  • Yeah, I made nearly that mistake. Twice, actually. First with a monoprice, then a creality. I probably have more money in upgrades on my CR10s than I have in the purchase, and I still haven’t upgraded the board. I keep thinking I’ll fix it but I’ve resolved to strip a couple of parts and throw it away. My Prusa XL preorder came last month. I made one update to it (for better TPU performance), and printed one QoL add-on (nozzle wipers). That’s it. I’m done. It prints like a dream, multi-material supports are indistinguishable from magic, and even swapping nozzles is fairly quick and easy. Now I’m (almost) exclusively printing things for my other hobbies rather than worrying that something on my CR10s will fail or need re-tuning.



  • Me: Should I buy a prebuilt 3D printer?

    Reddit 3D printing sub: Oh, heck no. I put mine together for $18.22 plus some spare parts from seven printers I got of craigslist for $1 from some widow. Only took me three weekends to do it, plus a couple hundred hours to update the firmware to match the parts and troubleshoot it.

    Me: Uh, so does it print better than the one I could just buy?

    Reddit: Well, I’m still tuning it for all my filaments. I’ve been through about 40kg, and I’ve got a trashcan full of benchys though. The last few have been pretty good.












  • the US becoming a major oil and gas exporter

    This is a common misconception - we’re already the oil producing gorilla. Oil, both unrefined and refined, have been the top exports of the US for years now - well over a decade. We are the largest global producer of oil - by a huge margin - and have been for years. In 2022 we were almost 19% of the global supply - producing 50% more than each #2 Saudi Arabia and #3 Russia, and more than the next 4 countries combined.

    The conservatives in the US like to say that we have to drill in an attempt to become energy independent, but we send much of our product to higher paying markets outside of our own border. Our only imbalance is in the mix of refinery capability and domestic supply type (light/heavy/sweet).




  • Lots of advice here, some of it good, some of it questionable.

    Two things I’ll amplify from other comments: there’s a reason your therapist missed. It’s could be anything from messing up in their calendar app to a pet or a family member being injured it passing unexpectedly. This falls into the “shit happens” category. You’re allowed to be angry, upset, disappointed, or any combination - your time was wasted. There are generally two outcomes - 1) the miss was unintentional or unavoidable or 2) the therapist is unreliable. Until you find out that it’s case 2, recognize that a couple of wasted hours - in the course of your life- is small potatoes (perspective).

    Another is the concept of “agency”. There are things you can affect in your life, in your relationships, and in the world. There are things you cannot. Nobody can force you to allow yourself to ignore the latter. They will always get under your skin. However, if you find yourself dwelling on those items, try and take a step back and identify things in your life you control or which you can alter/adjust. Finding those areas where you have agency allows you to impart your will, to be a positive force in your life trajectory.

    I won’t even begin to tell you this is easy. It is a process and a way of interacting. Here’s an example - recognize your disappointment with your therapist but take the initiative to reschedule. Taking it a step further, the day before your next meeting, confirm the appointment. It can be a text or email - simple, low contact. If you don’t get a response, escalate near the end if the work day (or first thing the morning of the appointment) with a call. These are things you can do to manage your therapist and your collective schedules. Most professionals (I am one fwiw) will not be offended in the least with good (but not excessive) communication. If they are, or if the therapist still flakes out on you - well, we’re back to case (2) above and you’re on the troublesome path of finding a new / another therapist. BUT - you’ve done all you can in your power to make this a success. Recognize your initiative as a positive, personal attribute you will continue to leverage in your life.

    I wish you the best!


  • This is the internet so take this with a grain of salt. I work in a life safety field and the last 50 years of research has been to shift the evaluation of safety from an arbitrary value for safety to a statistical basis - all in the name of efficiency (cost, material, environmental - pick you’re cause, they all have a voice). There is generally no perfectly safe condition, only a poly at which the number of standard deviations from the norm makes failure so unlikely as to be nearly impossible. We have classes of prevention and imposed conditions and there are under the intersection of (failure in prevention)x(exceptional imposed danger) are dead people, or at least loss of property.

    Shifting the freezer set point is moving the prevention curve. The number may be small, but it’s still finite. The question the actuaries will ask is if the economic value of 19MT is worth an increase in probability for the sickness or death of X people. I’m merely arguing that the value, to me personally, is not sufficient.
