    It’s worth it for the dry storage and automatic loading alone. Printing multiple objects one after another on the same bed and same print job, but with different materials is also a great feature and huge time saver for small parts. For actual multi-material prints the best use cases are imo writing into the first layer with a different color or using 2 different non-adhering materials for a thin layer between supports and the part. All of these things require very little filament changes and significantly improve the usage experience.




  • People joke about this all the time, and I here the sarcasm in your comment, but technology has come far since the iphone 6 or 7.

    Most high end phones have wireless charging build it. Between the receiver coil and the rest of the phone is a thin sheet of ferrite material to prevent the electromagnetic field from getting to the sensitive electronics. Battery technology has also improved a lot, so much that even relatively cheap phones like the Realme GT Neo 5 charge at 150W!

    From the technical perspective the limit is the cable and connector, because there would be too much losses that heat up the cable to dangerous levels and rapidly degrade the contact area in the connectors. Manufacturers don’t want to deal with this security risk, not the increased RMA rates within the mandated guarantee period, so they artificially limit the charging rate.

    Thing is: You absolutely can charge at higher speeds if you bypass the cable altogether! A microwave outputs usually somewhere between 150W-1000W, so stick to the lower end to be on the safe side. The screen of the phone must face down, because the charging coil is placed on the back. You also must prevent overcharging by setting the timer correctly: If your phone battery has 15Wh capacity, and you are charging with 150W, you must at most charge for 1/10 of an hour, or 6 minutes (less if you are just topping up your phone).

    One final note: fast charging does put increased wear on the battery, so I only recommend to use it when you need it, for example when you need to make a flight and are already running late.




  • A lot of people here commented “I do X and it works for me”, but I do not think that is good advice. While it might work fine for that person, there are too many variables that are ignored. Ambient humidity, filament type, printer model, slicer settings, model geometry/details - all of this has an impact on the final print quality.

    A more controlled environment removes variables and therefor makes the print result more predictable. Drying filament and storing it properly takes a bit of effort, but it is easy step towards better results.

    You don’t even need a dedicated dryer, just use your printers headbed, put 1-3 spools on it and a cardboard box with a few vent holes on top. Set the temperature according to the filament and let it run for 8 hours. Afterwards put the spools into a sealed container (4L cereal box works great), add some silica gel and your done. When it cools back down the relative humidity drops below 10% RH, which is so low that most hygrometers wont even measure it.

    I’m casually printing PETG at 260°C, over 20mm³/s (about 300mm/s) and archive reproducible near perfect results with next to no stringing. With bare PLA drying may not matter, I’ve too little experience to give a definitive answer. If you have any composite filament (wood, carbon, sparkle, etc) you definitely should dry it anyway, because you do not know how much the filler changes the properties.

    Oh and finally: I place new spools in containers with dry air (a tiny bit of silica gel in them) and measure the equalized humidity after a few days. Most spools were delivered with a humidity of 15-20% RH




  • If you are a company and run a webstore, it could be mandatory that all funds must go through a wallet where the tax authorities have a view key. This would be trivial to enforce with penalties whenever for publicly using addresses that point to other wallets. Peer to peer transactions (for eg. used goods or produce from your garden) are already except from taxes in my jurisdiction, so these transactions can be private.


  • people willing to exchange it for goods and services Never happened.

    This is literally what you do every day. You exchange something for goods and services. This something is money based on it’s functional role, not some obscure definitions. To be money, it must be used as money. To be used as money, a group of people must agree that the item is worth exchanging for. This something does need to fulfill additional properties to be useful, notably it must be fungible, durable, portable, recognizable, divisible and have a stable supply. Gold does fit this description, but so does fiat.

    What you are describing is a government issued currency, which has some overlap with money, but is not the same thing. Maybe you should research on this stuff.

    The idea that money is tied to the state is silly. Many things have been used as money, way before the concept of a “state” existed. Undeniably the money that lasted best across the passage of time is gold. Up until very recently it was the standard to settle cross country currency exchanges with. The value does not come from the state, but from people willing to exchange it for goods and services. Todays fiat money is created at will by a few select people that are not democratically elected. They get to decide how much they debase your savings for the “greater good”, while the ones that profit the most are those who control the source.

    Most people do not care about their open source, privacy and digital rights, so they only hear and care about crypto when the price jumps or when it is used for crime. Everything else is simply not newsworthy. So you end up with a bunch of “investors” looking to make a quick buck and people who believe to solve crime with more laws (requesting ransoms is already illegal, has existed before crypto and currently gift cards are scammers favorite form of payment).

    I never mentioned the price nor suggested investing, because quite frankly, I don’t care. What I do care about is giving the few big companies that control the internet as little data and influence as possible, and not processing payments through them is a really important step. So I keep about as much crypto as I keep cash in my wallet, and use it preferably when buying or selling.

    I prefer free software not for its price, but for the freedom it gives me. Naturally I donate to these causes roughly what I’d have spend on a commercial one. They however do not need to know who I am, so I exclusively use crypto for that. I made one exception for an organization using paypal, and promptly they pulled address and name from that, gave it to a 3rd party which then send a postcard to me. You could see it as a nice gesture, but I think it’s just rude to use data in ways I did not explicitly consented to. Just take your money and leave me in peace.

    In a similar manner I like to use it to pay for email, vpn, hosting and other online stuff. In fact this lemmy instance is 100% paid for by microdonations from its users, and because the provider accepts it directly no conversion was needed.

    Crypto is not anonymous. Even monero, the most private cryptocurrency, has a feature called “view only wallets”, so 3rd party auditing is possible, if not easier then auditing today. Will individuals use it to avoid some taxes? Sure, it gets easier for them. Will corporations avoid more taxes then they already do? Doubtful.


  • I was thinking It would be best to simply offset the inner walls in the xy axis, so that the printer lays down the next extrusion in the groove between two of the previous lines. This is already done with the hexagon infill pattern in orca slicer, but not yet available for inner walls. It would also be helpful to adjust extrusion to deliberately create large grooves bewteen the lines. Outer walls and cosmetic features should of course printed regularly.

    The advantage to OP’s approach would be reduced complexity, less z-hopping and reduced risk of collision with already printed parts.


  • Well their can not be uncapped fractional lending as it is right now. The bank could offer a credit card equivalent, but it would need an equal amount of deposits. The current system works by essentially crediting the merchant an IOU, whose value does not have to be real. With crypto merchants get to choose, would they rather have native crypto, or an IOU with strings and contracts attached? Obviously the latter is more risky, and therefor the seller has to factor it into the price/ transaction fee.

    Maybe that can be somehow circumvented too. But it certainly is more difficult then the meddling that happens right now.

    I don’t use AI to copy other peoples work. I use AI as a better search engine for obscure topics where I don’t know the right keywords. Describe your issue in cleartext, and out comes enough info to migrate to a better search. I’ve also used AI to modify my own works, ie. “blur out the background of this image” or “remove object from image”.

    When people argue in favor of traditional banking because they are more “environmental friendly”, I really have to ask who is arguing ion bad faith. Aren’t credit cards a thing because banks know that given the chance people will consume more then they can afford? They are the one complicit in our consumerist culture, which arguably places a much higher burden on the environment. But the calculation is much broader then comparing the power consumption of ATMs with crypto networks, so it’s easy to sweep that part under the rug.

    AI has the potential to become a tool which strongly favors and benefits the ruling class. Us peasants get the locked down version, while government agencies get to use the full power for cyber warfare and disinformation campaigns, and large corpos get to manipulate (“advertise”) to you in most manipulative way to act in their best interest.

    The way I see it good people shy away form using AI, leaving only the assholes wielding their new would powers. Those with ill intentions will find ways to use it, no matter how many laws you put up to prevent it. To defend yourself the best approach would be to learn how to use AI yourself, so that you can detect and react when AI is used against your best interests.

    Does this make me pro or con AI? I honestly don’t know. Maybe complex things are never that black and white to begin with.
