  • 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.




  • Some of the arm based windows laptops, and even the newer x86 windows laptops, get pretty good battery life these days too. In my personal life, I have both an arm based MacBook and windows laptop. Both get similar battery life. I do wish there was an easy way to get Linux running on the windows laptop though.

    At work it’s usually all the corporate… bloat/security stuff that kills windows. I recently made the work switch to a MacBook and the difference is night and day.



  • Very nice! Welcome to the joys of designing and making functional parts. I suggest doing two things:

    1. Print, or buy, some radius gauges
    2. 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

  • 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.
