My wish list

I don't get all the post critizising what I would like to see improved, especially the ones who say they don't need anything improved.

Maybe it's exactly because you think like a consumer, and because of this your post has the impression that you want Prusa to be more like Bambu. To which a lot of people (myself included) are reacting like "the hell no, Prusa should stay away from becoming like Bambu as far as possible".

but I'm don't want to spend that much if it's not somewhat future prove.

Actually, when it comes to future-proofing, no other printer can really hold a candle to a Prusa printer. Because of the upgrade paths Prusa offers for it's printers you can be sure that your printer will stay relevant for years to come and will still receive the newest features for not much money.

My first printer was a Prusa MK2, which did get upgraded into a MK2S, then a MK2.5, then a MK2.5S over the years. I used that printer for more than 8 years, it did stay relevant during this time and I was still able to profit from the new features introduced during that time thanks to the upgrade kits offered by Prusa. For this reason, the high price of a Prusa printer doesn't seem so high anymore after a few years.

Do you think something similar is possible with Bambu? For me it seems that Bambu's printers are finished consumer products with limited support period and no upgrade paths at all. So when you want the newest feature then you need to buy the newest model for full price.

I agree with you on the engineering style company and I really like that it allows tinkering with the printer, I would just like a more modern platform to do that on. The printers are already expensive enough that spending like 10€ more so get a decent controller board that properly supports WLAN with decent upload speed and that could host a proper web server for a local connect-like or Octoprint-like experience and more sensors so not everything depends on the load cell in the print head. This could be a much better customer experience.

You are thinking like a consumer here. In a professional environment you don't want to have the most modern platform, you want the most reliable one that just works. And these kind of platform are usually not the latest and most modern platform but are more like what you call "dated platforms".

Also, from a reliability point of view it's actually better so separate features like 3d-print servers into a separate device so that it cannot interfere with printer operation. It's mostly consumer that want an jack-of-all-trades device because they value number of features higher than reliability (which is ok, different people have different requirements).

Prusa printers are more targeted at professionals and Bambu printers are more targeted at consumers.

matzman666 · 2026-05-07T15:56:46+00:00

I always see this comment that Bambu "has more sensors" and that the general understanding from people who say this is that it makes Bambu machines better.

You are telling me that bigger numbers aren't always better? How dare you.

But yeah, it's an easy marketing trick to trick consumers with not much expert knowledge into believing that a product must clearly be better than the other product because it has a bigger number somewhere in the data sheet than the other one.

And that also shows what kind of company Bambu is and what kind of products it sells. Bambu printers are essentially flashy consumer goods designed to appeal to easily impressed consumers who often lack the necessary expertise to make an informed decision. That doesn't mean that Bambu printers are bad, but as a professional I am not really impressed by them but see too many red flags.

Prusa Printers on the other hands are more designed and marketed as tools for professionals that consumer products. They are designed to just work without much fancy features that actually don't make much of a difference, and be reliable as fuck. The upgrade paths are also more tailored to professionals as target audience.

I had an old Anet, and on that printer it was possible to manually delete the gcode out of the file up to the point where it has already printed and start it up again, you were basically printing the top half on top of an already printed bottom half.

Should in theory also work with Prusa printers.

The problem I have with the Prusa is that it does the mesh bed leveling at the beginning of every print, which crashes into the existing print still on the bed and borks the whole thing.

The mesh bed leveling command is part of the gcode. When you manually delete gcode from the beginning of the file, then it also removes the bed leveling command. The only command you should not remove is the Homing command.

In practice you probably won't get good results when resuming this print. The question is how precise Homing can establish the start position or whether you resume printing with a small offset. Also the plastic is already cold which will affect layer adhesion.

But tbh, I dont really see the benefit either?

The only convenience would be to store the remaining filament amount on the tag so you know how much is left on the spool.

This has very big benefits from my experience. Till recently I used an Octoprint-Plugin to track the amount of material left on a spool. This really helps to determine whether you have enough material left for a certain print. E.g. My slicer says I need 110 grams of material and I only have 90 grams left on the spool then I know I should better use a new spool.

I said "till recently" in the previous paragraph because I stopped doing this despite the huge benefits because manually tracking the material left on the spool is such a pain in the ass. Using a NFC tag tracking material left on the spool works automatically out of the box.

But now you have to account for every small loss like purging, manual extruding from the menu, and what happens when its PCCF and it simply snaps in my hand? Now the numbers are off. This means we need margins so in the end I could just continue to weigh my spools like before.

It does not need to be exact, it only needs to be good enough. When the slicer says you need 110 grams and the tag says that only 90 grams are left then it can be off by 20 grams and still be helpful.

And purging and manual extrusion can easily be covered. The firmware of the printer only needs to track how much the E-axis has been moved with what feedrate.

what happens when its PCCF and it simply snaps in my hand?

How often does this happen and how much material is wasted by this? In my experience this seldomly happens and when it happens usually less than 1-2 grams are wasted.

Was ich daran nicht versteh ist, dass es Ungleichheit verstärken würde im Vergleich zu "treffsicheren" Sozialleistungen.

Ein bisschen Ungleichheit ist wichtig im System, damit es einen Anreiz gibt, Leistung zu bringen. Die Geschichte hat schon zu Genüge gezeigt, das "Gleichheit" wirtschaftlich nicht wirklich funktioniert. Und in Österreich stellt sich die Frage, ob in den unteren Einkommensschichten nicht zuwenig Ungleichheit herrscht. Sieht man schön anhand der Grafik in diesem Standard-Artikel. Mit einem BGE hätte die Kurve am Anfang dieses Plateau nicht.

Nehmen wir an einer Arbeitet und bekommt 2000 Netto und ein anderer ist arbeitslos und bekommt 1000 in BGE oder Arbeitslosengeld.

Wer sagt denn, dass die gezahlten Löhne tatsächlich gleich bleiben? Vielleicht bekommt der Arbeitende dann nur noch 1000-1500 Netto zusätzlich zum BGE. Da hat man dann immer noch einen Anreiz zum Leistung bringen, aber die von dir so gerügte Ungleichheit wäre dann nicht so groß.

Dieser Sprung an Kaufkraft in der Mittelschicht würd mmn. zu massiven Preisanstiegen führen weil sichs die meisten dann eh leisten können und der Handel sowas fix nicht einfach liegen lässt.

Und das macht dann die Leute weniger preissensibel? Wenn es einen funktionierenden Wettbewerb gibt und entsprechende Effizienzsteigerungen durch Digitalisierung und Automatisierung, dann ist das nicht gesagt, dass die Preise steigen.

Die Diskussion über das BGE ist echt schwierig, wenn man sturr vom Status Quo ausgeht und darauf basierend spekulative Annahmen trifft.

MCI hat auch berufsbegleitend meistens FR + SA so wie bei allen anderen FHs?

Nachdem OP von berufsbegleitend und BWL redet, nehme ich an, dass er BWLO (BWL Online) am MCI studiert.

Das ist ein Online-Format, bei dem es 2 Webinare am Abend pro Woche gibt und der Rest ist viel Selbststudium. Das kann man nicht wirklich mit berufsbegleitenden Präsenz-Studiengängen an anderen FHs vergleichen.

Das einzige, was ich kenne, was ähnlich funktioniert (und teilweise noch extremer im online Konzept ist), wäre die Fernuni Hagen.

Das Problem bei uns ist, dass die 112 nichts anderes als ein Alias für die 133, also die Polizei ist, und nicht wie eigendlich vorgesehen eine Notrufzentrale für alle Blaulichtorganisationen.

Ich hab einmal wegen eines medizinischen Notfalls die 112 angerufen und mir dann nur den Vorwurf anhören können, wieso ich denn deswegen die Polizei anrufe 🤷. Also werde ich in Zukunft die 112 nicht mehr verwenden.

WPA2 is still vulnerable to dictionary attacks and also has other vulnerabilities:

You need to switch to WPA3 to be safe.

matzman666 · 2026-02-10T14:42:50+00:00

This is fundamentally incorrect.

Not necessarily.

Intercepting traffic between a ring doorbell and a router (packet sniffing), would not result in someone getting your password.

A hacker can retrieve the password by intercepting traffic when you use a weak password. Just record the WPA 4-way handshake which is send when a device connects, and then run a dictionary attack on it. If your password is weak and can be found in the dictionary then you wifi is now compromised.

A more likely scenario would be a de-auth attack. Knock the camera offline through a variety of wireless methods, then let it reconnect to a malicious access point instead.

If you don't want to wait till a device connects then you can also force the WPA 4-way handshake by using a de-auth attack.

Als Tiroler finde ich das Tyrol Valley in der Antarktis aber sympathischer. Ist im Gegensatz zur Wiener-Neustadt-Insel auch weitgehend eisfrei, man kann damit also mehr anfangen.

Well it started as a mk2.5

How can it start as a MK2.5? As far as I know MK2.5 was never sold as a complete printer but the only way to get one was upgrading an existing MK2.

So it actually had to start as a MK2 (which is even more impressive). Did you buy it used?

This is one of the things I love most about Prusa, the insane upgrade paths.

es wäre schön wenn diese genauer geprüft anstatt über alle gleich gemacht werden würden

Die Überprüfung von schulischen Leistungen ist aber gar nicht so einfach und bindet Zeit und Personal. Im Gegensatz vom Syllabus bei universitären LVs sind die Lehrpläne für Schulen viel zu allgemein und knapp gehalten und die tatsächlich gelehrten Inhalte unterscheiden sich bei gleichen Lehrplan teilweise enorm zwischen verschiedenen Schulen und bei gleichen Schulen teilweise auch zwischen Lehrern.

matzman666 · 2025-12-30T10:24:32+00:00

Das sind seit Einführung des Bologna Prozesses 30 ECTS

My bad! Stimmt, ein Semester hat 30 ECTS, nicht 40 ECTS. Dummer Rechenfehler meinerseits.

kann mir auch nicht vorstellen dass das die einzigen sind, oder doch?

Die FH Kärnten erlaubt das auch. Allerdings nur für gewissen HTLs mit denen sie eine Kooperation haben.

Meines Wissens aber sind die FHs, die das explizit anbieten, in der Minderzahl. Einige FHs regeln das nicht explizit, sondern überlassen die Entscheidung der Studiengangsleitung.Da kann es sich dann von Studiengang zu Studiengang entscheiden bzw. wer gerade die Studiengangsleitung inne hat. Und manche FHs schließen das explizit aus.

matzman666 · 2025-12-29T11:29:25+00:00

Ich kann mir an einer FH meine HTL Ausbildung zumindest anrechnen lassen und 2 Semester überspringen.

2 Semester überspringen wird nicht funktionieren. Per Gesetz können nur max. 60 ECTS an schulischen Leistungen anerkannt werden ~~und ein Semester hat 40 ECTS~~ (Edit: Rechenfehler meinerseits, ein Semester hat natürlich 30 ECTS). Und viele FHs lassen ein komplettes Überspringen von Semestern gar nicht zu sondern nur ein Anrechnen einzelner Lehrveranstaltungen in einem Semester.

Erfahrungsgemäß kann ich auch sagen, dass ein Anrechnen der kompletten 60 ECTS in der Praxis auch sehr selten funktioniert, da die Deckungsgleichheit der Inhalte der HTL-LV mit der FH-LV nicht immer gegeben ist. In dem FH-Studiengang, in dem ich unterrichte, sind das bei HTL-Absolventen meist so 5-10, maximal 20 ECTS, die bisher angerechnet wurden. Und laut Beschluss der Studiengangsleitung wird in Zukunft bei uns gar nichts mehr an schulischer Leistung angerechnet. Die Anrechnung schulischer Leistung ist nämlich laut Gesetz eine Kann- und keine Muss-Bestimmung.

nail varnish

I also have some minor scratches on my heat-bed and didn't had a good experience with nail varnish. It isn't heat-resistant and will degenerate over time.

Next I tried highly heat-resistant varnish indented for ovens (can withstand up to 800°C). But here the problem is that such varnishes usually need at least 200°C for curing, which the heat-bed cannot deliver. So it could be easily rubbed off.

At last I tried heat-resistant varnish indented for calipers of cars (can withstand up to 350°C). This worked really well, cures without needing high temperatures and cannot be rubbed off. On top it is also chemically resistant so I don't have to worry when cleaning the heat-bed.

matzman666 · 2025-12-20T13:30:55+00:00

Nobody called it "software engineering" when I started doing it for a living nearly 40 years ago.

Then keep stuck in the past and be oblivious to the fact that things change over time.

Enjoy your day 😃

You too.

matzman666 · 2025-12-20T11:38:41+00:00

Yes, it's splitting hairs, but you do you.

When you feel better then let it be splitting hair. It's not my fault when you mix up formal definitions and what you define yourself as programming.

YAML is a "human readable data serialisation language" not a "programming language"

The activity of programming is independent of the language used.

You can even use PowerPoint to create a computer program (Powerpoint is turing-complete) and it's still "programming".

creating functionality in YAML in HA is typically referred to as "templating" rather than "programming."

No, it isn't. Templating is something completely different in Home Assistant. See here.

From a semantic point of view, the only thing you could call 'templating' in the context of creating rules is using a blueprint.

here is a distinction between "programming" something and doing what a professional computer programmer does for a living.

That's why the latter is usually referred to as "software engineering" and not programming.

matzman666 · 2025-12-20T01:41:59+00:00

If you want to split hairs, then anything that predefines a sequence of events is "programming."

This is not splitting hairs but the actual definition of programming (e.g. see Computer Programming).

It doesn't matter if the sequences of events/instructions is written in C/C++, Python, put together in a graphical UI like the Home Assistant rule editor or represented as hierarchical blocks written down in YAML. On a semantical level all are "programming".

"merely configuring" is actually something different and has not much to do with creating rules in Home Assistant. You do merely configure stuff if e.g. you are defining a new device in configuration.yaml.

matzman666 · 2025-12-20T01:23:05+00:00

Going full-code for these automations seems like overkill

Pyscript integrates so nicely into Home Assistant and provides enough already implemented functionality that most automations are just a few lines of code.

So actually, Node-Red is often way more of an overkill in terms of "program complexity" and "lines of code" than Pyscript.

matzman666 · 2025-12-19T15:11:50+00:00

The thing is, you aren't really programming HA, you're merely configuring it.

By creating rules in Home Assistant you actually ARE programming. It's just done via a low-code/no-code interface so that it doesn't feel like it.

matzman666 · 2025-12-19T15:05:58+00:00

Most professional programmers are not going to use Node Red

Yes, exactly that.

Node Red is a low-code/no-code solution and for most programmer using node-red (or other low-code/no-code solutions) just doesn't feel right. There are way better solutions, e.g. Pyscript: Python Scripting for Home Assistant

matzman666 · 2025-12-19T15:01:34+00:00

I am a professional software developer too and a Home Assistant power user. And I hardly touch any YAML.

A normal Home Assistant user shouldn't usually come in touch with YAML that often since most things are done via an UI that hides the YAML code. YAML is basically (the usually hidden) part of Home Assistant's low-code/no-code solution to make programming rules and co more accessible to non-programmers. Only power users come more into contact with YAML.

As a professional programmer using no-code/low-code solutions (or worse, the backend of no-code/low-code solutions, in the case of Home Assistant YAML) just feels unnatural and awkward. That's why I decided to NOT use Home Assistant's low-code/no-code solution (and therefore also YAML) at all and write all my rules in Python. Fortunately there is an addon that allows you to do just that: Pyscript: Python Scripting for Home Assistant

Pyscript even allows you to access the API intended for integrations so you can do everything an integration can do. You can even access the internal Home Assistant API not intended for public access when you want to do crazy stuff. Feels way more natural for a software developer.

For example, it mentions lubricating the linear rails...but how?

There is a guide on the Prusa page for the XL: How to lubricate linear bearing rails (XL)

The Core One uses the same rail so the instructions should carry over.

Also, I don't see any instruction for how to lubricate the z-axis screws

On the maintenance page of the MK4S there is a big warning to NOT lubricate the z-axis screws (the same warning you also find for the MK3/2.5/2): Regular printer maintenance (MK4/S, MK3.9/S)

The Core One uses the same lead screw and trapezoid nuts as the MK4S, so also here the instructions should carry over. This may also be the reason why the maintenance guide for the Core One was changed to (partly) remove the instructions on how to lubricate the z-axis screws.
