Progenitor of the Weird Knife Wednesday feature column. Is “column” the right word? Anyway, apparently I also coined the Very Specific Object nomenclature now sporadically used in the 3D printing community. Yeah, that was me. This must be how Cory Doctorow feels all the time these days.

  • From TFA:

    Manufacturers may comply through three methods specified in Section 6(2) of the bill: integration of the algorithm in the printer’s firmware, integration in preprint software, or a handshake authentication design between software and printer.

    Nobody’s going to do this in the printer itself; the spyware will be built into the slicer.

    Ultimately this will be trivially easy to defeat no matter what moronic legislators who possess no technical knowledge think. The real dangers are more subtle, not least of which being the chilling effect if this passes effectively instructing all 3D printer manufacturers not to sell anything in Washington state since total compliance as the bill proposes is indeed effectively impossible, and the penalties for presumed lack of compliance are high. The most realistic outcome for a private individual vis-a-vis potentially printing a ghost gun is not necessarily having their printer tattle on them, but the state having yet another byzantine felony they can charge people with if they get caught after the fact with whatever-it-is they have. Never mind the 1st and 2nd amendments, the only realistic avenue for enforcement of this on private individuals will run afoul of the 4th.


  • VR never needed Meta. Us nerds have been trumpeting this fact since before the first Quest even launched and for some reason everyone insisted on relentlessly bickering with us about it tooth-and-nail rather than accepting the simple reality that Zuck Zuck would continue to burn money on his silly venture with creepy knockoff Miis that nobody wants until he finally lost interest and gave up. And no part of that process would result in Meta becoming the “savior” that revolutionizes VR.

    Well, here we are. Where’s my fucking gold star already? My message has been consistent on this since about 2016.




  • I’m in agreement with the others. This is a printer issue, not a model design issue. Any current printer in good working order and running non-insane settings should be able to print a 90 degree inside corner like that with no problem.

    Some possibilities:

    Your Z offset may be set too high, so that your first layer height is too tall. This will result in the first layer’s extrusions not sticking to the bed and each other, peeling off in strings like you see here.

    Flip this over and show us the bottom of it. The effects of a too-high first layer should be readily apparent. That’s where my money is.

    Your printer may also be attempting to round the corners too fast. You could slow down your print speed, or adjust your linear advance settings. If you are using Prusaslicer or a derivative thereof (Orca, Qidi, etc.) there are built-in calibration prints you can run that will provide you a range of values to inspect my physically printing them, and allowing you to choose from the value that produces the best looking result. Ideally your linear advance/pressure advance setting should be tuned for each spool of filament, but in reality most people (myself included) don’t bother until they observe an issue. I use the same settings for all PLA, and a different set of settings for all PETG, and another for ABS, etc.










  • The intent of the Steam Frame was never to compete with a PCVR rig in standalone mode and don’t recall anybody ever saying it was. Valve explicitly stated that it was to be a “streaming first headset.”

    The Frame technically has a slightly more powerful chip in it than the Quest 3 so should outperform the latter by a small margin in theory. The Frame also has eye tracking whereas the Quests do not (except the Quest Pro, which is NLA and was ~$1,500 even when it was) so the potential is there for foveated rendering to enhance framerates if developers actually bother to support it in the future. For pure standalone VR performance with native games, the Frame should outperform the Quest 3. PC games run on the headset in standalone mode will have to be done through a compatibility layer, which is probably not 100% optimal for performance. But for what it’s worth, the various Quests can’t play PC content at all so I’m not sure what the complaint is there.

    In the Enterprise editions of Windows, you can already uninstall it. Maybe not via group policy, but you can just find it in the Apps > Installed Apps list and right click to uninstall it. On the various home user editions of Windows, this is probably not the case. (I have zero systems running those, so I can’t check.)

    The Enterprise LTSC IoT version of Windows 10 doesn’t even come with Copilot, nor have any updates for it thus far installed it on any of the systems I administer, either. Apparently only 11 does.

    What’s new here is apparently being able to trigger this via group policy, but for anyone in the here and now you can already disable Copilot via group policy as well, even on your local system, even on Windows 11.
