- Comment on Condoms and contraceptives to become more expensive in China as Beijing accelerates push to lift birth rate 1 day ago:
Economically stable people who feel safe in their society choose to have children
This logically makes sense, and may have even been something that you’ve experienced yours either directly or second hand via friends/family, but it’s not present in the data.
There’s a very strong negative correlation between education and income vs birth rate. As people make more money and/or attain higher levels of education they have fewer kids. My theory is that this is due to a combination of reliance on direct family for labor on a homestead/farmstead, sex ed, and access to contraceptives. Kids are also a large time/emotional/financial commitment and with our modern emphasis on “self sufficency” this places a heavy burden on parents. Some countries have tried softening this blow, but it hasn’t changed their birthday trend.
- Comment on I'm doing something wrong; can't print this PETG 6 days ago:
Good to hear! The only PETG problem I ever had problems with was an opaque white. Evidently it takes a decent amount of additives to get it to be both opaque and white, which can impact printability.
- Comment on I'm doing something wrong; can't print this PETG 6 days ago:
Sorry to hear that. The only thing that comes to mind is potentially print speed. Your first layer is probably pretty slow. Are your subsequent layers much faster?
- Comment on I'm doing something wrong; can't print this PETG 1 week ago:
Did it look more solid or did print quality basically remain the same?

How can you tell it’s under extruded?
IMO this is the same as any other hobby. Print enough and you’re likely to run into under extrusion at some point. Similarly, I can tell if doughs and batters needs more liquid or more flower by look and touch thanks to making a ton of pizza crusts and pancakes.
If there’s some clear sign of under extrusion it might be useful for my reference doc I use when trying to troubleshoot failed prints.
The first photo in the album looks like ‘classic’ under extrusion. The layer lines are largely intact, but way less material that is necessary for a solid print is present. The print has better and worse areas, which usually indicates a clog. Combine this with the fact that PETG will clog if you use too much retraction and a user that’s new to PETG and retraction seems like a good place to start troubleshooting.
As for helping your guide, simplify3d hasn’t been a ‘cool’ slicer in quite some time but they have a decent print quality guide that names a bunch of failure modes. Ellis’ print tuning guide is the best one I’ve come across.
- Comment on I'm doing something wrong; can't print this PETG 1 week ago:
PETG isn’t very tolerant of too much retraction. Given your fine first layer I suspect you’re developing a clog as the print goes on, which would result in under extrusion. Turning retraction completely off will make it very easy to rule out as a possibility.
- Comment on I'm doing something wrong; can't print this PETG 1 week ago:
You’re severely under-extruding. This may sound weird, but try a warmer temp tower without any extrusion. You might be developing a clog mid print.
- Comment on Snapdragon X1 Elite Linux laptop cancelled due to performance concerns — Linux PC maker says Qualcomm CPU is ‘less suitable for Linux than expected’ 1 week ago:
I’m not an Apple fanboy, but arm based processors seem to be working out fairly well for them.
I own an Lenovo Yoga Slim 7x, which was one of the OG snapdragon x laptops released a (two?) and a half ago. It took a while for folks to get Linux to run on them and there’s enough of a barrier to entry that it’s still not very common. Most of the initial hurdles were due to Qualcomm bootloader shenanigans.
- Comment on Valve's new hardware will NOT be loss leaders 2 weeks ago:
You’re 100% correct at a sane company. At my employer the hardware team is incentivised to cut costs and impacts to productivity are someon else’s problem. Corporate metrics lead to some pretty hilarious situations.
- Comment on Decent 3d scanners under $1000 2 weeks ago:
I’m not going to try to dissuade you from getting a 3D scanner, but for functional prints a pair of calipers, some radius gauges, and a profile gauge will you really far. Once you get some reps in with CAD it also won’t take you long to model your designs. CAD is a great skill to learn and as you do this again and again you’ll start modifying your designs to make them easier to print.
- Comment on Crappy filament? 3 weeks ago:
Very nice! Welcome to the joys of designing and making functional parts. I suggest doing two things:
- Print, or buy, some radius gauges
- Make some test parts to understand how your filament and printer behave. For example, materials like ASA will shrink. I’ve also found that outer dimensions are much more true to CAD than inner dimensions, especially for things like smaller diameter holes for threads. Some text prints will help you figure out what input results in a given output
- Comment on Crappy filament? 3 weeks ago:
Way back when there was an American filament company that sold… very reasonably priced filament that actually printed well. As they got more popular they couldn’t keep up with demand and it seemed like they started cutting corners. This resulted in their filament not having a consistent diameter as well as the occasional foreign object in the filament (a bit of charred plastic?), which lead to jams for many of us. They ultimately went out of business due to their reputation of struggling to fill orders and inconsistent quality.
If you still have the chunk of filament you cut off and also have some calipers I suggest measuring the end that you were trying to feed into your extruder. You could have had a physical clog, especially if your extruder was clicking.
- Comment on Assembled my first 3D printer 3 weeks ago:
Fellow Voron builder. I agree that getting reps in on other things made the build a lot easier. I found the mechanical portion of the build very straightforward thanks to things like flat pack furniture and Legos - it’s basically being able to follow well documented spacial instructions. Wiring wasn’t particularly difficult, but I’ve crimped things and built wiring harnesses before. The thing I was the most apprehensive about was getting the pi running and the initial tune, but everything is so well documented even that was pretty straightforward.
The Voron build is absolutely long, but it’s surprisingly approachable and well thought out. I guess that’s why there hasn’t been a revision in a while.
- Comment on God ****** dammit, here we go again 3 weeks ago:
Same, but I do have some level of worry regarding portability. My solution isn’t local or self hosted, as I was looking for easy and works across Linux/Windows/Mac/Android/iOS. I do not look forward to needing to change to a new password manager in the future, but given the way everything seems to be going it seems likely that I’ll have to at some point.
- Comment on Low cost continuous fiber 3D printer 3 weeks ago:
You’re going to have a heck of a baller Voron for 2.5k. My Voron, even with some CNC aluminum parts sprinkled in, was way less than that.

- Comment on Nvidia and TSMC produce the first Blackwell wafer made in the U.S. — chips still need to be shipped back to Taiwan to complete the final product 1 month ago:
Assembly is relatively straightforward, but sourcing all the components locally is likely getting harder and harder. Granted, for DoD contract reasons there’s likely a cottage industry that relies on government rules to keep things onshore. That’s part of the reason why we still have some made in the USA clothing.
This is worth a listen or a watch if you’re interested.
- Comment on #environmentalist 1 month ago:
Not sure how up to date this is, but synthetic fibers are the #1 source of micro plastics, followed by car tires and city dust. Car tires are absolutely a contributor and we should cut our reliance on personal transportation for more reasons than just micro plastics. In addition, we need to move away from polyester, nylon and a slew of other materials.
Most household furnishings used to be made of natural fibers. These days carpets, couch covers and filling, curtains, clothing, etc are often derived from a petrochemical. I suspect oil companies will continue to pivot into these areas to continue as we very slowly ween ourselves of gasoline.

- Comment on AI behavioral analysis on factory workers, every step is monitored including attention detection from facial expressions 1 month ago:
Ah, I see. It’s very true that a lot of plants have… older software setups that likely require a bit more of a human touch than should be necessary. I don’t work in a plant, but that’s basically been my career arc - “the poor humans have to hop between how many disconnected systems to accomplish what now? Let’s write some better software to address that.”
Using AI as a replacement to human glue seems reasonable if you have decent data to traverse. The “data” at my employer is often bespoke to each system, which results in a lot of gray matter mapping names and attributes across systems. Our IT org is working on rolling out glean, but so far it’s basically a better internal search than offering real insights.
- Comment on There was no need to ever improve upon THIS 1 month ago:
Agree with the addition of a low and high setting. I don’t care what the target cabin temp is, if I just got into my car after braving some crazy wind chill I want to be air fried for a bit.
- Comment on There was no need to ever improve upon THIS 1 month ago:
Used parts! Junkyards, eBay, whatever. Odds are you’ll be able to find a replacement unless the factory knob was super fragile or your vehicle is exceedingly rare.
If your vehicle is vaguely popular it’ll probably have a stl (think exported 3D shape) available. In that case I’ll print/mail you one assuming you’re in the US. If you’re not in the US hop over to !3DPrinting@lemmy.world and I’m sure someone will help you out.

- Comment on AI behavioral analysis on factory workers, every step is monitored including attention detection from facial expressions 1 month ago:
The amount of traceability in auto plants regarding what was put onto a vehicle would surprise a lot of folks. The capability to do this greatly predates AI and I’m not really sure what AI would add in the example you cited. Nearly any OE part with a barcode can be tied back to the vehicle it was originally installed on, what shift installed it, which other vehicles have a similar lot of parts, etc. Correlating this information with other basic record keeping, like which station installs the part and who was working at that time, makes it very easy to unearth trends. Plants have quality incentives, so there’s a strong motivation to identify areas for improvement.
In addition to quality, it turns out the small additional cost of all this data capture and storage quickly pays for itself in the case of a spill. Being able to say “this specific set of vehicles” can save a ton of money. That’s part of the reason why very small and targeted recalls have been becoming more common.

- Comment on Do deaf people know they have a deaf accent when speaking? 1 month ago:
Speaking and talking are colloquially used to describe people communicating in sign language. “I speak ASL”, “I talk ASL”, etc.
Definitions of the words speak and [talk](www.merriam-webster.com/dictionary/talk] cover non-verbal communication.
Speak: to express feelings by other than verbal means
Talk: to express or exchange ideas by means of spoken words or sign language
That said, I agree that OP was likely asking about spoken word.
- Comment on Anyone had any luck running Fusion 360 on Linux? 1 month ago:
Yes, this approach is called parametric design. FreeCAD struggled with the topological naming problem for quite some time, which basically means that internally named things, and references to them, can break under certain situations. Exposure to this problem increased as the thing getting molded became more complicated, which seemed maddening from a user’s perspective. It seems like it may have been fixed in the main branch somewhat recently, which I was not aware of. That’s good news.
- Comment on Anyone had any luck running Fusion 360 on Linux? 1 month ago:
I’ve dabbled in Linux in the past and spend the majority of my time popping between windows and mac os. I also spend a decent amount of time in powershell/terminal, but largely in the context of work.
I’m not against investing the time learn new things, but time is very scarse these days with two younger kids.
My modeling workflow is often iterative and fusion’s timeline makes it very easy to edit a feature from way back when and then propagate that change through all subsequent steps that reference that feature. You can also add entirely new features and then update the next step in the timeline to reference them. The last time I looked at alternatives this either wasn’t supported or was fickle, but based on some comments in this post that may have changed. I’ll have to give FreeCAD a try.
