  • How the hell was that even issued? Ianal obviously, my recollection from uni engineering was that Prior Art matters.

    Also, given that there’s a lot of skilled people in the field these days, you’d think some of these patents could be challenged as being “obvious to a skilled person”, bed levelling to me could fit that bill given it’s a common issue that would make sense to pursue a solution for. Granted I’m not versed in us patent law (I barely have a basic understanding of Canadian Patent Law), so maybe that’s different.






  • My partner and I gave up destiny before witchqueen dropped, played pretty consistently since house of wolves with a pause just before forsaken until shadow keep. Absolutely loved the core mechanics and the PvP is some of my favourite, but it just felt so stale, barely any new maps, sunsetting old ones, lack of committing to ideas (4v4 was actually solid, some of the maps do not play well in 6s, 3s are fine though), rotating gamemode playlists like d1 had (for 6s I find control annoying after a while, 3s I liked relic in d1, mix in elimination and I’d be good)

    It’s a shame because as I said, core mechanics rock, slug shorties and hand cannons feel amazing, and fusion rifles are legitimately awesome as well. I have really solid memories of doing stupid things with stuff like the Le Monarque and No Land Beyond. Wasn’t a huge fan of some metas but had some fun times with the games.





  • Was more a thought about if you are concerned about micro fibre particulate (what I took from your post, sorry if I misunderstood) plastic on plastic or plastic on metal are fine for sure, maybe a little exaggerated. Do wonder though about the wear of 3d printed bushings, surfaces won’t be smooth, some of the glass filled nylon I’ve used has almost a soft surface to it, it’s really hard to describe, some post processing though would probably make my (mild) concern moot though so.

    Wrt composites hobbyist/prosumer grade manufacturers (some that target engineering customers in that bucket too) claim they don’t experience the same warping or shrinkage in general, whether or not that’s true I don’t have enough information to tell you unfortunately. Have found both common types definitely have more rigidity, I use them in places where that really matters.

    It’s pretty common to see cheap bearings in 3d printed parts, actually mildly interesting to me that bushings don’t seem to be, at least at the hobbyist level. To go further, how many designs do you see with heat set inserts or pressed in nuts?


  • Shit just even for filament printing, there’s some solvents that get thrown around online that yeah, you really shouldn’t use in a home setting, it’s really easy to get things like MEK, which work, but starting to get into nasty territory for stuff that will dissolve filament.

    Most people do not have adequate ppe or ventilation to deal with chemicals at home, or a fire cabinet, or even know how to find an SDS.

    Semi related, lithium batteries are straight up terrifying, primary cells more than rechargeables, but same idea, I honestly hope no one ever gets to experience an actual full on cell failure, I avoided them thankfully but heard stories of just how much energy is released in even one C or D sized cell going.

    On the composite filaments, abrasive filament sure sounds like a great thing to make wear surfaces out of! There’s a list if things that idk if I’d print, and that’d be up there, ots oil bronze bushings are like, a buck, maybe 2? And they’ll last a hell of a lot longer.






  • Do you have an iPhone or any phone with lidar built in? It’s been a while but I recall it being an option for scanning, make use of tools you already have. I’m not sure what exists for Foss related apps though sorry, and afaik they’re not super accurate (dedicated scanners can get <0.01mm resolution from what I’ve seen but they’re expensive) but if your goal is layout that’d do the trick in my view. Heck, as you said, camera scanning would work, there’ll be cleanup but should be good enough to get you dimensions.

    Another thought, could check with local makerspaces or the like, totally possible they may have scanners you could use, or could put you on the right track. Diy wise, kinects as mentioned, I’m not experienced with these but there are photogrammetry tools, micmac could work, there’s meshroom but that needs some compute hardware and COLMAP could also be worth looking into

    Edit: Photogrammetry is decently accurate afaik, recall sitting in a tech meeting at my last job where the process engineers from the material handling department presented a poc they did with some cheap drones and cheap cameras, they did a fly over of the pier to scan ore piles and apparently were able to get fairly accurate weight estimates from the photogrammetry results, which was really cool to me.



  • If you live near a microcenter

    I’m like a stone’s throw from the border, if they’re cheaper very much consider crossing for that (closest looks like Detroit though, wrong crossing :/) at least for the tap carriage and mount.

    Layer lines are unavoidable imo, I’ve sorta just come to terms, I think I run a tad hot and haven’t fully tuned my profiles, but happy with it for my purposes, and definitely heat soak as well, got a process where I do it right after plate prep/cleanup, then I go do my plating and slicing, gives lots of time.

    LEDs I’m mixed on, I moved my gantry cam because they seemingly were aimed right at it and you couldn’t see anything. I keep thinking about a nozzle camera, but with my current setup I really don’t feel like running another umbilical and I’m not 100% sold that it’d survive or really be that handy.

    How is the rapido? I’m using dragon HF/UHF for spares and using my existing v6 nozzles, have heard the rapido has some good results.
