  2. Yeah. We will keep this available. I'd like to think that this is why engineers like our product. If you want to, you can "open the hood" so to speak, in order to mess with the internals. This is why we only give errors for settings that we *know* are impossible or will break the hardware. Really improbable values will just net you a warning.

    Ultimaker a un grande nouvelle : la S5

    Bonne question : une extension future ?
  4. I hope it is always available though....Back in the Analog days, when I worked at a TV station, we would do all sorts of strange things to our production pipeline for special effects like static, jumping video and such just by wiggling wires while putting clean A-Roll and B-Roll tape out to the final recording station. Much like this below Sometimes it tasted good, sometimes, not so much.
  5. > For now, what we can achieve is to reduce the number of settings that exposed to the UI as many as possible That is what Recommended mode does. Even Custom mode, by default, only exposes a very small subset of the available settings. The idea is that the interface can grow with the experience of the user. Unfortunately, some people seem to be intent to advice even novices to just make every setting visible, which leads to a very suboptimal learning curve. I am not saying the settings UI is perfect (far from it), but thought was given to this.
  6. Ah, I think we're at the meat of the discussion here. We try (and because we can't do it yet, often fail) to provide with settings that should make the model work. But as our algorithms are far from perfect, it could well be that it might be wrong. This is why we at least give people the option to tweak it. In the long run, this shouldn't be required. We try to do as little with the engine for exactly these reasons, but it just doesn't always pan out that way. The setting changes that we had to do between 15.04 and 2.3 are probably the most impactfully change (together with the multi-threading) and they were / are must have features. As for the cooking analogy; I'd like to see it like as "We give you some pointers, but if you want to put chocolate paste on pickles, be my guest."

    unschöne Filamentspuren

    Man könnte vermutlich tricksen: den ersten Layer einem ersten Extruder zuordnen, die weiteren einem zweiten, und dann (ich weiß nicht, ob das geht), beide Extruder in Wirklichkeit von einem Extruder drucken lassen. Aber schöner wäre wohl ein Plugin, der Combing off/on zwischen den Layern wechseln könnte.

    Da gabs wohl schon einen Change Request, der vom Curaprojektteam zurückgestuft wurde: https://github.com/Ultimaker/Cura/issues/2476#issuecomment-357624835 Aussage von ghostkeeper Ich suche aber weiter.
  9. Hello, I am an UM3E owner for about a week now and I've just encountered a problem which I didn't have with my previous 3D printers.... What do I need to adjust to fix the nose?

    3d printer support

    I successfully imported stl and obj files in Blender, and even been able to modify them and then export them as stl for some prints I had to do. However, be warned that the import of the stl will not show the way the object, or support in your case, have been modeled by CURA, but the way Blender interprets and render the object, whihc is quite different. I did a quick test by creating an object in Blender, exporting it as stl then importing the stl in Blender, and the resulting topology had nothing to do with the clean one from the original object.
  11. You would think this would be appreciated by the community at large, but it seems that users of other machines kinda forget that most of those other machines either do not OEM their own version (Few do) or provide really solid machine settings for their brands. There seems to be some strange onus placed on UM to do it all for everybody..... As for the optimal model stuff, well, I will relate a story of a piece of software written with that philosophy in mind and just how yucky it was. It was called "Busy Ray". They called it that because they felt that people were busy and the software should be as Occamish as possible. Start it and walk away. Their sales pitch was "There is only ONE correct solution to lighting and rendering!!" Which was ridiculous on its own as, if that was truly the case, Photographers would not exist as a profession. I mean, how much more simple can it be when Nature itself is providing the lighting for you? The renders we3re horrible, devoid of the personal touches that made a good render of a scene. It was devoid of character and many times, just wrong because it could not keep up with all the parts of a variety of scenes. And, when I say wrong, I mean things like light direction being off and areas of 'bounced light (Ambient lighting)' was as bright and more prevalent than direct lighting......which is just not possible. It was so bad that you cannot even find it on a search anymore....well, I cannot find it and I used to use it as a golden example of not expecting software to solve problems. Consistency is needed along with focus on robustness, and not always new features. But, they also do start off with a bit of the Occam approach by the way it starts out with only the most prevalent settings exposed. It is up to the user to expose any other settings than that. And, then you get wonks like me that just unhide all the settings before knowing what you are doing. Why? To try and figure relationships and just experiment. If I am going to cook in the 3D printing kitchen, I want to cook with ALL the ingredients and tools, not just a few boxed mixes that someone else decided was 'best.' This allows ME to adjust the settings for MY goals and not be limited. What works for an engineer does not really work for my strange organic fractal thingies I put out. And the surfaces I can get away with certainly would not work for them.

  13. I totally agree that your support for Cura should base on promoting the sales of Ultimaker brand 3D printer. The point is well taken. I'm not against it at all. Because everyone has to pay their bills. Smart software developer deserve a better pay. In fact, by supporting Cura can it also promote the sales of your 3D printer in the long run. It is a very smart business strategy compared to some Chinese 3D printer company, who just build a cheaper and better 3D printer. They have no clues how to keep their advantage in the long run. The 3D printer I owned didn't upgrade their firmware according to slicer thus it may not see the tweak or benefit in the latest slicing engine. However, there is one and only one model (not talking about STL model, I refer to slicing algorithm) in theory. If it is not, your model is wrong and go find another one. Majority of new settings might be a must-have. But some like the one impact tool path generation needs to be carefully reviewed. Those settings related to tool path severely impacts print time and print quality regardless of your printing material or the brand of 3D printer. Like the z-seam setting in Cura engine 3.31, I disliked this. After reading how it works, I think it should be deduced intelligently instead of exposing it. That's a nitty-grity. Regarding to the intelligent profile, formalizing human intent into machine understandable format is always a hard subject in computer science. It is like automating software requirement in software engineering. Unless we have a true AI (not talking about pattern recognition like artificial vision, voice recognition and etc), we will never have that day coming soon. For now, what we can achieve is to reduce the number of settings that exposed to the UI as many as possible. Transform those technical settings into novice understandable terminology. That alone can make a night and day difference in term of usability. It will for sure promote the sales of Ultimaker 3D printer as well. My suggestion is that put more focus on UI and make very very conservative change in Cura engine. I have my suggestion in Github regarding to the branching management (https://github.com/Ultimaker/CuraEngine/pull/722#issuecomment-392003445)

    I copy and pasted the email address, and was without the "i" 🙂 I'll try the hello@youmagine.com.

    YouMagine covered in spam

    Is this the email you used as well? It has a typo in it (youimagine). But in a previous message where I informed about YouMagine having the responsibility to remove spam I also suggest to email to hello@youmagine.com instead of support. Did you try this too?

    Like you said, I tried to contact Youimagine to report spam, but the " support@youimagine.com" gives a non delivery message 🙂 end now there is sublininal spam, a copy of an other object posting, with an illegal movie site link added 😕

    You're welcome @Deve. You can change the size and shape of the box, as if modifying your model, instead of stacking the boxes on top of one another. That way you just need one box and not a dozen or so.
  19. It may just be material-dependent, if the molten material is very sticky like hot-melt glue. I have this on my UM2 too with PET, but far less with PLA. Printing much slower and cooler helped a bit, but did not eliminate the effect in my tests. Especially the slow printing helped, since that gives less pressure in the nozzle, and thus less overextrusion on short lines when the printhead hast to slow down. PLA melts into a sort of yoghurt-like consistency which is easily deposited on the print, but that particular PET melts into a sticky elastic glue, which retracts into a ball and keeps building-up on the nozzle. I would suggest: try printing a little test block (e.g. 15mm x 15mm x 15mm), 100% filled, and on the fly adjust printing speed and temp, and keep watching. For my PET, printing at 25mm/s, 0.1mm layer heigt, and 220°C seems to work best (=at the lower end of the recommended range of 215...250°C).

    That is the idea. Right now the UI is far from perfect, but it's better than it used to be.
  21. Simply speaking; The Cura Engine must do these things. The idea that there is a simple model that fits everything is false. The solution space is vast. Not only are we talking about differences between materials (PLA, ABS, CPE, PVA), inter material variation (Blue PLA vs metalic PLA), Machine variation (Which is it's own fied; Accelerations are different, has bowden tube, different behaviors, you name it), model variation, etc. The notion of oxxams razor is a nice one, but fairly naive. Compare this problem with making an autonomous car. If you're only writing software for a single instance thereof, you don't need a lot of exposed settings. All cars you make it for will have the same type of sensors, the same engine and the same interface. We made it really difficult for ourselves by not doing that. We made a bit of software that should work for *all* instances. So we need to have those settings (eg; Sensors are different, speeds are different, even interfaces are different). We could make it simpler. It would be doable for us, but the price would be destroying the possibility to use it for other machines. So there isn't just "one" model. There is perhaps one model that can "Get most models working for PLA on an Ultimaker". Those parameters won't work at all for a machine that has a direct drive or when printing with ABS. Also note; Only the frontend was redesigned. The engine is one continued process to get to this state. As for optimisations; Yes, we mostly focus on stuff that helps ultimaker. Makes sense as they pay me. We're already doing a lot of work that helps others, so we kind of have to draw the line somewhere. As for overfitting on models; We don't. We fully understand what overfitting is and why it's bad. I also disagree with the idea that there are so much hacks in the engine. Is that code the best maintained code out there? No. There are architectural mistakes we made there. But i don't believe that there is a simpler model that will have the same results. The creation of models with different speeds is intentional. I've also seen vast improvements of g-code since the legacy version especially when using dual extrusion (and of course; When using ultimakers, because we provide the right settings). Now, I do believe that profiles can be smarter. Changing a setting is an action; It makes property X of a print better and property Y worse. But with 500 ish settings, that is a lot of knowhow to have in the head of a user (and thus is unreasonable). But users perform actions because they have an intent. If we can somehow capture intent and transform them into actions we can get what we want.

    Nice, how did you apply the paint? I think the top actually looks pretty good as the way the pink is applied makes the shirt look a bit transparent. Did the print have any support material too?

    BB 0.4 Nozzle clogged printing PVA

    I can only confirm the advantage of a PVA brim instead of the PLA brim. This should be a default in Cura. @Tomhe / @KristelB what do you think? I usually don't change the horizontal expansion on the support in order to make it sturdier but the support join distance. I also find the prime towers for two different materials still a bit thin. I increase the thickness to 3-4mm.

    UM3ext can't start a print....

    Hello, the active leveling was off because i couldn't manage to start a print with it, error each time ! even if I leveled the build plate manually 😞 After searching on the forum for similar issues, most of the people trying to repair this mess breaks the printcores, if not the entire thing ! I'm contacting my local resselerfor support this afternoon 🙂 Thanks !

    underextrusion multiple models ?

    Hello, I never actually changed my TFM coupler, but after checking, there are no apparent damages on it, no burns or anything... Should I change it anyways ?

    Noob question about internal fillings...

    If you like the simple push-pull user-interface and workflow of SketchUp, I would suggest you take a look at DesignSpark Mechanical. That has a similar push-pull style of user-interface, is easy to learn, and it is also free (only requires registration). In 3 years time it never gave me any STL-problems. In Youtube, have a look at the various demo-films to see if it appeals to you. There are also good tutorial vids.
