    Hello! You may have heard stories about glass plate having one side which brings you slightly better adhesion compared to the other side, or perhaps you have experienced this first hand yourself. Allow me to provide you with some background information and some instructions to figure out which side you should be printing on and which side you should use if you want to add an adhesion sheet. The difference is first introduced during production. When our glass plates are being made, near the end of the production line there is a hardening process. During the hardening process, the plates float on a layer of tin and are heated from above. This creates a difference between the two sides. There are two main factors that ensure good adhesion to the glass plate: wetting and flatness. Wetting is the ability of a liquid to maintain contact with a solid surface. Lower surface tension means better wetting. The non-tin side (i.e. upside during the hardening process) has a lower surface tension than the tin side. Therefore the non-tin side is recommended to print on. If the sticker that is on your glass plate fell off, you can do a simple small test to identify which side is which by placing a drop of water on both sides of the glass. (Not at the same time though). The non-tin side, the side you want to be printing on, is hydrophilic and the water disperses. On the tin side, the water will form a droplet (this side is hydrophobic). If you want to use an adhesion sheet, it is recommended to stick it to this side. Hope this helps! Let me know below if you have any further questions!

    There are 400+ people working for Ultimaker. There is no way that everyone can know what is happening at any given moment. So yeah, I do work for Ultimaker, but that doesn't mean that I can give answers about everything that's going on at any given moment. I understand that people are frustrated about it, but there is also no need to start lashing out at anyone working for UM that is responding to things in this topic. I'm trying to help in what limited way I can. Not because I have to (because hey, it's not my job), but because I feel that it's important to do so. Let's turn it around a bit; I'm seeing a lot of frustrated people. But due to me not working on the right project, there is little I can do about it. What I can do is respond at some of the other remarks that were being made. Upon doing so I suddenly get attack for doing that. What kind of message do you think that gives off? If that happened to you, would you feel that it matters that you're trying to help? I doubt it. So yeah. I do respond a bit cranky if my genuine attempts to at least do something get annoyed responses. It frustrates me that what little I can do about this issue isn't going to fix it. I also get that your frustration is even worse because there is even less that you guys can do about the problem and for that, I'm really sorry. There just is no more information than "We're working on it as best we can". I know that's not a satisfactory answer because quite often this is used as a "shut up and leave us alone" response to get people to stop complaining. But it's the best answer I can give because it's the truth. We are working on it, it is something that a lot of people (myself included, even though it isn't my problem) feel strongly / responsible about.

    Now available is a Linux AppImage that runs on an armhf system (e.g. a Pi 4). It has received minimal testing but it does appear to work (I sliced a benchy OK!). Obviously, even the amazing Pi 4 is still quite limited compared to most laptops, etc. so don't expect stellar performance but it is surprisingly usable. I think it exceeded my expectation. It is highly recommend that you have 4GB of memory and a CPU fan! Known limitations are that currently the layer view only works in compatibility mode and that the UI QML is slow due to lack of JIT support. If you try it out, please post feedback on this thread or open an issue at https://github.com/smartavionics/Cura/issues. You can find the release at https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0. Remember, all my builds are provided with no warranty whatsoever. That said, I try to fix issues where I can.

    The sidebar plugin will always have to be updated for new versions of Cura. It "patches" specific parts of Cura, and when Cura is changed those patches don't work anymore and have to be redone. I do think there are still good reasons to prefer the sidebar implementation over the floating panels, so I will release an updated version of the plugin at some point, but there are some complicating factors at the moment.

    I don't want to sound like a total fan boy, but...... I have owned and still own a number of printers from many manufacturers, including Prusa and nothing comes close the UM printers for accuracy, print quality and repeatability. The reality is FDM by its very nature of melting plastic and extruding it on top of another layer of plastic will mean there are a level of variables which will always be present, different brands of filament, ambient temperatures etc etc, to get a FDM printer to be totally plug and play is just not possible, however you can get close and (for me) UM get by far the closest. When I owned the Prusa I would spend more time tweaking the printer than printing parts, which at first was fun but then just got annoying. Obviously the price point is different, but for me the UM printers offer as near as plug and play as you can get and once you know what you are doing and update profiles for different models and materials they are (for me anyway) as good as it will likely get for FDM. And as for accuracy and print quality, way way better than the Prusa for example (for me anyway). Still haven't got my glass plate though 😛😛......

    Fantasiewerte sind es nicht - es sind max. Werte, die mit EinschrĂ€nkungen erreicht werden können. Da du so gern auf Autos, insbesondere eines Konzerns rumreitest, du kannst ja auch z.b. bei einem Auto, das max. Drehzahl 7000 U/min hat und dabei 230 PS entwickelt, die Drehzahl fahren und hast die Leistung. Das ist fakt. Ist Physikalisch berechenbar und auf der Rolle Verifizierbar. Aber kĂ€me jemand auf die Idee, mit 7000 U/min. mit seinem Auto dauerhaft durch die "Pampa" zu geigen? Vermutlich nicht - es sei den, der Sprit ist Ihm zu billig und er will seinen Motor "killen". Da genĂŒgt es schon, dass im Winter direkt nach dem Starten des Motors sowas zu probieren oder nach dem er richtig Heiß gefahren ist, einfach ausschalten. Aber die Drehzahl kann er und die Leistung hat er da dann auch. Wenn du soviel Bauraum brauchst, kommt es, wie @DirgDiggler, schon versuchte, dir zu erklĂ€ren, auf dein Bauteil an. Manchmal, je nach Bauteil genĂŒgt ja schon 45 Grad drehen, aber da hier keiner Weiß, wovon du redest, wird da nichts konstuktives bei "rumkommen"... Theoretisch wĂ€re auch die Kamera abmontierbar, was auch noch mal in Y die max. LĂ€nge etwas weiter ermöglichen wĂŒrde, wenn man das beschriebene nachvollzieht. Gruß, Digibike

    I am not really a fan of browser-based GUIs, because that leaves you with an additional variable that you are dependent on but have no control over: the browser. Here are a few examples. Firefox was excellent until one day they changed the whole UI and concept, after which it broke all add-ons and became useless for 80% of its users. This broke a lot of people's workflow. Advanced users - like most people here are - tend to install a lot of add-ons in their browser, which may create additional dependencies and trouble. Some people - or some of these add-ons - may disable java, javascript, flash, silverlight, active-x, cookies, external fonts, third-party images, right-click functions, pop-up functions, resize-functions, and whatever else. If you have a good but not very common browser, like Pale Moon (=a Firefox derivation that has kept the old GUI-concept with menubar and statusbar), then this is often not recognised by the server. And then the server messes-up its webpages by *assuming* stupid things, for example that I have a micro-screen of 320x240 pixels instead of my real 1920x1080 pixels. So it sends me garbage instead of standard HTML: it sends fonts of 5cm high, so only a few lines fit on my huge screen. The bigger the organisation, and the more they are specialised in communication (e.g. news-sites and newspapers), the worse this gets, and the less they communicate. A lot of modern browsers even mess-up perfectly valid and simple standard HTML, which by design should reflow automatically in the available window. The browser should take the default font-settings if not specified, without changing them. But they don't. For example Google Chrome Mobile rescales some paragraph's font-sizes (sometimes making it larger, sometimes smaller), but not other paragraphs. And some browsers refuse to reflow text, so it falls off the screen. So you can't even limit yourself to old-school 1995's HTML and forms, because even these break today. You don't want that kind of trouble in a slicer GUI. Cloud-based computing is even worse: then you become dependent on a very unstable variable: the internet/network, coming with all its interruptions and its hazards (virusses, spyware, interception, industrial espionage...). It is unusable while moving (train, plane) or in remote areas: even Germany has no internet in lots of its eastern rural areas. And the data going over their monthly limit, and you going over your budget. Also, this creates GDPR and similar legal problems. So I prefer independent standalone applications installed on and running on the local computer. One application per function. Preferably with all user-settings stored in the same directory as the main program, or a subdirectory "user-settings". Not splattered all over the harddisk in unaccessible directories. So that it is portable. Although of course all programs should use generic and standard datafiles for smooth data-exchange. I am aware that my view may not be "politically correct", but this has proven to work best (for me).

    What do you mean with "it cannot use with Octoprint"? Because the Octoprint plugin is not working anymore? Cura itself cannot communicate with Octoprint, but there is a plugin to send sliced files to Octoprint. Normally the plugins have to be adopted for new Cura versions, so due to the fact that Cura 4.1 is beta, a working version of the plugin will be released latest when Cura 4.1 is released. But @ahoeben is normally faster than light and you will see a working version soon.

    Hello. Recently, I bought a Duet3d ethernet for my JennyPrinter3D (Ultimaker 2+ extended clone). I decided to change the original board, which was rubbish, for this one. It looks great and the webpanel is incredible. I am trying to configure the new board with reprap configurator but it is a little bit complicated. Could anyone share their parameters? It would be very helpfull. @Neotko I saw your video of Duet Connection in Youtube. It was very useful (me fue muy Ăștil y estĂĄ todo muy bien explicado). Regards!

    My understanding is that there are many grades of aluminum but only MIC6 grade is flat and stays flat. But after you heat it and cool it for months it starts to warp. Worse than the glass. ALSO the aluminum wasn't for PLA or most other materials - only a few of the new materials work better on aluminum. I could be wrong about these things - I'm really not an expert. Ultimaker doesn't like to release something unless it works very very well and consistently. I think they have learned their lesson about announcing things early.

    Gr5 Not to be argumentative and yet; it is “highly” probable and very likely that the percentage of owners/end users and businesses active on this forum is a token percentage; who knows; maybe it’s 0.1% which would equal 100% based on your sampling. Furthermore; I personally speak with a couple USA distributors that without reservation share that they too have the same trouble getting element of urgency support as such attempt as able to satisfy the customer in house. Having shared this; I too feel that the Ultimaker Team is far less connected to the end user, particularly when there is an issue than they want all to believe.

    During my spell working in the Art department on 'Avengers Age of Ultron' I was asked by the production designer to build a prop to help dress the interior set of 'Stark Towers' The model was to show the new section of tower that replaced the damaged section from the original film. As I only had 4 weeks to build it (including 3d modelling) we needed to simplify the design a bit, hence the lower portion being in laser cut acrylic. Using my trusty Ultimakers I think I pulled off the desired effect, even if it only appeared in the movie for less than a second!

    The water absorbtion of nylon is a kind of double-edged sword: Before printing, you don't want the material to absorb moisture. Because of the heating in the printcore, the absorbed water will create bubbles and give a bad surface, little holes and in the wors case clog your nozzle. So it's important for the priniting process to keep the nylon filament dry. After printing, the model will absorb moisture out of the air and of course when it's put into water. But this does not affect the properties of the material in a negative way. It will make your model slightly stiffer more impact resistant.

    You can always check whether the printer will print correctly by looking at the preview tab. In this tab you see what the printer will do. You can however be relatively sure that yellow parts will just print.

    Hello, During the years the site has been getting better and better, so this is a good evolution. But I think it could still contain a bit more diagnostics manuals and tips and tricks that come back very often in the forum. For example: - A detailed list of all existing and well working bonding methods to the glass bed: the "official" glue stick, the official glue stick + wiping it with a wet tissue to egalise it, 10% wood glue in water, hairspray, my salt method (PLA only), 3DLAC, sheets, etc... With all their advantages and disadvantages. So that people can try them, and choose the one that works best. - A detailed list of possible causes of underextrusion, like the one gr5 has (ask him if you can reuse it). - Etc..., just all the things that keep coming back on the forum.

    How can the very latest, cutting-edge design software combine with a 5,000 year old manufacturing technique to deliver outstanding weight reduction opportunities? Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts upon the energy usage of the product during it’s service life. Lighter products mean less fuel to move them around, which can make our fossil fuel reserves go further, or make more efficient use of the renewable energies that we’re now beginning to adopt. Generative Design (GD) is the very latest design software released by Autodesk and is now included in Fusion 360, which is at the heart of their "Future of Making Things" strategy for Design and Manufacturing. It changes the way we design things and can deliver very efficient designs that deliver structural performance with optimised use of material. The aerospace industry is expected to be one of the early adopters of this technology because in that industry the cost and environmental savings from improved fuel efficiency carry the greatest rewards. Also, I see interest from the automotive industry for the same fuel efficiency reasons, but in the long term the drive for lighter weight parts could benefit many industries, even those outside of transportation. Another example of the benefits of lighter weight alongside reduced material usage is that shipping costs for parts reduce as their weight reduces, which can therefore also deliver cost efficiencies. GD is targeted initially at metal parts where the biggest opportunity for light-weighting exists. The complex forms it generates though often means that parts conceived in this way cannot be made with conventional manufacturing routes. They therefore need to use Additive Manufacturing (AM) techniques to produce them. The route of using high energy, laser-based AM to do this comes with associated high costs because of the specialised set-up knowledge required together with expensive processing, and post processing, to deliver a quality-assured part. This project explores the possibility of a more cost-effective route to a metal GD part which, even though at this stage may be just used for a small quantity of evaluation prototypes, can act as an enabler for understanding the potential that GD has to offer. This is the baseline design for this project. It is an aluminium bracket design similar to those used in aerospace applications to mount control surfaces, and in this form has not been optimised for weight. This design would weigh 383 grams in the intended material, aluminium A356. After processing this through Generative Design in Fusion 360 it’s time to review and evaluate the many alternative design options presented and decide upon the design that is considered the most appropriate taking into the other factors that have an influence on design selection such as manufacturability, aesthetics etc. This was the design option chosen for this part and Fusion 360 was used to create the final version of the model. The bio-mimicry that’s evident in most of the designs created by GD is interesting to see, in this case the design of the part can be seen as essentially a swept I-beam (which engineers, especially those in construction, are taught is a strong section), but with tendon-like attachments back to the mounting points to carry the tensile loading that’s created by the applied loading conditions What GD does is to turn the standard design workflow that we’re familiar with on it’s head. Traditionally we design a part and then stress test it virtually to determine if it fulfils the required structural performance. Any failures seen during this process require an iterative loop back to the design to correct them. With GD the stress analysis is a core part of the design synthesis, and happens as the part design iterates, which means that the output at the end should meet the requirements of the intended loading requirements. The software is searching for an optimal solution where the stress is ideally evenly distributed across the part as can be seen above. To prove that everything is good with the finalised design this part has then been virtually tested again in Fusion 360 to confirm that the original loading requirements are still met So we've created our lightweight part design, and maybe now we need to produce that in aluminium A356 to do some physical testing, but don’t want the expense of using a metal AM process. What follows is a way of achieving this where FDM 3D printing can play a role as an “enabler” to help create the final parts in conjunction with a very old (if not ancient) manufacturing technique called investment casting. This technique is 5,000 years old according to Wikipedia. The company involved with casting this project is Sylatech who have been using Ultimaker 3D printers as part of their process for investment casting of prototype parts Sylatech took the .stl file of this model and used it to create a 3D print of the part on an Ultimaker 3 in PLA. This PLA part was then used as the pattern in the investment casting process where it is submerged in plaster under vacuum conditions to ensure that all air is excluded from the mould and creates an accurate reproduction of the surfaces of the part. The picture below shows a display box which demonstrates the set up of the 3D printed parts partially encased in plaster. Once the plaster has hardened the casting box is put into a furnace at very high temperature in order to burn out the PLA, leaving behind a cavity into which molten aluminium can be cast. After solidification of the metal, and cooling of the mould, the plaster is broken away from the parts, and then they can be quickly and easily removed from the material feed gate resulting in these aluminium A356 versions of the PLA original. The final part weighs 122 grams which is a weight saving of 68% over the original baseline part, which shows the potential that GD has to make significant reductions in weight and material usage. Using this method we now we have an excellent quality physical part made very quickly in the final intended material in order to commence some physical testing.This is a different route to get to that physical test part in metal at a fraction of the cost of having it metal additively manufactured. It also shows how a brand new, cutting edge piece of software that only became available in May 2018 can combine with FDM 3D printing (which many people still see as a new technology even though it’s been around for over 20 years) and a 5,000 year old manufacturing technique to deliver potentially huge benefits in weight and material usage. Using the investment casting route in this case study is why I chose the title for this article, and shows that we can effectively go “Back To (Deliver) The Future”. Do you see the need for lighter weight parts in what you do, and can you see the potential benefits of using Generative Design and this method of producing metal parts? I'd welcome comments, suggestions, and discussion about any aspects of the above article, the next steps that I'm looking at are how this process could scale up to batch production of the parts using 3D printing techniques that could support low volume production quantities

    Cura stores a configuration per version, so you can always go back to a previous version if a new version doesn't work for you. When there is no configuration folder for the version you are running (eg when you run Cura for the first time), Cura will see if there is an older configuration that it can copy over and upgrade so you don;t have to reconfigure everything. I think in your case it picked up a configuration from an older version that you did modify (you added a Creality CR10 definition). That old configuration points to a printer definition that does not exist in the new Cura. This causes an error. Removing the upgraded configuration will only result in having the same old configuration with the reference to the missing definition being copied over and upgraded again. By removing the contents of the folder, but leaving the empty folder in place, you trick Cura into believing there is a configuration for this version of Cura in place (there's just nothing configured). So this is the way to start fresh without copying an older configuration.

    Generell ist es immer besser, Löcher kleiner zu drucken und etwas aufzubohren, damit Sie wirklich rund sind. Eine STL ist ja nichts anderes, als eine Beschreibung der Konstruktion mithilfe von Dreiecken. Da fĂ€ngt schon das erste an: Je feiner die STL-Auflösung ist, desto feiner können die Kreise dann letztlich auch "angenĂ€hert" werden. Doch damit steigt auch expotenzial die Datenmenge an (FilegrĂ¶ĂŸe). Dummerweise ist es allerdings so, dass der Drucker ja auch nur eine gewisse max. Auflösung zulĂ€ĂŸt. Mit anderen Worten: Ab einem gewissen Punkt wird man nur eine Zunahme der File-grĂ¶ĂŸe feststellen, aber keine QualitĂ€tsverbesserung beim Druck = verschenke Slicer-zeit und verschenkter Speicherplatz - zumal ab 65536 KB die Slicer Probleme machen können... Das ist der eine Grund. Der andere hat was mit der Berechnung der Materialmenge zu tun. Nimm mal den Kreisdurchmesser, multipliziere Ihn mit Pi, Nun zeichne mal eine Linie mit dieser LĂ€nge. Oberhalb und unterhalb der Linie mit 0,2 mm Abstand eine weitere Linie. Die mittlere Linie stellt die Strecke dar, die beiden Ă€ußeren Linien symbolisieren im Prinzip den Ă€ußeren Bereich der Raupe, die der Slicer dafĂŒr berechnet. Nun nimmst du den selben Kreis, der wieder die berechnete Menge darstellt. Zeichne um diesen Kreis wieder mit 0,2 mm Abstand Innen und außen 2 Linien. Du kannst das sofort sehen: Die innere Kreislinie ist deutlich kĂŒrzer als die berechnete RaupenlĂ€nge, die Ă€ußere deutlich lĂ€nger. Nun, ein (kleiner) Teil wird nach außen fließen, da hierfĂŒr Zuwenig Material vorhanden ist, aber der grĂ¶ĂŸere Teil des Zuviel an der Innenseite wird wohl kaum das restliche Material nach außen verdrĂ€ngen, oder? Wie immer, wird der geringste Wiederstand bevorzugt - und da ist im Innenbereich doch ein Loch... Du siehst, hier spielen 2 Probleme mit rein, um wirklich Maßhaltige, runde, Löcher und Wellen drucken zu können. Ich nehme da als Faustregel immer die DĂŒsenbreite bei Lochdurchmessern weg und bei Wellendurchmessern dazu. Da bekomm ich fĂŒr gewöhnlich sehr saugende Passungen. Ab ca. 16 mm Durchmesser nimmt der Effekt ĂŒbrigens i.dr. ab - liegt daran, dass da die Teilsegmente immer lĂ€nger werden, die den Kreis beschreiben... Gruß, Digibike

    I would stay away from GreenTec/PlaTec for mechanical parts that are subject to force in any way (based on my own experience). It has very good resistance to heat, but that material gives in (softens) after a while. How long depends on the amount of force it is subjected to.

    Bonjour StefMtz, Bienvenue sur le forum, tu as quel firmware sur la machine? Sinon si tu penses que le filament n'est pas extruder assez vite, ce que tu peux faire c'est le pousser Ă  la main, tu lĂšve le levier du feeder et tu pousses le filament Ă  la main par exemple au moment du prime du core. Je pense que les tempĂ©ratures des cores doivent ĂȘtre bonne, ça m'Ă©tonnerait qu'il y ai un soucis de ce cotĂ© la. Peut ĂȘtre qu'il y a une rĂ©tractation un peu longue si tu utilise la procĂ©dure de chargement du filament (perso je le met toujours Ă  la main ça va plus vite).

Ich vermute der Vorteil dabei ist, das der Slicer schon im Vorfeld (grob) den DĂŒsenversatz berĂŒcksichtigen kann und damit "weiß", ob der Druck wirklich in den Bauraum passt. Wenn man z.B. eine ganze Druckerfarm mit Cura Connect betreibt, ist letzteres ziemlich wichtig, weil dann automatisch der passende Drucker fĂŒr jeden Druckauftrag gewĂ€hlt wird.

    That's unfortunate. At the moment remote printing is only supported by Cura indeed, so either on a 2nd desktop or a laptop that you take somewhere else. I can't go into details here but we'll be adding a lot more features in the (near) future, this is just the basis for having a cloud connection at all.

    Den kompletten Cura Ordner (mit darin liegenden unter Ordner) kopieren, und am bestens falls der bei deinen neuen PC schon erstellt wurde erstmal komplett löschen (bei geschlossenen Cura natĂŒrlich), dann den Ordner von deinen alten PC rein kopieren Und keinesfalls die Dateien von 3.5 in Ordner 3.6 kopieren/verschieben, das macht Cura automatisch beim ersten start und nimmt dann Änderungen vor die durch der Versions Upgrade nötig sind.

    VERY helpful. The re-design of my part has completely resolved my problem and the new parts print perfectly. But I'm sure I will run into this problem again, so the above information will be very helpful in resolving those future headaches! Thanks! Regards, Ray L.

    Well for those interested theres not much difference in detail in dousing the object in acetone other than you get more spots for longer than a quick brush. But thats about it, i guess i must not have covered the bottom of this other one above all that well. The issue with over brushing is that after you have brushed off the additives in the PLA PHA then there is less smoothing material left behind because you have essentially washed it off/out. If you over acetone it could split due to drying out. But I must say since using the s5 I have not had one model split on me regardless of how much acetone I used. It must be the fact that on my UM2 I was printing so low that some layers had simply not bonded as well as I had thought.....Oh well some nicer photos, had to be done. The one on the left has been brushed on for a whole minute as i didn't have enough acetone to dunk it! and the one on the right is just a quick wax on and job done. I finally need to buy some more...Id say 1 litres of acetone lasts me about a year. Thats good value!

    I was able to make it to work! This is how the G-Code looks now: M140 S{material_bed_temperature} ;set bed temperature G28 ;home all axis M190 S{material_bed_temperature} ;wait for bed temperature M104 T0 S{material_print_temperature} ;set hotend temperature G29 ;auto bed leveling M109 T0 S{material_print_temperature} ;wait for hotend temperature Now my prints are more "productive" - instead of waiting for the nozzle and/or the bed to heat up, then home XYZ, then start to auto bed leveling; now it first heats up the bed (if it set to do it), in the same time it homes XYZ, and wait for the bed's target temperature. When the bed reaches to its temperatures, the printer will proceed to heat the nozzle and while the nozzle heats up, auto bed leveling is being executed. When the heating is all done, print starts.
