@FrameworkPuter Wild times when running a 3D printer feels easier than dealing with those old 2D ones. 😎

Galaxy Black TPU FTW!

[Prusa3D @Prusa3D]

Prusament TPU 95A is now available in Galaxy Black! 🖤 Tough, flexible, and easier to print than most flex materials, it’s a great choice for grips, RC tires, protective covers, phone cases, and anything that needs to bend, stretch, or take a hit. https://t.co/7gwJrFR27u

@chiptronCZ Super, posílám mámě učitelce! :)

Its official. The Pixel Pump 2 is coming 🔥

Will do a proper introduction video soon but here's a few interesting specs 🧵

(It's a tool for PCB hand assembly)

Can you receive FM radio on a 3D printer's heatbed?

@repkord asked, and we tested, with some assistance from my Dad, a radio engineer!

The answer is yes, and a video is here: https://t.co/6tIZNNSFer

I looked at those slicers too...

CWE-494 isn't just a Creality issue. It is inherited directly from OrcaSlicer, and all the other vendor forks have it too. This means Bambu can inject its own code into all of these slicers. That might be a good reason to submit a PR to @real_OrcaSlicer adding integrity checks, but someone would have to maintain it...

What is unfortunate is that all these vendors forked OrcaSlicer, yet apparently none of them contributed anything back.

At the same time, they all modified the cloud opt-out / libbambu_networking behavior. Creality completely removed Stealth Mode from the UI. Elegoo commented out the control toggles. FlashForge left the option in the UI, but commented out and disabled the backend!!!, so the setting does nothing. Anycubic added its own networking stack, and the setting does not apply there.

Another interesting detail is that the official Anycubic package does not fully match the GitHub source code. It contains 13 additional binaries, and they also removed the Orca-branded models. 🙂

CrealityPrint has very aggressive telemetry. It sends more than 70 different events to a Chinese SaaS platform, Sensors Analytics / 神策, (IMHO) without clear consent. They claim the data is anonymous, but it includes permanent identifiers such as device_id and user_id, along with information about printed models, other printers, and much more. On top of that, the privacy dialog seems to almost never appear.

As for libbambu_networking (used by all vendors), the slicers expose the user's public IP address, the slicer itself, and its usage frequency to Bambu. Once a user logs into MakerWorld (I am not sure all users realize this is Bambu) it can link that to their identity, full printer information, what they print, and their slicer settings (amazing marketing source). Bambu can also silently push arbitrary code to your computer via the libbambu_networking update and execute it when the slicer launches.

@Frogstradamus @Topinka222 Podle dodavatelů komponent je to právě hodně špatný, i dostupnost pro takové množství moc není. 📈

@Frogstradamus @Topinka222 Bude, není to dotovaná konzole. Alespoň mi teď můj SD OLED 1TB stoupl dost na ceně.
