    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.

    true. I bet he made a lot of people very happy without even knowing! in the meantime i've been repeating my nonsense from yesterday. I was fiddling around with my 'quick' sculpt. and only now i realise im going in circles, and now ive ended up on an old version, because all my new ones looked weird, its annoying. i've filmed me making this from a sphere as usual. but ive lost the history now so cant go back. im just gonna print this rough version and see how it looks.... ....I just remembered the very first thing i printed that i made was a sphere as i couldn't sculpt back then, and it didn't look good, but i felt it was possible....somehow, thats what got me so interested 4 years ago...

    Hi Folks, I hope you enjoy evaluating the new gyroid infill pattern, it's very fashionable, right now. Just a quick word to alert you that because the infill pattern is, essentially, a mutating sine wave, it is possible to induce resonance in your printer when printing large areas of gyroid infill if the frequency of the head movement matches the resonant frequency of your printer. So, please observe the print head when you print a large area of gyroid infill the first time and if it is moving side to side more than you would expect, slow the print down to stop the print head thrashing around. When I observed it happening, a 10% speed reduction was all that was necessary to stop the resonance. Reducing the density of the infill will also reduce the frequency.

    The only reason for us to use boron carbide is that we want to absorb neutrons and boron (the 10 isotope) has very good properties for this. Boron Carbide is a chemically stable reasonably priced ceramic powder with high boron content (four boron atoms and one carbon atom). While a softer material with high boron content would have been preferable, there are no such options in a reasonable price range. Other uses is for example as a grinding powder, which explains why it eats 3D printer nozzles ? That is the basic reason behind the Olsson block and the Olsson Ruby nozzle, summed up in a few sentences ? If you are interested in further reading, we have published much of our work in an open access article: http://iopscience.iop.org/article/10.1088/1402-4896/aa694e (Check out the Supplementary Data too for information about the Olsson block and other stuff) There is currently no commercial production of boron carbide filament but there might be in the future. Be ware though, if you even come across it, that boron carbide is one of few materials which is harder than ruby, so it will slowly wear the ruby.

    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

    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.

    What @Steverc1572 and @PatK say together just about describes an issue. I'm guessing it's the same issue. PSA: please be a bit more descriptive when reporting something. What did you do (step-by-step), what did you think would happen, and what happened instead. Especially that step-by-step description is often important to be able to reproduce a bug. A bug that cannot be reproduced often can not be fixed. Finally, it is very helpful if you mention what printer type you added in Cura.

    I kind of understand why he is thinking scaling with pin points will be logical, since he's from CAD/CAM tool background. And many CAD/CAM tool can just send jobs to hardware right away without problems. Starting with curves, sketches and restraints, and export them into paths. It's all logical in that sense, when it's Parametric modeling. What he might not understand is 3D printers and slicers have to deal with Non-Parametric modeling. Scaling in Parametric modeling world can be easy since they work with constraints and paths, but once a model is converted into STL they became static. What he is asking for is that CURA might hv to allow user to pin-point and select vertices on a model to make scaling accordingly... which can be a nightmare and might require a whole new engine and the whole workflow needed to be reimagined. The mechanics of a 3D printer might be similar to a CNC but no it's not the same thing. I also work with similar projects where i have to export joints and pegs in different sizes and clearances. I use variables in e.g. Fusion360 to make constraints work for models in different sizes and export them separately. Eventually I use scripts to automate that, and I still prefer to keep the resizing/exporting and printing procedures separated, rather than trying to use the same file and print different sizes. It wouldn't be a good way to manage files and bad for the workflow.

    The intellectual property laws differ a bit from country to country, and they are very complex. There is *copyright* which automatically makes the creator of any original piece of art the intellectual owner. Then there are *protected models*, in which a company can protect its brands and models. And then there are *patents*, which can protect new technical equipment and manufacturing methods. Copyright is automatic and free, patents and protected models have to be applied for and paid for. Generally: - If you make an original piece of art (=something new, it doesn't exist yet), you automatically get the copyright to it. No one else can sell it without your permission. - Often but not always, the law allows you to make a copy for personal home use only, of a copyrighted work of someone else. This differs a lot from country to country, and also depends on the type of art. - Small portions of a work can often be copied as citations, and for scientific and educational use. In case of discussions, the judge will have to decide if this was fair use or plagiarism. - Generally, it is forbidden to copy and sell anything (or even give it away or put it on public display), unless you have written permission from the copyright holder. - In addition to copyright, commercial models are usually protected as "deposited models" too. - You can not copyright ideas, laws of nature, etc. So it have to be exact, concrete materialised models, texts, music, paintings,... So, you can not make a verbatim copy of an art statue and sell that. But you could make a totally new statue that is vaguely inspired by the existing one. You can not copy and sell existing movie characters like Donald Duck, even not in different poses that are not in the films or in their shops. Big companies like Disney make sure that all their characters are deposited models. You can not sell a verbatim transcription of a speech given by a professor in class. But you can write down the contents *in your own words* and sell that. However, if the data from the professor were indispensible for your text, thus you couldn't have written it without his input, then again the professor automatically becomes co-author of the text, and you need his permission to sell it. Or you can not copy and sell existing models like a Chevrolet Corvette. You need a written permission and license from General Motors to do so. But you could design a new sports car that has some vague similarities to a Corvette, let's say a coke-bottle shaped body. Some people make a verbatim copy and then modify only a tiny little part, to sell it as their own creation. This is not allowed. On the opposite side, some big companies try to suppress anything that even vaguely resembles any of their characters or models, which is not allowed either. So you can not copy a Dart Vader costume and sell that. But you can design a new space suit that has some vague similarities. If you do, it is always a good idea to make sure the thing is inspired by multiple different sources, and you put a lot of your own creativity into it. And document it and keep the intermediate steps, especially if you want to sell it. I am not a specialist or lawyer, but I read a bit on this subject. It is all quite complex, with lots of exceptions and vague borders. So in case of discussions, which are likely if you have a big commercial success, the judges will have to decide. And the one with the most money or patience usually wins... So I suggest that you google a bit on the subject. For those who speak Dutch, the Belgian government has a good website on intellectual property. At least, they had. It is now in the process of being renewed, so I don't know what will come out of it.

    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 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 Einschränkungen 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 käme 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 genügt 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 erklären, auf dein Bauteil an. Manchmal, je nach Bauteil genügt ja schon 45 Grad drehen, aber da hier keiner Weiß, wovon du redest, wird da nichts konstuktives bei "rumkommen"... Theoretisch wäre auch die Kamera abmontierbar, was auch noch mal in Y die max. Länge etwas weiter ermöglichen würde, 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 útil y está todo muy bien explicado). Regards!

    There is a plugin in the marketplace that puts the sidebar back in the semi old stile it was.

    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.

    Right now, that's how Ultimaker Cura behaves. I have an alternative implementation of the wall gap filling in my Cura releases that doesn't shake your printer to death. My releases (which can be installed alongside the standard Cura) can be found at https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0 Sorry, only Windows and Linux are currently supported.

    +1 to the sidebar creator. The original UI was perfect in it's simplicity and functionality IMHO. The new one seems to be different for the sake of being different, and takes away space. This sidebar plugin is fantastic!

    Could a Z-hop be added on the first layer to the first extrusion point for both extruders and travels to the material change position? This would eliminate any risk of scratching in the larger movement area.

    It's not that hard to disable the perspective, all we have to do is re-implement the zoom bit. It's on the back log. I've direct all the requests I've seen about it to our product owner, but in the end, it's up to him to give it a high priority (or not of course).

    I did some tests with bed leveling before, during and after I heated the bed and nozzle and the differences where inside the margin of error that the bltouch produces even when I do two measurements right after each other when the bed is cold. I have a glass bed, I think the thermal expansion coefficient of glass is fairly small. I did a calculation: A glass bed of 5mm thickness would expand to 5.0012mm when heated from 20C to 60C 😎

    From the Cura source code: /*! * Outer polygons should be counter-clockwise, * inner hole polygons should be clockwise. * (When negative X is to the left and negative Y is downward.) */

    Installing 5.1.8 on the UM3 might brick your printer!!!! Don't try this. We are working hard to get the UM3 update working but this takes time to get stable for all situations.

    Nope, what you say is true and that's really why the sharpest corner z-seam strategy doesn't make sense for models that have corners that cannot be distinguished by their sharpness. Where it is useful is for an object that has mostly smooth curves and also an edge that runs vertically up the model and that's where you want the z-seam to be because it will be best hidden.

    The UM3 is still supported, don't worry. As mentioned above, the S5 and UM3 share a common code base and we did plan to release a new UM3 together with the 5.1 release for the S5. However ... There are more technical problems than we anticipated and the UM3 release did not pass our quality tests. The S5 with its graphical interface uses more disk space and this required another partitioning of the internal file system. Converting the existing UM3's to the new disk partition sizes is working, but we keep finding new edge cases that have to be covered as well. We are working hard to get a UM3 release out, but only want to release it when we are confident the update won't brick your printer.

    Amazing 🙂 Have you used a special fabric? I think it must be very thin?

    Used it as a large bore nozzle to compliment my AA 0.8. Really any materials would have sufficed so I left it up to people to arrive at their own conclusions. In this case, PLA. Edfit: What was accomplished was the use of the CC core as a large bore for other materials other than what UM has set it for. Oh yeah, and it does work in the UM3E even though it is listed as 'incompatible.'

    I was also going to suggest heat gunning the edges, before I read your last line above. :-) When making dental models 10 years ago, I also used a small but very hot heat gun for smoothing the edges. The trick was to apply *a lot of heat for only a very short time*, so a thin outer layer would melt immediately. But the heat would not be enough to distribute to the inside and melt the whole model. I used a gas burner heat gun with catalytic combustion (=producing just heat but no flame, due to a platinum catalyst), which could easily reach 600°C and more. It took a bit of getting used too: apply the heat for too long from a too big distance, and the whole thing would deform. Apply it from a too short distance, and it would burn and get brown or black, and start to cook and bubble. Apply not enough heat, and then you had to wait too long for any effect, so the heat would get inside, and the whole model would deform too. The balance was critical.

    Steps: The filament sensor stops printing This means it is either jammed or out of material If jammed, clear jam If out of material: go to material section of S5 commands Choose the material (not the core) It will only present change in this configuration Select change. Follow prompts. It will unload material. Material sensor is before the material feeder wheel and will be able to back out unless really ground down. After unloading material it will prompt you to put on new material and proceed when it is inserted.

    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.
