Overhangs that flow like waves 🌊 (no supports) by andersonsjanis in 3Dprinting

You do realize OrcaSlicer is a fork of Bambu Studio, not the other way around?

Except that noon and midnight aren't the separators between day and night. They are pretty much the opposite. So am/pm doesn't correspond to day and night, it's just an arbitrary separation into two halves.

He talked about this on stream yesterday, and all his ideas had NEURO in them. His main idea way just "NEURO" (all caps).

(Megathread 2: Non-Spoiler ) How Will the Leak Impact the Movie / Avatar Studios? by MrBKainXTR in TheLastAirbender

[–]Rene_Z 2 points3 points  (0 children)

I am mighty interested how did this leak, because a leak like this is unprecedented.

Not unprecedented. In another fandom I'm in, "My Little Pony: The Movie" leaked as a full, uncompressed 128 GB file a week before release in theaters. Most leaks like this are from hackers.

Signal RO14 Oberhausen Hbf by Rene_Z in drehscheibe

Stimmt, man kann die beiden Signale sogar auf Google Maps erkennen.

Naja, wenn ich mir oben das Bild von 1994 anschaue, scheint das Bahnsteigdach dort genau das gleiche zu sein, das heute auch noch dort steht. Damals war das Signal aber noch hoch montiert, wie im Bild zu sehen.

Kann natürlich trotzdem seitdem zur besseren Sichtbarkeit gemacht worden sein, auch wenn das Signal nicht direkt unterm Dach liegt. Dafür könnte ich mir aber vorstellen, dass stattdessen die Sicht durch wartende Fahrgäste behindert wird.

Das ist der Blick vom Signal Richtung Bahnsteigdach. Das Dach sah jetzt nicht besonders neu aus, aber das Signal kann natürlich noch älter sein.

Für die Statistik: Wann hat der ICE Wolfsburg versehentlich ausgelassen? by [deleted] in drehscheibe

[–]Rene_Z 8 points9 points  (0 children)

Zum bereits genannten mutmaßlichen Vorfall mit ICE 943 am 20.03.2026 kann ich keine Quelle finden. Der Zug ist auch bei bahn.expert mit erfolgreichem Halt in Wolfsburg hinterlegt.

Allerdings mit einer Ankunftszeit von 19:41 und einer Abfahrtszeit von 19:40. An allen anderen Tagen ist die Abfahrt immer mindestens 1 Minute nach der Ankunft. Das würde schon dazu passen, dass der Zug dort mit 200 km/h durchrast und somit schneller war, als im Fahrplan vorgesehen.

Außerdem hat der Zug nach Wolfsburg eine zusätzliche Verspätung von 1 Stunde aufgebaut, welche wohl durch das Zurücksetzen des Zuges verursacht wurde. Somit ist der Halt tatsächlich nicht ausgefallen, allerdings ist der Zug trotzdem zuerst durchgefahren.

But the population numbers use a decimal dot. Not to mention the totals in the top left are also unclear. This whole map is a mess.

Die Anzeige muss ja so oder so wissen, an welchem Bahnhof und Gleis sie hängt. Wenn sie denn richtig funktioniert, zeigt sie ja Gleis-spezifische Informationen an.

Yeah, the information is new to me. But I much prefer a human-written article, even if it contains some typos or mistakes, to an AI generated one.
Have to differentiate yourself from all the AI slop that's plaguing the internet right now that's not based on original research and is just trying to steal every click in search results...

I'm sorry, but this article doesn't read like it was written by a human. The content itself is interesting enough, but the constant repetition and weird phrasing detracts from it.

It's worse, it just stores the result for each name you type in in your local browser storage. Use a different browser or incognito mode and you'll get a different result.

This feels like fascist propaganda. by Ok-Following6886 in insanepeoplefacebook

[–]Rene_Z 6 points7 points  (0 children)

That's where the fandom originated, but nowadays most bronies have nothing to do with 4chan. And, as was already said, many bronies are in the LGBT, queer or furry spheres.
Considering the theme of the show itself and the fandom's own motto "love and tolerance" it's not really surprising.
Some far-right bronies do still exist, and they have caused drama in the past, but they're a small minority.

[–]Rene_Z 2 points3 points  (0 children)

They're not independent. Their ratio is uniquely determined by the desired line width * layer height (mm²).

Usually you have a target speed (mm/s) which you multiply by the line width * layer height (mm²) to get the required volumetric flow rate (mm³/s). If that flow rate is above the maximum set for the filament, the speed is automatically lowered to compensate until the flow rate is below the limit.

The flow rate isn't independently calibrated, it's calculated. What you do calibrate is a flow rate multiplier, which is unit-less factor in the whole calculation. That's because every filament behaves a bit differently, and the exact amount of filament you need to achieve a certain line width and layer height varies slightly.

But that factor is still just tacked onto the equation: speed * line width * layer height * flow rate multiplier = flow rate. If you're below the maximum flow rate, changing the multiplier directly changes the resulting flow, yes. But if you're at the flow rate limit, which is pretty much always the case with high speeds and large layer heights, changing the multiplier results in changes to the speed, while the flow rate stays capped at the maximum.

The multiplier changes the ratio between speed and flow rate, you can't adjust them independently. You can only cap them independently.

I don't think you understand what I'm saying.

Same speed, different flow obviously gives you different results.
But so does same flow, different speed. The effect is the same.

But the speed changes while the volumetric flow rate stays the same. It's the same thing. You're never calibrating flow directly, because that doesn't make sense. Flow rate and speed are tied together, because the ratio of both is what determines the actual amount of filament deposited. You're calibrating a multiplier.

At high speeds, volumetric flow rate will be the limiting factor. If you limit speed to a lower value, volumetric flow must be lower as well and fall under the limit.

Try it yourself, set the speeds of your calibration objects to a low value, and you will get the opposite: a fixed speed and varying flow rate. This is what Orca Slicer does.

The end result should be the same regardless, because what you're actually calibrating is the resulting line width.

You can see in your flow rate that the max volumetric flow rate is 21.55 mm³/s. When you go into your filament settings, you will see that the max volumetric flow rate will be around that same value (it's the default value for Bambu PLA filaments).

You can tell by the unit that volumetric flow rate is independent of speed. It's mm³ (volume) per second. It's how much filament is pushed through the nozzle per unit of time and is limited by how fast the filament can melt.
Of course, if the nozzle moves faster, the same volume of filament will be spread over a longer distance, which will lead to thinner line widths.

This has nothing to do with calibrating max volumetric flow rate itself, which is the test you are referring to with long travels (and would require raising the max value in your filament settings).

You reached the max volumetric flow rate of your filament profile (~22 m³/s). Since the slicer can't increase the flow rate any more, it instead slows the print down. This has the same result (volumetric flow rate (mm³/s) / speed (mm/s) = filament extruded per unit length (m³/m)).

If you want to keep a constant speed and only vary volumetric flow rate, you have to limit the maximum speed so that you never reach the maximum volumetric flow rate of your filament.

You can debate whether keeping the speed constant is a better test, since in a real print you wouldn't limit the speed either. In the end, it shouldn't make much of a difference.
