I sort of made a bipod.

@RepPatHarrigan 100% Right to repair or our own government is subservient to defense contractors.

For 20 years, a $6 knob that takes one hour to 3D print has been grounding Black Hawk helicopters four times a month, and the contractor responsible won't sell us the part or the IP rights to fix it ourselves. So instead, American taxpayers have been paying $40,000 every single time to replace the entire system, multiplied by four times a month, for two decades. That is NOT a procurement problem, that is a shakedown, and it is exactly why right to repair has to be in this year's NDAA.

@themitch22 @geerlingguy @BackwoodsEnginr I'm arguing for a more diverse supply chain for a sub-line of printers. Source parts from Taiwan, Portugal, even Italy (some electronics) to save on cost, try to make it competitive. Unlikely it will ever happen, but it's a case I'll continue to argue for.

@VAT_Engineering @geerlingguy @BackwoodsEnginr Prusa Mini is a solid machine, but the price of them is still higher than the equivalent alternatives because the base hardware costs will always be that high (when you’re not subsidized by filament sales, investors, governments). Heck, a $600 Positron can perform is on par.

Bambu Lab 3D printers: never again. They're breaking the open source social contract (for the nth time...), and I'm past hoping they'll amend their ways. youtube.com/watch?v=eb48Md…

@CanuckCreator @geerlingguy @BackwoodsEnginr @Prusa3D Electronics alone are the majority of the price if I recall correctly. They need to line up a solid supply line with other non-China countries. They could seriously sell a mini printer for $399 that outperforms almost anything in its class.

@geerlingguy @VAT_Engineering @BackwoodsEnginr id love to see a prusa core mini, but unfortunately and i believe @Prusa3D could back me up on this it would cost too much scaling the size down of a printer doesnt really save much $, still same electronics, slightly smaller bed, still need the custom frame etc

Jeff speaks the tru tru We need a user friendly consumer printer that people can afford. Especially one that doesn't sell your data too.

They need to put @themitch22 on the case! I own a whole army of prusa minis, not for a farm but because they're awesome! Best printer idea they had, compact for shipping, user assembly in minutes, (initially) low price. It would be the best selling printer ever if they let Printed Solid optimize it for manufacturability (including opting for lower cost controls). One can hope. Unfortunately the core one mini community project never really saw any support from Prusa either.

@VAT_Engineering @BackwoodsEnginr I wish they'd bring back the Prusa Mini, but like a Voron mini, but like this: printables.com/article/core-o… :)

@GrandpaRoy2 Tried to get a project going for that in the USA. I couldn't convince people to use cheap fiber optic lines over a massive proprietary relay radio system that is unrecoverable. 🤦‍♂️

An Israeli drone reconnoiters a Hezbollah tunnel in Lebanon. The high-resolution, static-free video feed captured while operating underground strongly suggests that a fiber-optic-controlled drone was used for this task, as the IDF has previously done in Hamas tunnels in Gaza.

@CooperZurad Process optimizations. But also, materials and equipment are outrageously expensive in the US. Wish there was a way to solve that at lower levels.

One must be ideologically committed to make an even remotely affordable American printer One must also probably be dumb

@jakkuh_t @Prusa3D A gaming computer with a 5080 is cheaper.

buy a @Prusa3D. problem solved

@geerlingguy @BackwoodsEnginr The primary issue for average consumers is price. $900 flagship 4/5-color Bambu VS $2,000 single color Prusa. Prusa has become complacent in areas that make it hard to scale and manufacture efficiently. They lack a consumer-facing printer.

@BackwoodsEnginr Either spend a bit more for a Prusa (and deal with their multi-filament solution that's not as good until INDX comes out), or buy a similar cost clone from Snapmaker, Creality, etc. Or go Sovol and get a nice more open hardware platform.

BambuStudio has been violating PrusaSlicer AGPL license since their fork, with the same networking binary black box in question today. Why are they willing to burn the goodwill over it? There's something most have sensed but never seen it all in one place, the five-law framework China built between 2017 and 2023 ⤵️ So maybe their hand is forced as their "network" is too valuable already? Each law on its own, interesting, okay... Read them together, and add any Chinese company with big reach to the mix you get the complete picture. 1) National Intelligence Law (2017) All organizations and citizens must "support, assist, and cooperate" with intelligence work. The same law makes it illegal to disclose that cooperation happened. Cooperation is mandatory, and silence about it is mandatory too. 2) Cryptography Law (2020) Commercial encryption must be state-approved and state-reviewed. When authorities request it, companies must provide decryption keys or plaintext. The state on both sides of that equation is the same one. 3) Data Security Law (2021) Article 2 gives the state extraterritorial reach over data that touches Chinese national security or public interests. So EU/US data hosting does nothing to make it safe, because jurisdiction follows the company, not the server location. 4) Counter-Espionage Law revision (2023) The general definition of espionage was expanded to cover "documents, data, materials, or items related to national security and interests." Industrial data is one of the intended targets since the revision. 5) Network Product Security Vulnerability regulation (2021) Any company or researcher that discovers a software vulnerability must report it to MIIT within 48 hours. From there it flows to CNNVD (China National Vulnerability Database of Information Security), operated by the 13th Bureau of the Ministry of State Security. Microsoft's threat intelligence team documented Chinese state-hacker zero-day usage rising after this took effect. Shows the willingness to use the “tools” China built. Together they describe a system with no neutral exits. Cooperation is required, encryption is real but the spare keys live at the ministry, jurisdiction follows the company across borders, industrial data is in scope, and discovered vulnerabilities flow to an intelligence agency 😬 3D printing became strategic for China in 2020 and joined the “Made in China 2025” plan soon after. Why does 3D printing matter so much? 1/x

All I want for @America250 is an “American Made Products” filter on Amazon dot com

@i2cjak $15k per patent to have a lawyer do the stuff. It is a mess.

"DUDE YOU HAVE TO PATENT THAT IT NEEDS A PATENT GET THE PATENT BRO!!!"

@Atlas_Leather @MarcLobliner Indeed! I can eat homemade food in the USA for the price of the cheapest street food in Taiwan.

@MarcLobliner Buys the most expensive version of everything: “why is this so expensive?”

I have a family of 5 with two athletes bulking in the offseason and I eat a lot. We aren’t even close to this. If you’re shopping at Whole Foods, you’re going to pay much more than us peasants who know how to budget (even though I don’t budget food) and where to shop.

It is time for the United States Postal Service to ban junk mail. Unsolicited spam calls are already prohibited by the FCC. Emails are heavily regulated by the CAN-SPAM Act of 2003. Junk mail is the majority of mail, 100 million trees per year. Enough!

@pnwguerrilla Not as good as it tastes 🤌 Nothing tastes better than a local cow.

Bought a 1/4 cow. Feels good man.

@CooperZurad @josefprusa No worries, just tossing idea grenades while I fade into my nightly unconsiousness. Keep on rockin' 🤘

@VAT_Engineering @josefprusa Maybe, but we're talking about a significant amount of complexity to trade for what might not be a huge net gain

Re: needing waterproof prints I could probably order 2 CNC mold pieces from aluminum and hot press FDM prints.

@CooperZurad @josefprusa Any chance you could use a belt to keep it above the water line?

@VAT_Engineering @josefprusa I don't have the luxuries of cost, scale, complexity, etc that industry has and have to be alright if this motor only lasts like 100 hours or something

@Tyler_Plummer Powder metallurgy is more efficient. But like castings, nobody does it as much anymore. We need to make more of the all the things.

You may or may not realize all of the Castings you walk by every day such as this one. We ship roughly 300k pcs annually

@BattleByrd When you can't run, you learn to shoot better.

That duty belt is holding on for dear life...

@DonutOperator On a train in taiwan. We are surprisingly the same (train manufacturer), but with snacks and drinks.

On a train in Japan. Ask me anything.
