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.

No.

I think the concept of stars literally hitting each other is rather moot

In many ways, I agree with you. I was simply trying to paint a picture of how much space is in between stars. Visualizing the scale and distances of the universe can be extremely difficult, so I opened with that to help explain why the chances of collision or significant interaction were low. However, given amount of time involved, a significant interaction has probably happened before and may happen again. (Visualizing space and time is hard for me, actually.) With that, I should cap my improbability to “within the time that humanity has ever existed, or will ever exist”.

However, you did get me thinking about disruption on a much larger scale, far beyond the oort cloud. Could a cluster of black holes disrupt our orbit around the galaxy center significantly? Locally, even something of considerable size passing through our solar system can disrupt our own solar orbit, but may only measurable after thousands of years.

We are in a relatively quiet spot in our galaxy now from my own understanding, but if something was able to bump us (and hundreds of thousands of other stars) just a hair, it might have dire consequences in a few million years. (I wouldn’t imagine that we would notice getting kicked out of our own galaxy completely though. Dunno.)

Tiny chance of that. When, and if, the the Milky Way collides with Andromeda, the chances are still astronomical that any stars actually collide at first. Shit might get really weird as the SMBHs start to come together and the centers of each galaxy eventually begin to merge, though.

That example was about how far things are from each other in our galaxy. The biggest problem is how much gravity is in play and how fast objects in the universe travel. An object like a planet and a blackhole only have a very narrow space to actually collide or have the planet get locked in orbit or a death spiral around a black hole. It’s more likely a planet would get accelerated and spun out on a very different trajectory when they get close together.

So, your hope of us colliding with a blackhole is very unlikely. It’s probably more likely we would get shifted into a different orbit around the sun or get kicked out of the solar system completely. If you were just wishing for hell and chaos, you would still get your wish in that regard.

Still, if we could survive the extremely deadly area around a blackhole, it would be kinda neat to fall into one. In theory, time and space is so wonky, we should be able to catch a glimpse of the end of the universe before we get crushed into an infinite point. Neat.

Have you ever considered not paying attention to what people say back?

I have never considered doing that at all. It happens naturally in the middle of conversations.

Goodbye.

It is said, bitch! Don’t you listen?

I have spoken.

4.3 people are now learning Chinese.

Having v-cache on one CCD is not an issue. It seems most of the scheduler issues have been fixed and that was just software. It would be nice to have v-cache on both, but it actually adds more complexity.

This goes in the “shit UM would say” bucket.

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.

It’s showing up on Lemmy fine. However, I think I need to create a post filter for hashtags or cross-site posts somehow.

#If #I #wanted #to #see #shortform #socialmedia #posts #i #would #use #the #proper #site #for #it … #testicles #wwjd #nascar

You were allowed to skip every Kazon episode except the one where they try to reverse engineer a replicator. (That might help on the next rewatch.)

Its probably more accurate for me to say that I think there is a gradient of people between instances. Using politics as an example, and without details, people seem to gravitate to instances where they are with like-minded folk. Combine that with local or global filter preferences, and echo chambers start to form on a per-instance basis. Communities of higher interest will likely be on the users home instance, after all.

But yeah, I am fairly sure most of us browse /all and see content from all over Lemmy. We still mix and mingle, but are still lightly bound by our own filter preferences. See above paragraph.)

(I am not trying to dictate hard rules of behavior, btw. Lemmy is too diverse for anything definitive.)

Personally, I try to only block specific communities and not entire instances. That has seemed to keep my personal feeds fairly open.

Lemmy is a perfect replacement for Reddit because it’s not Reddit. The feed was curated and not as organic as the voting system made it seem. As time passed, it became more of an algorithmic engine for dopamine extraction. Sure, I had some great times there, but times change.

Lemmy is not a perfect copy, but it is a healthier replacement in some ways. Separate instances do amplify echo chambers, but, they mildly serve to keep different groups separated. Some personality types are just not compatible and that is OK. We still have common spaces and can still be civil, mostly.

For now, there isn’t as much room here for business. Sure, we have plenty of porn but this platform isn’t as easy to exploit for money as Reddit was. No centralized advertising structure is awesome, IMHO. (Some clients still leverage ads, but I don’t use them.)

Is SPM typically considered continuous production without slowdowns forever, or, is there some unwritten rule about needing to maintain +1000 for a specific amount of time?

I can spike to 700 SPM at times, but it only lasts for a minute or two until a resource or two gets completely sucked dry. (Until I get better production, I just pace my research and buffer enough resources to keep research at 100% for a bit.)

Jews control the space lasers and weather manipulation weapons, after all.
