switched from a 0.4mm to a 0.2mm Nozzle [Bambu P1S] 1 month ago:
That’s how I solved my adhesion issues as well (with ASA and a .3 nozzle, but should be the same in principle).
- Comment on Accessibility is important 1 month ago:
I heavily disagree. As a visual learner I need pictures. Everything is visual to me, even math, language, programming… if you give me a wall of text using abstract terms I won’t understand shit. I require graphs, visual representations, mindmaps, something.
It might not be the optimal medium for everyone (there is no universally accessible medium for anything!), but to argue that pictures make things less accessible is just plain wrong.
- Comment on The Saga Of Hacking A Bambu X1 Carbon 1 month ago:
It’s the kind of enshittification Bambu is moving towards. I kind of expect them to do something like this in the near future, only allowing the “correct” filament and hiding the full potential of “your” machine behind subscriptions nust like car manufacturers.
- Comment on Indoor lettuce growing in 3D printed pots 1 month ago:
Depends on the usecase though. If it’s something you could reasonably lose in nature (like markers you put in the ground, small signs and such) I’d rather use pure PHA. It will degrade of course, but that’s a good thing after all. I’d rather reprint some small utilities occasionally than damaging the very nature I’m trying to foster after all.
