  • Honestly, my second choice from the Core One would be the Qidi Plus 4. I wanted the X-Smart 3 1803 sized printer as a second machine. But it was discontinued before I got off my butt to buy something. (I ended up with a Bambu mini combo as an impulse buy). But if I was starting over with my first printer, I would seriously consider a Qidi machine.



  • As a bit of Prusa fan boi myself, I too would recommend the Core One over the Mk4s at this moment. It’s a matter of “Buy once. Cry once.” Cheap often costs more in the long run.

    When you are facing a 30 hour print or a long project, a bit extra speed is not only nice but helpful. Plus the heated enclosure can provide access to more engineering grade filaments. While you might not need to print nylon or ABS every day, you will probably find you are going to want to at some point a bit of those types for a project or two. And I believe the Core One also has filtered exhaust air to control nasty fumes that FDM printing can cause, (yes, even PLA has particulates that won’t kill you immediately, but they ain’t good for you either long term).

    Personally, I find the MMU to be a god awful design mess. A rat’s nest of loose tubes and spools of filaments, but it does work. I might consider the Box Turtle over the MMU just for the neatness of the design. I find the multi-filament units, cool for very little color printing I do, but it’s the ability to use up spools that don’t have enough left one them to complete a print by switching to a different spool that can finish the print automatically to be far more valuable. It’s cut down my clutter of mostly used spools to near zero. I paid for all that kilo, I’m bloody gonna use it all dammit.


  • Human drivers struggle with edge cases also. I’ve seen a lot you drive, and as an old medic who has done his share of MV accidents, I can tell you y’all ain’t that good at it.

    While I have no dog in this hunt, all any self driving vehicle needs to be is just a bit better than a human one to be an improvement and a net win, (never let perfect be the enemy of good enough). And historically, as soon as any new technology becomes affordable, humans adopt it and use the snot out of it. The problem is, humans aren’t very good at projecting future harm that any new tech tends to drag along with it.

    A lion can hunt because they come with weapons biologically attached. Humans not so much. And even you could fashion a spear with little effort. Which by your definition would make you a apex predator. And it did so for millennia.

    I’m an old toolmaker that still has a small shop. I could make firearms from scratch if I wanted to. There is nothing special or complex about them. But I choose to purchase them from stores. So perhaps that demotes me from being a apex predator.


  • The problem with new PEI sheets everyone sells, is that they make the PEI so thin that it wears out so fast. It’s like when they go to cut a slice off the PEI tree, they damn near miss the whole tree. And the popularity of textured sheets doesn’t help either.

    I have a smooth PEI sheet that came with my Prusa Mk3s 6 years ago. It has 1000’s of hours of print times on it. After about 4 years of heavy use, it just wasn’t much good anymore. And I didn’t feel like buying a new sheet, so I took the chance and very lightly hit with some 1000grit wet/dry sandpaper to renew the surface. It now holds better than when it was new. And I can probably sand it again if it ever needs it. But new PEI plates aren’t coated half as thick either. So my Bambu plates will have to be replaced at some point.

    Large predators have a species memory that tells them in general messing with a human scent can easily lead to a bad day for you. Because we have spent millennia hunting and killing them. So they have learned to avoid us directly.

    This does not mean that that in certain instances, such as starvation or if they feel cornered and trapped, that you can’t get hurt by them. So when I go out into the forest, and where I live we have black bears, wolves, and now permanent cougars-- and not the ones you might find in a bar on Friday nights either --the only one of those three I find a bit dicey to be around is the cougars. Bears and wolves really don’t like people and make themselves very scarce very fast once they know you are there if there is an open escape route they can take.

    Big cats, on the other hand don’t appear to be the brightest bulbs in the box. And tend to be more of an issue for humans mucking about in the wilds where the cats are found. When I do venture out into areas that I have seen sign or even worse, spotted a cat, I do tend to carry a pistol for self defense in those areas. I’ve not needed to use it and very much hope not to ever need it. But being ‘forearmed is to to be forewarned’ so to speak.

    Smart apex hunters always conserve as much energy as they can during a hunt. Because you don’t know when your next meal might show up. And firearms do make hunting a more sure thing. Hunting game, of any kind, is high risk-- higher reward effort. Most hunters go home empty handed or with little to show for the effort. But, if you do get it right, the effort can be handsomely rewarded.

    So if you are smart enough to develop ranged weapons, you eagerly use them to hunt supper.
