  • I find that it’s best to use 65C for the bed temperature for the first couple of layers, and then drop the temperature to 50C. If you’re using Cura, there should be an option to do that, but you’ll need to dig through the advanced settings to find it. Doing this has completely solved warping for me (Ender 3 Pro v1 with PLA filament). My understanding is that it works because the temperature differential between the top and bottom layers causes a pulling force that causes the warping that you see. I think it’s something about the expansion of the plastic due to heat - as the plastic cools down, it shrinks, which pulls the layer below it upward. The wider the base, the stronger the pulling force. And the more layers you add, the more the pulling force compounds, until eventually the print warps.

    The solution is simple - minimize the temperature differential. You really only need it to be hot on the initial layer, for the print to stick properly. And afterward you only need to maintain a temp that’s just hot enough that the print doesn’t pop off. Hence, 65C initial, 50C for everything else afterward

    Probably less relevant, but I also find that adhesion improves if you have the printer go at half speed for the first couple of layers. Again, there should be a setting in Cura, but it’s in the advanced settings

    I find that I can just use these 2 modifications and everything just works. No need for glue. I just dust off the bed when it gets dusty but beyond that, I don’t mess with it. Actually, the adhesion is quite strong. Even after the bed has cooled to room temperature, I have to exert a bit of force to pull the print off the bed











  • The screen size matters significantly. More specifically, what humans care about is pixel density. A 24 inch 1080p screen does not look the same as a 27 inch 1080p, which does not look the same as a 32 inch 1080p.

    A 24 inch 1080p screen is perfectly fine. A 27 inch 1080p, you can start to see the pixels more clearly. A 32 inch 1080p IMO is unacceptably bad.

    I would say the standard should be 1080p for 24 inch or under, 1440p for 24-27 inch, 4K for 27 inch or above

    I personally run a 24 inch 1440p screen because I’m pretty picky with pixel density, and the monitor was relatively good deal.



  • Duolingo is just a tool, I think. You can’t rely on it entirely to learn a language. And especially you have to take an active role in learning when using duolingo. I’m using it to learn Japanese, and I think I’m picking it up somewhat decently.

    But what I do is that I don’t look at the word banks when translating, and when there’s a listening activity, I don’t look at the text on the screen. I just try to follow entirely based on what I hear. I always say the Japanese out loud, and I try to form sentences in Japanese by forcing myself to think in Japanese (as opposed to thinking in English and then translating the words into Japanese). And, of course, use other resources to figure out the nuances of the grammar and the vocabulary!

    I think if you view duolingo as a way to get more practice with the language, it’s actually a fantastic resource. You just can’t rely on it as an exclusive learning tool

    Also, the Japanese that’s spoken in anime isn’t really colloquial Japanese or really even the same Japanese that duolingo covers. Heavily exaggerated example, but it’s a bit like asking someone to translate Shakespeare when someone is learning English. There will be some words that they can pick up, so your children might be able to get the gist of what’s being said, but the tone and wording isn’t really the same.

    Not to mention, Japanese is spoken really quickly. Iirc, it’s one of, if not the, fastest languages spoken, when measured in syllables over time. You would find better success with asking your children to translate if you find a Japanese speaking online personality who is known to speak slowly and clearly. Hololive is actually pretty good on this front
