  • It's actually not the projectile that causes most of the lead exposure for shooters. It's the cartridge primers, they use lead styphnate for their explosive. Copper bullets are mainly to not spread lead through the environment where it can harm wildlife, and to avoid the risk of consuming lead in shot animals.

  • I went with the Qidi Q1 Pro and I've been very happy with it. Orca Slicer's built in profiles for it have worked great so I didn't have to tinker. It runs Fluidd so once it was connected to the local network I could monitor and control it that way (and it will display directly in Orca Slicer).

    There is a setting in the printer's interface to restrict it to local network only (and just to be absolutely certain I blocked it in my firewall as well). There are no penalties for not connecting it to the internet.

  • Canon does make Linux drivers for at least some of their printers (like mine), but they can be hard to find. I can't remember exactly how I got to mine but I know it took a few attempts.

    Maybe you're particularly unlucky though, because my Canon works perfectly with either the built in CUPS driver or the one from Canon.

  • If you average out the low precision, high accuracy shots you will get a single point as your result. If that point is not already in the dead centre, then increasing accuracy is simply a matter of shifting that point closer to it. You can do that without increasing precision by moving the entire shot spread in that direction.

    I've found this analogy often confuses people because in the shooting world the terminology is a little different. There the high precision spread would be considered high accuracy, with it only being a matter of adjusting the sights to get it on centre. And nobody is winning a shooting competition by arguing that the average of their shot spread is in the centre.

  • I was watching live when Trump called in, and the astronauts were clearly trying to emphasize the benefits of diversity and co-operation, and I'm quite sure none of that sunk in. Trump was too busy mispronouncing names, not knowing the difference between the name of the mission and the name of the craft, big noting his own role in funding NASA (while his administration has been actively attacking NASA) and generally waffling on because he likes to listen to himself speak.

    The next call after that also had the NASA director comment something like "I'm sure this call won't be as special as that last one" whereupon commander Wiseman burst out laughing so I'm pretty confident those involved in the mission are not in Trump's camp. Which is to be expected, because their jobs require them to be humans with functioning brains.

  • It's great being in a time zone where it's already April 2nd when the Americans start pulling this shit. You think you've made it through the nonsense and then BAM, here's another day of it except ramped up to 11.

  • I've been able to freely export .step files for anything I've made in Onshape. As another commenter said there are catches, like all your files are public if you're using the free version and there are premium features that require payment. But it's currently not locked down like it seemed Autodesk were preparing to do, where all your files live on their cloud only and can never be exported. For sure there is potential for the same enshittification with Onshape though, which is why I hope the freecad devs soldier on.

    Also if you're worried about your files being public, just name them with codes indecipherable to anyone but you. It doesn't seem like the public file repository actually gets searched that much in general, and with a meaningless code the odds of someone finding and stealing a specific design are probably near zero.

  • Time to give it another try I guess. I used Fusion almost exclusively until I switched to Linux (and have also used Solidworks in the past), and I found freecad 1.0 to be an exercise in frustration.

    I gave it a very solid shot, but after many hours messing with it and watching tutorials I decided to try Onshape instead. I was able to become comfortable and productive in Onshape in less than half the time it took me to lose my cool with freecad.

    The 1.1 update looks to be addressing some of the pain points, so they seem to be on the right track. I hope they keep that momentum going.

  • What about all of the site-to-site VPNs?

  • The Ender was good when it worked, which it did really well for a year or two after I spent a lot of time and energy getting it sorted. But then things started to go downhill. In the hot end I had the heater cartridge, thermistor and cooling fan all fail separately but fairly close together. I had Z screw runout issues and had to replace the brass nut. The extruder housing cracked and had to be replaced with an aluminum one. Limit switches failed. V rollers failed. It suddenly developed adhesion issues with the glass bed and glue stick I'd been doing for years. Scuffing up the bed didn't work, replacing it with a new glass bed didn't work, scuffing the new glass bed didn't work. I switched to a magnetic PEI bed, that worked but it conforms to the horrific banana shape of the Ender's factory bed and I can only print on a single quadrant of it at a time because of the massive dips in between the screws.

    This is just the stuff I remember from years ago. I enjoyed tinkering and upgrading the Ender in the early days but I'm older now and have other stresses on my time. I just want something that works.

  • Thanks for the advice everyone. I've been researching the suggested printers, though options are somewhat limited in my area and pricing varies to US retail. I'd hoped the Ender 3 price tier had approached a more turn-key experience by now, but it seems pretty hit or miss with the Ender 3 V3 SE as far as I could tell. It looks like out of what's available the Qidi Q1 Pro gets me what I want and is the best bang for buck in local pricing.

  • Of course that's a thing now. Yeah I would very much not like to be locked into a vendor ecosystem.

  • 3DPrinting @lemmy.world

    What's a good entry level printer these days?

  • Yep. To paraphrase the wise words of Casually Explained:

    Adrenaline junkies like skydivers often say something like "I love it so much I'd die for my sport". In contrast, with bodybuilding dying is the sport.

  • I know this is a funny jab at BMI, which is an extremely flawed way of determining anything, but actually the risks of being a competitive bodybuilder with single digit body fat percentage are remarkably similar to being morbidly obese. Being natty certainly makes it safer but being jacked and being healthy aren't the same thing. The people you see on stage at bodybuilding comps are a short step away from needing admittance to hospital.

  • I enjoyed playing Andromeda, in fact I think gameplay-wise it's the most fun of any mass effect. But story and character wise it was so mediocre that very shortly after finishing it I couldn't tell you who anyone was or any of the things that happened.

    It might have been better off with a different spin-off name that made it clear it was in the same universe but wasn't really Mass Effect, because it kinda misses the mark for what those games were about.

  • Balena started collecting telemetry without disclosing it to anyone, reportedly including information about what images you were flashing. Apart from a general distaste for unconsensual telemetry, I think people were concerned the data could be used for things like helping to de-anonymize TAILS users.

  • Beat Saber is on Steam and is also the best selling VR game of all time, so yeah I'd say it will work. I'd be extremely surprised if it wasn't one of the very first games Valve worked on FEX & proton optimisation for.

  • True in many cases but not all, and the people managing these populations are almost never directly responsible for the problem. For example the species I now help manage in my country were introduced generations before my birth. Same for the overwhelming majority of the land clearing, it was done before even my parents existed.

    I can't change history, but I can take some responsibility for mitigating the damage of those who came before me.
