There’s literally someone in this thread right now saying you can eat raw pork in America without worry…

The correct response to that is to provide the actual guidelines based on actual data, not to fearmonger while quoting lines referencing wild game.

A huge part of why commercial pork is safe – that you’re consistently leaving out – were major changes to how livestock are raised. Trichinosis transmission in pigs is primarily caused by the consumption of infected meat; US standards were changed to more strictly control what’s fed to pigs, which led to the decreased risk. The risk remains in wild boar because they’re omnivores that will scavenge whatever they can find.

145 is still a limit people need to follow, lots of people don’t.

145 isn’t a hard limit. It’s the recommended holding temperature for one minute.

The USDA and FDA, which both lean conservative in their recommendations, consider whole cuts of pork safe down to 145F (roughly equivalent to cooked to medium):

https://www.fda.gov/media/107000/download

This has been the case for over a decade. Pork should be cooked but the old 160F recommendations have been gone for a long time now because commercial pork is relatively safe.

Also note that this is the one-minute pasteurization temp; meat can be held at a lower temperature for longer to render it safe.

Nevermind abroad. A lot of them would do well just to get some actual exposure to larger cities in their own states.

Part of the urban/rural divide is fueled by the pervasive belief that cities are lawless hellholes because they’ve never had real exposure to it.

Worth noting that ATC is unusual in that there is both a maximum age that you can start (30) as well as a mandatory retirement age (56).

Sustainability is a large part of Framework’s mission as well. The CEO has explicitly said that one of their goals is that none of their laptops should end up in a landfill.

The transmission in those things is an amazing level of suck, too. It’s this bizarre automatic manual thing that’s just awful to drive.

Stakeholders are people with any kind of interest in the company doing well

Corporate social responsibility as a concept is even broader than that – it’s not just anyone who has interest in the company doing well, but broad consideration of anyone impacted by the decisions of the company.

A company might be able to save operational costs by dumping toxic sludge in a river, but within a CSR framework, people living downstream would be considered stakeholders and the potential negative impact of the decision on those people is supposed to be taken into account when decisions are made. The corporation is supposed to have a responsibility to do right by anyone impacted by their actions wherever possible.

At least that’s the theory. It shouldn’t be surprising that the language of CSR gets pretty commonly coopted by companies looking to whitewash what they’re actually doing.

The wider international community has largely rejected wars of conquest as legitimate in modern times.

The exact same argument could be applied to Israel and e.g. the Golan Heights, but I don’t think you’ll find that to be a particularly popular position.

This AI ruling is also actually completely in-line with existing precedent from the photography world.

The US Copyright Office has previously ruled that a photograph taken by a non-human (in this case, a monkey) is not copyrightable:

That’s a really great point and another reason I’ve really enjoyed the Garmin experience – Garmin doesn’t try to sell your own data back to you.

Getting anything more than the absolute most basic of real time data out of a Fitbit requires an annual subscription. With Garmin, it’s just there.

Fitbit is owned by Google and has the same policy of not repairing cracked screens.

I owned a Sense 2 and was in a bicycle crash. Screen hit the pavement and shattered. Absolutely no options from Fitibit/Google to get it repaired.

I switched to Garmin and couldn’t be happier.

The CEO of Unity used to the the CEO of EA.

It explains a lot.

There’s been an AMD/GloFo fab in Dresden for decades.

That’s inconsistent extrusion.

As others have mentioned, the first thing I’d look at is thoroughly drying the filament. TPU is very hygroscopic and will become nearly unprintable within a couple of days of coming out of the dryer.

Beyond that, you may be trying to run it faster than your hotend can melt it. TPU is pretty resistant to melt and cranking temp doesn’t help a whole lot. Actual flow can vary pretty wildly between brands depending on their exact blend but I’ve seen TPUs that refuse to flow more than around 2mm³/s through a standard 0.4 nozzle. (Volumetric flow is roughly layer height * width * linear speed).

A 2.4 will be better than an Ender 3, but there are better options out there. The flying gantry is a solution in search of a problem, the gantry is heavy and not particularly rigid, Voron toolheads don’t cool particularly well, the rigid bed mounting is a recipe for bed taco, etc.

Which isn’t to say that V2s are bad printers – they can turn out great prints. But if you’re starting fresh today, I’d seriously consider any number of printers over it.

If you want to stay within the Voron ecosystem for whatever reason, the Trident’s a better design. It still lacks things like kinematic bed mounting that are standard fair on other designs today, though. I’d stay away from Tap on any of them – I’m still baffled that thing gets promoted as being a good idea.

In terms of bang for your buck, it’s incredibly difficult to beat the VzBot kits. It’ll be a less expensive and more capable machine than a V2.4. There are panels available to enclose it. I don’t love the Z stage on it, but I can overlook it given the value the rest of the printer gets you.

The Annex K3 is an absolutely killer little machine, but is only 180x180 build volume. The small build volume is free rigidity, though, and K3s can be made true high temp capable with less relative effort than a lot of printers. I’m not as big a fan of the larger Annex printers (K1/K2), personally.

The Rat Rig v-Core was probably the best value CoreXY before the VzBot kits came around. Enclosing them is more of a challenge due to all the PETG parts, though. The EVA toolhead provides a ton of flexibility for mixing and matching parts, if that’s your thing.

In terms of take it out of the box and print, nothing beats the Bambu X1 and P1P. They’re great units. They’re a closed ecosystem though, and not modification friendly if that’s what you want.

My main workhorse printer’s a Railcore II. Great machine, but the design’s aging and I generally wouldn’t recommend a new build today outside of a few very specific applications. It was cutting edge when the design was released in 2018, but, as with the 2.4, the wider community has learned a lot since then about fundamental printer design and there are better options now.

FedEx ground are all contractors. It depends on who has the contract for your area, but they tend to be pretty bad IME as well.

Swap caps lock and left control. It’s the first thing I do on most of my computers, especially notebooks.

The newer versions of Windows Powertoys from Microsoft makes it easy on Windows.

Been easy on Mac and most Linux distros for years.

Restricts Freedom to Use the Software

I’ve always found this particular one somewhat frustrating. It’s essentially the intolerance paradox repackaged into a software licensing analog:

“You are restricting the freedom of users by taking away their ability to close the code and restrict the freedom of other users!”

It’s always read very “I got mine” to me.

That said, while I lean copyleft, I also don’t find just barring commercial use entirely interesting. The goal is to ensure source code remains available to users; I think there are better ways of addressing that than trying to delineate and exclude commercial use.

PLA will mostly get brittle over time as it absorbs water. Biggest issue is that if it becomes more likely to break while feeding. Drying will help some there. On the whole, it’s fairly low in hygroscopicity compared to a lot of other materials.

@galaxi

@zipsglacier

Drying is part of the process when raw plastic pellets are used in injection molding. The only reason it’s not more common in 3DP is that common materials like PLA and ABS arent particularly hygroscopic. PETG is slightly more hygroscopic, but materials like TPU, PET, nylons, etc are highly hygroscopic and definitely need drying to print well.

Also remember that PETG needs more room between the nozzle and the build plate (higher z offset) so that the filament doesn’t stick to the nozzle and make a mess

This is one of those pieces of 3DP lore that isn’t correct. If Z offset is set accurately, it doesn’t need to be changed for any material, but extrusion multiplier/flow does.

The reason why bumping z offset bandaids the problem is because PETs are highly incompressible, i.e., they don’t respond well to being squeezed and will displace under pressure. Raising the z offset means you’re putting the same amount of material into a larger physical volume. This effectively lowers EM for the first layer, but introduces accuracy issues in the rest of the print.

Instead, it’s better to make sure z offset is dead on accurate and then adjust EM down so that flow is correct throughout the print.
