I _think_ that's browsing the SD card from Bambu Studio when the printer's set to LAN Mode, not printing from SD on the printer itself.

Yeah this looks to be the case. All of this change was prompted by the fact that malicious software was triggering prints over the network. So now they have locked it down so the printer can verify prints came from the actual account owner. Printing directly from SD cards via the little touch screen is unchanged since networked computers can’t do that.

The ONLY problem I have ever heard of Bambu printers starting on their own was when Bambu itself had a problem with cloud:

I have owned one since November 2023 - and it has never been hacked or powned by an outside actor.

With 3D printing out for a while now, there's zero good reason IMHO that there isn't a 2D-plotter retrofit which allows someone to attach one or more [colored] pencils or pens. I'm really shocked the overpriced ink monopolies weren't attacked in this manner, as a young child I distinctly remember a kiosk in a grocery store which 'printed' messages and images on blank cards using colored pencils, for customer order. N…

> I'm really shocked the overpriced ink monopolies weren't attacked in this manner Because those of us who understand mostly don't care. Those who know bought a Brother laser printer and got on with life. When those who understand need genuine inkjet prints, we go to a store that owns a printer that is several orders of magnitude better than we will ever need and pay them a pittance to get it printed. That having bee…

Man, I love my Brother - it is 10-years old this spring, driver updates keep coming for new operating systems in both 32/x64 - and never has a hassle with third-party toner cartridges. While it is intended for a small office (and therefore fairly large and heavy), it has been easily hands-down the best hardware purchase decision I have ever made. (And - it there was a $300 off sale discount when I got it - so $500+tax)

...and? Applying to all brands equally doesn't make it okay.

I am saying it doesn’t matter whether it is open source or not.

... well... stepper motors, motherboards and v/t-slot extrusion can be used for many other things than 3d printers...

If they are going to regulate this, then why not CNC machines? Lathes? Drill presses? Pipes and lumber?

Imagine Ford deciding their cars must drive at 50% their speed when the engine oil is older than 2 years and at the same time forbidding users from changing the oil. Yet there are always people justifying these type of awful practices as better for users. These aren't, the measures are only good for business.

Ford actually does this. They have something called limp mode for when sensors detect degraded conditions. They won't honor the warranty if you clear the code manually and continue operating the vehicle. Many cars enter limp mode for when the ECU senses a possibly damaging condition. This limits the performance and capabilities until someone with a diagnostic computer can plug it in. Many times these diagnostic compu…

Well, that still wouldn't reduce your car speed by 50%.

And even for that case there would be a warning on the console and a mechanic would be able to inform what is happening. On this iphone case, there was no warning at all on the device nor there was any disclosure that they would be doing this to the phones.

You know this. In either case, thank you for the ECU info.

Have you driven a German car ever? They are SO LOUD if you don't service them at regular intervals. They're even doing fancy tricks to make sure you're not faking the service.

Yes. I live in Germany, drive German cars and know the tech.

Regular service is indeed a bother. You know what I hate the most? In my oldish Mercedes it isn't even possible to change/update the hour without using a proprietary tool only available at official Mercedes mechanics. Since I refuse to pay premium cost for attending their mechanics, the clock on my car is always with wrong time.

And let's not even get into new business models like charging you a subscription to unlock the car to move faster or to unblock the heated seats. Indeed they also have quite "creative" ways to squeeze money and force to get new models.

Because violent criminals tend to lack wealth, knowledge, and skills. Nobody in the hood about to knock off a 7-11 has a tormach at home and the gcode for a reciever queued up.

these printers have spaghetti detection so it actually makes sense the camera is always on

Spaghetti detection is supposed to happen on-device.

Yes? the reddit guy is saying the device is always saving pictures on the device.

Yep laser printers are the equivalent of modern CoreXY printers with solid auto calibration

Could you name one? Other than the X1. I think I might be in the market for a new printer, but I don’t want to lose quality.

Prusa core one, but given the lack of features I can see why people might choose X1.

My toilet doesn't officially support crapping without an internet connection either. I'd argue that in both cases it's implicit unless very explicitly disclaimed.

How would a toilet with no electronics require an internet connection?

Thing is even with the core one finally releasing...its not a compelling product. It costs more than the P1S - which lets fact it, thats what it should be compared to, not the X1C as the Core one doesn't have the stronger nozzle, nor any features that would make it a 'pro' level product. They also still dont have an answer to the AMS, which is a big selling point for the Bambu's. The MMU3 may be better than the previ…

It would be interesting to know how many people buy printers with AMS or other multi-material capability. How big of a selling point is it really?

Was quite important for me, screws hassle in switching spools.
