Cool, thanks! I will give it a try when I print the mirrored version of this thing.
- Comment on maybe maybe maybe (larger ASA print in progress) 1 day ago:
That’s an interesting suggestion. What failure mode have you found that to help with? I am under the impression that the temperature gradiant between the bottom of the print and the top of the print, combined with thermal expansion, is the reason why printed parts warp. ABS/ASA expand/contract twice as much as PLA.

Vent and filter! I have one of these under the bed and the printer is vented.

- Comment on You won: Microsoft is walking back Windows 11’s AI overload — scaling down Copilot and rethinking Recall in a major shift 3 days ago:
As someone with a foot in Windows and Mac, they both suck for different reasons and you’re trading pain in one for pain in the other.
Windows sucks because of all the stupid one drive and AI garbage. No, I don’t want my desktop and tons of other directories in one drive, stop asking me. The constant migration of settings out of control panel is maddening. Windows 10 end of life is fine, but cutting off older PCs from windows 11 for “reasons” was an absolutely horrible choice.
Mac is fine if you do super basic computing, but if you want to do much of anything it’s very annoying out of the box. Window management is annoying unless you get an app like magnet, the ribbon can’t be displayed on dual monitors and there’s no way of fixing the primary monitor, keyboard shortcuts are inconsistent across applications like command delete and keyboard shortcuts in general suck (command + shift + 3-5), the OS greatly dislikes network storage, etc etc. Macs were somewhat isolated from marketing needing a “new” OS every year until recently. Now they’re in the change for the sake of things to list on the new OS page trap.
Linux isn’t without fault, but my experience has been much more pleasant.

This is a very easy to follow guide that walks you through everything but temperature towers in a sequential order: ellis3dp.com/Print-Tuning-Guide/
- Comment on Help! What is wrong? 1 week ago:
Late to the party, but…
How well tuned is your printer? This whole print is a torture test with lots of retractions and thin walls. For things to go well you will have needed to dial in flow rate, print temperature, cooling, and retraction. As someone else said, if the nozzle catches on an unsupported lever arm (aka one of the vertical pieces before a horizontal bridge has been completed) it can/will break it off.
If your printer has never pulled off this type of print before I suggest running through some basic tuning tests before worrying about potentially wet filament unless you live in a very humid environment. I live in a temperate climate where it doesn’t generally get that humid. My printer and filament live in my basement, which has a dehumidifier in it. I’ve never dried a role of filament and I leave spools unfinished for 6+ months. That’s not to say that you never should dry your filament or that doing so won’t improve print quality. I’m just trying to say that I have not experienced a higher rate of print failure with older spools.
- Comment on Does Prusas textured sheet...work at all? 2 weeks ago:
Seems like great success? If so, great. The only things about your routine I would change is to not submerge, not because that’s bad but because who wants to obsess over cleaning their sink first, and use paper towels to dry. You want to make sure no films are transferred to the bed.
- Comment on Hundreds of Millions of Audio Devices Need a Patch to Prevent Wireless Hacking and Tracking 2 weeks ago:
More work location flexibility is certainly something I would appreciate. The company I work for is hybrid and with the looming economy mess I’ve been putting off job hunting. I would much rather be somewhere with a network should things go sideways.
- Comment on What next, power supply shortages? 2 weeks ago:
I bought a used workstation (xenon, ecc memory) pre-covid hit. I swapped the processor with the highest spec one that would fit the socket (thanks for changing sockets so frequently intel… not) and 64 GB ecc momory. Both were cheap because they were used. About 6 months before the GPU crazyness I bought a used 1070 TI for around $200. Upgrading the GPU a few years later was out of the question and now upgrading the whole thing is out of the question.
Due to the processor age I’m just going to install Linux on it and cozy into my older game library. Gaming time is pretty limited these days anyway due to having kids and these days I’m doing most of my gaming on a handheld.

- Comment on Wine 11 runs Windows apps in Linux and macOS better than ever 2 weeks ago:
White collar professionals who spend their days developing and deploying software or working on compute infrastructure? Sure, some of them have been on Linux for decades. Although many big corpos love Windows and Microsoft products, so at best you’re going to have a foot in both worlds if you work at one of these companies.
Some admin jobs that don’t require bespoke software (ie very little beyond say an office suite) have started making the jump recently to save $$.
Basically every other white professional that needs to work on a computer with industry specific software like people in medical, engineers, business? Odds are they use windows since the software they use for their job is probably only built for Windows and maybe Mac if they’re lucky. Very few employers are going to mass deploy Linux to run applications via Wine. These employers have support contracts for the major software products their employees use and they won’t get support if they’re not running software on its native OS.
- Comment on Priming and sealing a painted print 3 weeks ago:
This is less about 3D printing and more about “what material will adhear to the layer before it?” For example, using both water and oil based products is generally not a great idea. If want to use both then a layer of sealer will help.
How you want to apply the paint (eg air brush vs bristle brush) will greatly impact which paints and finishes you can choose. It will also greatly impact your final finish/look.
In most cases no need to “seal” paint. In fact, depending on the type of paint it might be a sealer itself. A sealer can protect the paint below it from say UV light or water. A sealer can help you achieve a higher gloss finish. However, the paint itself might already be durable, UV stable, and have the sheen you want.
The question isn’t which store sells better paint, it’s what kind of paint do you want to use? After that the choice of store is largely a question of who carries that type of paint with an added wrinkle or brand variation. For example, you’re not going to find miniature airbrush paint at a big box store and you’re probably not going to find automotive paint at either.
- Comment on Selfhosted coding assistant? 3 weeks ago:
Straight up vibe coding is a horrible idea, but I’ll happily take tools to reduce mundane tasks.
The project I’m currently working on leans on Temporal for durable execution. We define the activities and workflows in protobufs and utilize codegen for all the boring boiler plate stuff. The project hasa number of http endpoints that are again defined in protos, along with their inputs and outputs. Again, lots of code gen. Is code gen making me less creative or degrading my skills? I don’t think so. It sure makes the output more consistent and reduces the opportunity for errors.
If I engage gen AI during development, which isn’t very often, my prompts are very targeted and the scope is narrow. However, I’ve found that gen AI is great for writing and modifying tests and with a little prompting you can get pretty solid unit test coverage for a verity of different scenarios. In the case of the software I write at work the creativity is in the actual code and the unit tests are often pretty repetitive (happy path, bad input 1…n, no result, mock an error at this step, etc). Once you know how to do that there’s no reason not to offload it IMO.
- Comment on Bose open-sources its SoundTouch home theater smart speakers ahead of end-of-life 4 weeks ago:
For passive, and even now some active loudspeakers, very much so.
Links for passives: sites.google.com/site/undefinition/diy www.zaphaudio.com www.madisoundspeakerstore.com/speaker-kits/ (etc)
Active speakers are usually things like this and use commercially available parts with commercial software. But if you want you can build a DIY DSP and DAC and DIY amplifier. Note that there are tons of other designs for both available.
The DIY audio community is very vibrant. [There](www.diyaudio.com/community/] are tons and tons of forums collaboratively iterating. You can build [DIY headpy](github.com/ploopyco/headphones] and DIY headphone amplifiers. Hell, you can even build [DIY speaker drivers].
Anything I missed was not an intentional omission, lol.
- Comment on Switching out most of the toolhead stack on a Voron 2.4, anybody know if these options work together? 5 weeks ago:
A quick search turned up an “official” CNC mount for cartographer and stealth burner. There are also instructions covering another mount, but I didn’t spend much time looking at them.
If you’re comfortable with CAD it shouldn’t be hard to model a mount that uses the klicky attachment points on the stock SB carriage. I found an existing model that looks like it does exactly this.
- Comment on Switching out most of the toolhead stack on a Voron 2.4, anybody know if these options work together? 5 weeks ago:
Not to ask the dumb question, but if your main pain point is tap why not just swap tap for cartographer or even klicky? Klicky, combined with Klipper Z Calibration has been pretty reliable on my build and gives me a very consistent first layer.
- Comment on Condoms and contraceptives to become more expensive in China as Beijing accelerates push to lift birth rate 2 months 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 2 months 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 2 months 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 2 months ago:
Did it look more solid or did print quality basically remain the same?
- Comment on I'm doing something wrong; can't print this PETG 2 months ago:
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 2 months 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 2 months 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’ 2 months 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 months 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 months 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? 2 months 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? 2 months 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 2 months 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.
