The 2 is a purge line, meant to clear any pressure in the nozzle and wipe it off before a print. It can be edited in your Start G-code on the printer settings tab > custom g-code on prusaslicer.

The 1 is a skirt, meant to get rid of any last few hanging bits of filament and start a clean print (sometimes the purge line doesn't get everything off the nozzle). It can also be used to gauge any last minute adjustments to your z offset. If the nozzle is too close or too far, you'll know before the print actually starts. I find that the skirt can be disabled if you're using a brim, since it's redundant at that point. Some who have fine tuned printers may opt not to use one at all without much issue. It isn't meant as any kind of draft shield as another person said - that's a separate setting. It's just a failsafe for the cleanest prints possible, avoiding hanging bits of filament, blobs from built up pressure, and incorrect z height. The first layer is the most important so everything that helps the first layer helps the rest.

This sounds eerily like the motto of conspiracy theorists when you start to ask too many questions.

Doubtful. The main reason I could see a 3D printer starting a fire is either thermal runaway, often caused by bad software (on cheap printers) or electrical issues. You can check your wiring and make sure that nothing looks loose and all of your cables are in good condition. You can also make sure that your printer firmware is up to date. It's a Prusa right? I think you should be safe from software failure in that case, as they're quality.

If you're really concerned about it, you can also move your power supply, and even your mainboard, outside of the enclosure by using longer cables. This would keep the majority of the electrical components away from the foam and heated box. From my position I don't see an issue, but that's my personal opinion -- not legally accountable information. I will say that Stefan on CNC Kitchen uses foam as well, to get rid of ringing in prints. If you decide to go through with it, just use common sense and check to see if anything is hot. You might also get some benefit out of looking into silent stepper motors/drivers and trying to make the printer itself quieter.

I was in my early 20s when I started. Wanted the calming effects of nicotine, was into other similar interests, and was dating someone who also got into it. He was actually the second vaper I'd dated, so you could say it took me a while to be interested.

I'd had a couple cigs before but I never considered myself a smoker and didn't take to it. Vaping became a huuuge hobby for me. Learning about different mods, building your own coils, DIY e-juice, etc. I was vaping all day, all the time, pretty much as soon as I woke up (at the lowest amount possible though). It was a nice flavor and chemical pick me up when I was on edge. Sort of like a physical distraction. I vaped for 5 or so years. The lasting effects I've noticed are that sometimes I miss it. That's it. It was pretty hard to quit, mostly because I didn't want to. I had a lot of resistance, because it became a passion for me. But nicotine regulations started to suck, and that same partner quit as well. I got really sick with a flu and didn't vape during it. Then, I didn't start again after I got better. I had dreams about it, and it took a bit for me to want to move on.

The thing is, though, I don't feel any different now than when I was vaping constantly. It doesn't improve your life that much. It'd be great if it could be an occasional thing, like alcohol or dessert is, but it's hard to not do it all the time if you're doing it at all. And you get to an equilibrium where it just doesn't feel that strong. Hence the constant clouds.

The most annoying part about it is that it becomes like a security blanket. You have to take it everywhere. Forget it for work? Guess you'll just be late today. Have to sit for a movie? Man it sucks not to vape inside. Flying for hours? What a nightmare, can't wait to land and go outside.

It was annoying to not feel myself if I ever decided to leave my vape behind. And blowing clouds out of my car was great, but it sucked having to wipe down my car windshield all the time due to the glycerin condensation. Same with inside -- no smoke on the walls, but the glycerine would hang around and I'd have to run an air purifier. I'd often worry about the vapor leaving slight residue all over my apartment, belongings, monitors, PC internals and such.

Overall, it was great for a while as it was something I got really into, but it was also a lot of money and stress over something that didn't really benefit my life the way other hobbies still continue to do. Much better to be a free person unattached from adult security blankets. 😎

I was just thinking about this the other day. It's weird how Google has become so unusable due to its own practices that it seems to be giving up on being a search engine. I've been getting spam pop-ups lately on mobile search asking me to use AI. Of course people will wanna use it, they can't find their answers normally anymore. You search for something and it'll show you something completely unrelated because it's trying to be "helpful" and corral you towards buying shit, and it doesn't even do a good job at that. Heaven forbid you start to look past the first 3 pages.. I don't have a clue how these websites in the search results are maintained when they're filled solely with spam and nonsensical gibberish. I'm totally with you. We used to actually see communities around and now it seems like they've fallen into the dark web, unfindable except by means of knowing someone who knows someone or, frustratingly, reddit. Paradoxically, it's like the random AI-generated hash from the dark web is now here clogging up the tubes. I feel like everyone else came along and started dumping trash everywhere because we didn't put up any signs or make any rules not to litter.

Man, we really need better labor laws.

Technically correct is the best kind of correct.

Speaking as someone that started with little experience, I love Adam Ragusea and Pro Home Cooks. Both explain things you never thought to ask about cooking and concepts that you can apply across lots of different dishes. I've learned things that I still continue to think about long after watching whenever I'm making up some food :)

Sounds like brain fog. Speaking as a fellow sufferer of anxiety (health anxiety included), I know how it is see something that seems wrong with you and try to pin a cause onto it. Are you being social? Keeping up with sleep, food, exercise? I know those are overstated but it sounds like you're having some brain fog. The more you focus in on the fog the more it may seem pronounced, as brain fog is highly influenced by stress. I've suffered from some myself and have felt kind of tuned out for a while. A large part of it for me has been from the shock of different life changes and the endless stress of work and relationships. The fog in that situation doesn't get a chance to subside because the body is trying to get through sustained stress with little damage.

It could also be from imbalances of vitamins like vitamin d or iron. Just to be clear, I highly doubt it was from the burning cable. It's definitely not good for you, but people smoke cigarettes and breathe road fumes for decades without losing the mental capacity you're describing here. Funky stuff happens when we look back on our past selves too, I feel like it's hard to make a fair comparison to yourself at any prior point when you factor in a lot of things that happen in-between. I don't doubt what you've been experiencing though. Sounds crappy. I hope you give yourself a chance to consider all of the possibilities and be easier on yourself for not functioning at 100% right now -- it doesn't mean it's forever or that it means something big, it could just be your capacity right now.

The number one thing I've heard from avoidant people is that perfectly human emotions, albeit perhaps unfitting for the situation, are "clingy" or "too much." They don't know how to ask for things like space and own their own needs. It's much easier to instead blame their inner turmoil and resistance on the relationship by singling out that one thing they think is wrong with it. That way they don't have to be vulnerable and admit they're imperfect too. I'm sure you might know all of this anyway, but just a reminder that it's okay and healthy to be a lil clingy and worried. Not your fault.

I had something similar happen a few years back. I had matched on tinder with someone from a different state that I actually met years ago in high school. I hadn't really been interested in him that way back then, but we reconnected and it was intense. We talked everyday and our birthdays both fell on the same weekend, so I went down there to visit him and celebrate together. Only a couple days in, he told me one night that he was falling in love with me. We built a pillow fort, partied, and went hiking together. I was absolutely smitten and so excited to start something new.

I ended up putting off the rest of my road trip to stay longer with him. However, when I finally did leave, I was driving through miles of desert when he texted me and said that he actually didn't see anything happening between us. He said that he wanted someone who knew when to "leave him the f alone" and wasn't looking for someone who wanted something super deep, but more so just companionship. It felt like such a rejection of who I was and I was gutted. I felt like it was somehow my fault. Since I didn't have signal, it was a rough drive alone with my thoughts.

Towards the end of the night, I ended up texting with a friend about it while I camped out (still on my road trip). It sucked at the time but looking back, he was kind of a prick. He had no shame about leading me on and he picked on me for little things while I was visiting him.

It's usually a bad sign when things feel so intense right off the bat. It's only easy for this guy to leave because he really doesn't know you well enough to know what he's missing out on. It might feel like you missed some chance, but it isn't your fault that this happened and there wasn't more you could do. Be gentle with yourself. ❤️ This guy wasn't honest with himself or with you about his feelings, and he ended up hurting you for it. It's clear to me that he likely isn't mature enough for you. Remind yourself that you were willing to go the distance, right? You did everything you could have. You want someone who will go the distance with you and follow you to the ends of the earth, and tbh, it's much more likely something to do with him, not you. Meaning that even if the distance wasn't an issue, you don't know if it would work either.

And you don't have to get over it right away. It's okay to just kind of drag through the days for a bit. But keep socializing, because other nice (and even attractive!) people will remind you that you still have something left and you're worth kindness from others. And do things for yourself. When I get lost after heartbreak, what has helped a lot is going for walks or hikes, sometimes on trails where the signal is iffy (so I don't expect a surprise text), with an audiobook or some music. I really wish you the most kindness. Feel free to shoot me a message if you need any extra support, I've been there.

I'm proud of you!! That's huge. You should give yourself a well-deserved pat on the back. Verifiable progress and it's only up from here, keep it up :)
