  • Maybe. People with more technical knowledge should understand that LLMs aren’t magic or sentient and have some severe limitations. Hell, I have been tinkering with ML and ANNs for a better part of 15 years or so and they can be extremely useful. (I am no expert and never indend to be.)

    It’s the marketing wank, scams, art theft and all the bullshit that pisses me off now. In that regard, I am squarely in the “Fuck AI” category. There is absolutely nothing phenomenal that has come of this recent bubble in the commercial space. AI generated images are mostly trash, articles are riddled with gross factual errors, phishing and other scams are more realistic (and maybe even more dynamic) now and public forums contain even more annoying bots. And the worst bit is that AI generated media, like music, is just a collection of averaged values with no originality.

    That bell curve represents something but it isn’t IQ.



  • I wouldn’t lean too much on their open source sales point. Yes, it’s open source, but there isn’t much more to that than a custom config for Klipper. The engineering diagrams on their GitHub are mainly just standard measurements for fans and such. They do include their own custom parts measurements, so that is nice.

    Cheap printers come with cheap parts and sub-par QA. I have heard great things about Sovol, but also very bad things about Sovol.

    The SV08 has been around long enough now so maybe most of the bugs are worked out. If Sovol didn’t solve some problems, the community likely did. It’s the nature of 3D printing communities, after all.

    If you want a cheap printer to be a workhorse, it needs to be disassembled completely and rebuilt after inspecting and replacing any critical parts with quality ones.

    These kinds of printers are just what they are. They work great until they don’t.


  • The weight test is typically super useful when you want to maximize extrusion rate. Even though it can be minimal, there is almost always a correlation between printed plastic weight and temperature.

    My thought here is that you are just within the minimum temperature range for that particular filament. If the hotend temp drops while it is printing, even just a hair, it’s binding the extruder enough to cause this artifact.

    My second thought is that the bed/hotend heaters are sagging the power of the entire system just enough to slow the steppers down a hair when they turn on. Testing this theory is not trivial and requires some EE knowledge and an oscilloscope. In the worst cases, the power supply would start to get really hot from hitting or exceedibg current limits. (If this actually is a deeper issue, I would check to make sure your kitty didn’t insert some rogue resistance into your electricals by way of chewing on the wires. The wires themselves might be getting warm in those spots, if that is the case.)


  • I would PID tune the hotend temperature. It doesn’t look like a mechanical fault like a stepper motor issue or belt.

    If you look at each layer, the striping is offset every layer somewhat consistantly and it looks like something is turning on and off on a regular interval, with the same pattern of “blips” in between. (The stripe seems to happen every x mm of printed line.)

    Plastics will behave and look different depending on what temperature they are printed at. There are typically glossy and matte sections in every print, actually. You may be hitting a temperature range at one of those texture-transiton points. A few degrees high, it may be translucent. A few degrees low, completely opaque. If that range is within your existing PID tune, that might contribute to the visuals here.

    Even with your micrometer, you are only measuring the widest layer over x layers. If your temperature is not stable, it could also contribute to some lines being thinner and more translucent.

    Testing extrusion rate by weight is a method that might be good here. Print 100mm of filament into a blob and weigh it. Change the temp a hair, print another blob and weigh that. Create a chart of 10-20 tests to see if there is a spot where extrusion is inconsistent. In your case, we want to replicate that striping, but for a weight test instead. The weight of the blob will change if hotend temperature is affecting extrusion rate. You need a good scale and preferably one that can weigh into hundredths of a gram. That precision is not required, but it helps.

    The reason I suggested a weight test is because your temps might be swinging between a temperature that is good and also just a hair too low.

    The hotend “heating response” might be laggy, is my guess, regardless of what may be causing it.

    Edit: The hotend temperature is kept constant in “bursts” of power. There might be a threshold where the hotend power is just full-on.

    Represented in a series of H’s and L’s (H for high, L for low), here is a pseudo-representation of what I see each layer and it matches a heating pattern of hotend but with a lower limit where its “full-on” heating:

    HHHHHHHHLLLLHHLLLLHHLLLLHHHHHHHHH…

    It’s not a perfect pattern in your case because a dozen different things contribute to final nozzle temperature.





  • Of course I do, but its very conditional in your case. For the record, I did miss that you had port forwarding enabled already and read your post as if you were just trying to connect to the open internet and see any traffic going to some rando servers. That would be a very different situation.

    How is the traffic proxied locally? Does the VPN client even allow inbound connections? Is a virtual interface configured for the VPN and is there an inbound port open?

    What makes this situation conditional is that there are several ways your VPN client could be configured and it is my guess that it is the bottleneck in this case. If you tried every address that you could find and saw nothing, chances are, there is no traffic to be seen. Any stateful firewall will drop an inbound SYN or traffic not related to an established connection.

    Your routing table may give some good clues as to where traffic is going as well. For example, the VPN client could be creating a local default gateway IP. Unless there is a split path configured, all traffic should be traversing that IP, regardless of what it is.

    So, can you elaborate more on the route your traffic is taking? Listening on 0.0.0.0 can sometimes work, but usually a specific interface needs to be defined as well. In some cases, tcpdump setting the interface to promiscuous mode can break things.

    Also, it’s a VPN. How traffic is getting routed in through the tunnel could be problematic. I have just been assuming that everything is fine up to the client you use and the computer sending traffic to inside your network is part of the VPN.


  • Ok, you are putting the cart a few steps before the horse here and put simply, you can’t just tap the entire Internet from behind your own Internet connection and “through” a VPN. (A VPN “tunnel” is a bit misleading on how traffic is seen in the wire, but that is still many more steps ahead.)

    Watching pcap is cool, but you need a fundamental understanding of networks and network protocols before you can actually see more than characters of the Matrix and understand what you are tapping into from the start.

    To kick off your own research path, start reading into the OSI Model, TCP vs UDP, traffic routing and subnetting. You need to understand where you need to be to see the traffic you want to see first.

    Unfortunately, I can’t begin to answer your question without some foundation in place first.






  • A bad trip isn’t fun even in the best of familiar environments. On the battlefield, it would lead to a very unpredictable situation in an already chaotic environment.

    Psychedelics are so different from person to person, it could be extremely inhumane for some, but the exact opposite for others. In other cases, you might actually be improving the reflexes and eyesight of your enemy. (For example, my visual acuity gets substantially better and it’s much easier for me to identify shapes against camouflage as an example.)

    If no combat action is planned against a drugged opponent, it becomes much more humane in that regard. That entire division would absolute out of commission but trying to capture them could become even more dangerous. It’s easier and cheaper to pin an enemy with a stream of bullets flying over their head, TBH.

    Sorry, I am basically thinking out loud.

    After thinking through a few scenarios regarding psychedelics, it would be pointless in most cases as the risks are higher than the rewards as its application would be extremely niche and would have to be combined with some other kind of deep psychological coercion. Otherwise, bullets and explosives are equally effective against someone who is drugged and someone who isn’t.



  • Yeah, it’s a common pattern with the “victim” crap. Same stuff I was just testing, actually. (Check my comment history with UM over the last day or so; re: define propaganda)

    Very nonsensical responses, no discussion and just absolute crap posts. If it is LLM assisted, it’s tuned to respond to people like they are hating on the acual article and UM. It’s an easy formula: post a shit article and just argue with everyone about anything while assuming they are commenting against the post.

    But I have met people just like that IRL and it usually comes with some serious mental disorders or poorly prescribed medications. (I am being extremely serious with that comment and no joke is intended, at all.) It’s probably for that person’s benefit to get kick-banned at all turns. Assuming it’s actually one real person, social media is not where they need to be spending their time.


  • I wouldn’t go so far as to say that. What I believe happens is that so much fake stuff is mixed with fact, the line between the two become blurred.

    In most processed food, there is an acceptable amount of insect bits that we almost always consume. So, when I am eating a sandwich, maybe 0.05% of it is insect. To me though, I don’t think of it as my daily dose of extra protein: it’s just my sandwich.

    The point of that colorful example was to explain how much worse the fake bits of Reddit actually are: Many people don’t usually know or even think about how much of it they actually consume. Lemmy has the same issues in some corners, but it’s much easier to identify.
