- 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 day 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 day 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.

I still have a sweet spot for canned corn, especially creamed, as well as canned green beans.
- Comment on AI behavioral analysis on factory workers, every step is monitored including attention detection from facial expressions 1 day 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.

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 day 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.

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.

Thanks! A VM is a totally viable option.
- Comment on Do deaf people know they have a deaf accent when speaking? 1 week 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? 3 weeks 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? 3 weeks 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.
- Comment on Anyone had any luck running Fusion 360 on Linux? 3 weeks ago:
Thanks, I’ll have to give it a try
- Comment on Anyone had any luck running Fusion 360 on Linux? 3 weeks ago:
Thanks for the information. I think I’ll give Linux a go on a spare SSD and can treat this as my fallback plan.
- Comment on Anyone had any luck running Fusion 360 on Linux? 3 weeks ago:
Oh, I know. I am familiar with the fusion workflow and it generally just works - even when you mess with a feature way earlier in your timeline.
I model some vaguely complex things and find that I often fiddle with things. From the last I looked into it, OSS CAD didn’t handle this very well.
- Comment on Anyone had any luck running Fusion 360 on Linux? 3 weeks ago:
The second link to this repo, thanks!
When you say it breaks every few months does that mean that fusion does its usual update thing as-per-normal and then just nopes out one day?
- Comment on Anyone had any luck running Fusion 360 on Linux? 3 weeks ago:
I haven’t looked into this at all, but wasn’t Microsoft threatening to block updates if your system doesn’t meet the requirements?
- Comment on Anyone had any luck running Fusion 360 on Linux? 3 weeks ago:
Sweet, thanks!
- Comment on Anyone had any luck running Fusion 360 on Linux? 3 weeks ago:
At this point I want to give Linux an earnest go on this box. I bought a second SSD and will just unplug the windows drive for a while.
I am curious if fusion will support LTSC and/of whatever version of 11 they call out.
- Comment on Anyone had any luck running Fusion 360 on Linux? 3 weeks ago:
Fusion said it will stop working. It’s normally a licensed product, although home users can get it for free. I suspect they have some kind of authentication mechanism built in and could prevent it from working if desired.

I built a cardboard enclosure around my poor old i3 clone to get my Voron parts printed. It was a bit janky, but it worked and I can now say that my i3 clone can totally print ASA.
But agree that not having an existing printer at all does make for a potentially harder build, especially as figuring out all the parts you’ll actually need ahead of time can be somewhat challenging.

I have a 350mm 2.4 and chose it specifically because I tend to make bigger things. The flying gantary is super cool looking, but it does come with a downside: all your tool head cables, if you switch to an umbilical instead of the cable chain, and your filament run have to accommodate the gantary getting ever higher if you have a tall print. It’s not an unsolvable problem, but it’s also a problem that doesn’t exist if the bed is the thing that moves.
One of the pluses of a Voron is that it’s enclosed, which means that you can print ASA/ABS for pretty rugged prints. This means needing to preheat the chamber - especially for larger prints. On a big printer this can take quite some time, and also requires some insulation, but there really isn’t a way around it without doing something silly like putting a heater other than the bed in the printer. Fortunately, if you’re printing a smaller part you don’t have to worry about preheating.
A three final thought on a big prints:
- when prints get big enough basically everything will warp without a heated chamber. This is especially true for ASA and ABS but is also true for PETG. I haven’t tried a big PLA print, but I imagine once they pass a certain size they’ll warp too
- if you want fast prints you should look at wide extrusions and thicker layers. I run a 0.6mm nozzle basically all the time with 0.8mm or 0.9mm extrusion widths and 0.3mm layers. It’s all about how quickly you can lay down plastic in mm^3. This will make your bottleneck your hot end
- even with chunkier layers big prints can take a long time. I printed a speaker and it took something like 20 hours for the biggest body and it was “only” around 280mm in circumference and 270mm or so tall. Granted, if I could have fit this on my i3 clone it would have probably taken 5x longer due to a much weaker hot end.
There are bigger printers out there, but between warping and print time I don’t know that I would personally want one. For the rare times when 350mm isn’t enough I can always split parts, but that hasn’t been an issue so far.
- Comment on What are your favorite open source 3D printers? 5 weeks ago:
Most Voron folks will usually suggest building as close to stock as you can initially and going from there. LDO’s kits modify the stock BOM quite a bit, which can make for a more challenging build. Buying from someone like West 3D. Formbot kits use to stick to the stock BOM fairly well too.
As for support, there’s an active discord server and forum you can use to get help. They also have a print it forward program where you’re matched with a Voron owner who will print your functional parts for the cost of material.
- Comment on What are your favorite open source 3D printers? 1 month ago:
3 hours in and no one’s brought up VoronDesign? You can’t buy their priners or parts directly, you either have to self source or buy some variant or “BOM in a box” from a third party. I’ve had mine for two (three?) years and although the build was long it was very well documented, via a 240+ page lego-like build manual. It’s a great printer and community.
- Comment on Adhered so hard it delaminated the glass. 1 month ago:
Sorry for the delayed reply. No, too warm won’t cause warping. However, the hold side of your hot end will at best be ambient temperature. If it gets too warm you can clog your nozzle.
My view is “if the chamber doesn’t need to be hotter why make it hotter?”.
If you were printing ASA/ABS you want your chamber to go basically as hot as you can get it though - especially if you’re printing something big.

- Comment on Adhered so hard it delaminated the glass. 1 month ago:
Lifting on the corners, especially if this was a bed sized print, was probably due to warping. It stinks that it took out your bed, but warping probably wasn’t the cause there.
My main printer these days is enclosed. When I print PETG on it I’ll pop the lid open because PETG doesn’t like to be too warm.
- Comment on Adhered so hard it delaminated the glass. 1 month ago:
That looks like somewhat similar to an ultrabase bed. I have had one of those on my i3 clone for years and years. I’ve also printed a reasonable amount of PETG on it. Was the print and/or bed warm when you tried to pull it off? Prints detach much better when cool.
- Comment on Downsize Ender 5 plus? 1 month ago:
The ender 5 isn’t a bed slinger so it should be relatively compact for its print volume. You can certainly get a smaller printer. You can do this by getting a more compact printer and/or sacrificing build volume. If you want compact you’re probably going to want a coreXY
For example:
- your ender 5 pro is 552mm x 485mm x 510mm and has a build volume of 220mm x 220mm x 300
- a Prusa i3 mk3 is 500mm x 550mm x 400mm and has a build volume of 210mm^3^ (the bedslinger is indeed bigger)
- a 300mm^3^ Voron 2.4 is 460mm x 460mm x 480mm and has, well, a 300mm^3^ build volume. They also have a 250mm version that will probably save another 50mm in every dimension
- a Prusa mini is 380mm × 330mm × 380mm and has a build volume of 180mm ^3^
- a Voron 0.2 is 230mm x 230mm x 250mm and has a build volume of 120mm^3^
- I gave up on finding dimensions on the salad fork, but it’s probably going to be even smaller than the v0 due to using 15x15 extrusions instead of 20x20
