  • 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.


  • 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.


  • 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.


  • So much the same. In this market I would rather stick around with the devil I know beii have a good reputation and network. I don’t want to be the new person somewhere else should things go sideways. Grated, I am very much on the chopping block at my current employer given the waves of layoffs and “performance frings” that have been happening…





  • I got curious and will attempt some math and duckduckgoing.

    A forest can remove between 4.5 and 40.7 tons of Carbon Dioxide per year per hectare during the first 20 years of tree growth. Sauce

    Humanity is currently generating around 40 billion tons of CO2 per year. Sauce

    So now some simple math: it would take between 1 billion and 10 billion hectares of forests, depending on their maturity, to keep up. 100 hectare = 1 km2 sauce, so this means 10 to 100 million km2 of forests.

    Earth’s total surface area is 510 million km2. sauce.

    Of that, here’s a quick breakdown:

    Sauce

    So 10ish percent of the 510 million km2 of land on earth, or around 5.1 million km2 is a good candidate for tree planting. That’s not enough if we want to sequester all the carbon produced by humanity. Without getting to net zero global warming will continue. The best we can do is slow it down. More disconcertingly, our appetite for energy is only increasing. The good news is that we’re really starting to see large scale wind and farm operations ramping up, but there are still a lot of power plants scheduled to come online in the next two decades.







  • 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.



  • 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.





  • 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.
