  1. Hello, thank you for your message. How hot is too hot? 60ºC for the bed and 190ºC for the nozzle with PLA doesn't sound too hot. If it helps, perhaps you could attach a picture illustrating the problem you are observing. Thanks

  2. Hi, 

     

    Thank you for your comments and sharing your experience. A small offset can be expected, depending on the material, size of your print or other custom configurations you might be able to influence the accuracy slightly.

    I do believe that I with a square part I should get better matching results (.35 mm over 50mm).

     

    I believe that too, it sounds like it might not operating to its fullest capabilities. 

  3. Hello everyone, 

     

    We don't often release an alpha version of Ultimaker Cura... So what's different this time? 

    Well, this Ultimaker Cura alpha contains such a huge slicing engine overhaul that we really need your help! We want to give users the chance to test this early release as soon as possible. Your feedback is vital to help us release the very best stable version of Ultimaker Cura in 2021. 

     

    So what's the big change? 

    The Ultimaker Cura slicing algorithm is enhanced with the Arachne code library. This fundamentally changes how Ultimaker Cura handles inner parts of a model. For example, let’s say that you want to print within a space that's 4.4 mm wide. Using the current slicing engine, a constant 1 mm line width could leave a 0.4 mm gap that would be tricky to fill. 

    Instead, Arachne adds variable line width to the slicing algorithm. That could mean printing 1.1 mm across all four lines to ensure good fill and prevent the 0.4 mm gap. 

     
    In this way, the we intend the upgraded slicing engine to optimize line positioning and variable line widths – especially for thin walls and around corners. 
     
    This should result in: 

    • Better handling of thin walls and filled gaps  
    • Smooth line transitions inside tapered geometries  
    • General print quality and strength enhancements  
    • Reduced print head movement for filling in gaps 

     

    124538720_arachne1.thumb.jpg.0f80d1a3c0cf309d25ca58d5f082bd8a.jpg

     
    Which new settings need testing? 

     

    The improved Ultimaker Cura engine gives you new settings that will optimize printing thinner walls, including:  

     

    • Variable Line Strategy (3 options: Center Deviation,  Distributed, Inward distributed) 
    • Minimum variable line width
    • Wall transition length 
    • Wall transition angle 
    • Wall transition distance filter 

     

    So now you have the chance to peek into Ultimaker Cura’s future, test these settings, and see how they work for you! 

     

    If you decide to tune these settings and doing so results in better print quality, please share your findings with us. Doing so will help us set default values for both Ultimaker and third-party printers. This is particularly relevant for third-party printers, because we don't have these available for testing and updating their profiles. 

     

    How to start testing : 

    1. Download Ultimaker Cura Arachne engine alpha
    2. Run some tests with prints that you're familiar with 
    3. Consider trying a print with thin walls to test the difference 
    4. Share any feedback or bugs via GitHub. (Simply enter a bug or feature request, you'll automatically find the correct feedback template.) 

     

    Read this before you send feedback  

    During the alpha test we will keep this support article up to date with news and known bugs. Please take a look before you post a bug report. This will prevent extra work on your end and ours. 

     

    Warning! 

    Please remember that this Ultimaker Cura alpha is not suitable for ‘normal’ use. It should be only used for testing. In addition, this version represents a huge code change, so some features – like fuzzy walls – are not yet supported. There is also a higher chance that you run into a bug (some known, some unknown). These might reduce print quality. Due to the holiday season, responses from Ultimaker might be a slower than usual. 

     

    And then finally... 

     

    A HUGE thank you to anyone who can contribute to this alpha test! 

     

    We're incredibly excited about what the Ultimaker Cura engine improvements will offer the global 3D printing community. And by working together, we will be able to turn it into the best possible version for everyone. 

     

    And if you want to learn more about the framework behind the Arachne engine, you can read the scientific article it’s based on here 

     

    Have a wonderful day!

  4. Hello, 

     

    Look at what these guys made! We just launched the Ultimaker Innovators List 2020, a conclusive list of wonderful and inspiring innovations we came across! It even features some people from this community of 3D printing experts! Do you feel like getting inspired? I wrote more about the Ultimaker Innovators List here, and you can find the entire list right here

    Hello! 

     

    2020 is almost at its end, and that is usually the time to reflect upon ourselves and the world around us. Look back at all we did and were able to achieve. For all the things that might make 2020 an infamous year, there was also a lot of innovation, growth and progress we witnessed. At Ultimaker we wanted to celebrate all the innovation we’ve been blessed to come across. Not only in 2020, but also beyond. Together, this formed the foundation for the 2020 Ultimaker Innovators list.

    The Ultimaker Innovators list. 
    We wish to celebrate and honor the innovators that push forward the field, technology and world. We opted to not present it as a competition or ranked list. Every innovator has earned his spot on that list in their own way. We also look at the 3D printing industry as a whole and not limit the list to those only using Ultimaker. 

     

    How did we select this year’s list?
    For 2020’s Ultimaker Innovators list, entries were nominated by colleagues from all over Ultimaker. The final list was compiled from those nominees by Ultimaker’s Community and Content Marketing teams. Do you feel like we missed someone? You can nominate yourself or others for the 2021 list at the end of this year's list.

    Who are the Ultimaker Innovators?
    They represent a very diverse group of people, creating innovation on many different levels. Like: 

    • Innovation; Achieving new things with additive and distributed manufacturing that are beyond the industry standard
    • Impact; Benefits for customers, colleagues, and communities – in particular positive environmental and social impact
    • Inspiration; Encouraging or facilitating adoption of 3D printing and nurturing skills of others
    • Diversity; appliance of 3D printing in new areas and applications

    From architecture to manufacturing, from automotive to healthcare to art – and everywhere in between – we believe the 2020 Ultimaker Innovators list is a great way close 2020 – and start a new one.

     

    Ready to meet this year’s Ultimaker Innovators? Visit the list on the Ultimaker website and get inspired.

  6. Hi @balint, I have collected a few other things you can check to validate if it is indeed a faulty bearing creating the noise or something different:

     

    • You can check if the short belt is not too tight against the side of a pulley, probably the one in the back. If it might be pressed against it, you may try to loosen the tension on the motor slightly so you can comfortably move the belt a little bit to align it closer to the middle of the pulley. (short belt tension)
    • Is there any play on your axles, which can result in a ticking sound when parts touch when they shouldn't? (I don't think this is it, but who knows..) (pulley adjustment, these are instructions for the UM2+C, but you should be able to apply it to the UMS5 too)
    • Could the pulley on the motor might be too far up on the axles? If so, it could rub against the frame. The 'downside' of this is, that you have to entirely remove the motor from the frame to check. 

    But solely based on the sound, I still feel like it resembles what a bearing might sound like. But I/we can't stick our head in the printer to check 😉

  8. Hallo, 

     

    Als je je prints wilt verbeteren kun je misschien ook een paar foto's delen van je prints en van je printer. Er zijn verschillende experts hier die snel bepaalde dingen kunnen herkennen. 

     

    De meest voor de hand liggende reden waarom je feeder omgedraaid werkt is omdat er een firmware installatie op staat van een andere machine. Als je 100% zeker weet dat het de Ultimaker 2+ firmware is, is het ook een goed idee om wat foto's van je machine te delen. Het kan zijn dat je een Ultimaker 2 hebt, in plaats van een Ultimaker 2+ (of andersom), als je de firmware versie van de een op de ander zet, werkt je feeder andersom. Soms worden er ook Chinese copies onder de naam van Ultimaker verkocht. Als het een originele machine is, kun je doorgaans een UM2 herkennen aan een zwarte feeder, en een UM2+ aan een witte feeder. 

     

    Bedankt, 

  9. Hello all,

     

    Last Friday you may have read the news already, Ultimaker appoints a new CEO. After years of warm, friendly and strategic guidance Jos Burger will hand over the steering wheel to Jürgen von Hollen. I am happy to share that Jos will advance to the advisory board. Jürgen's leadership will go into effect on January 1st, 2021. 

     

    Jos Burger joined Ultimaker in 2014 and we've been able to transform the company from a start-up to a global player in the 3D printing industry under his guidance. Jürgen has the experience to take over from Jos and guide us to the next era. Exciting times ahead! 

     

    If you are interested to read more about what Jos and Jürgen have to say, you can find the press release here.

     

    A deep thank you to Jos, and a warm welcome to Jürgen!

    Thank you so much! This is what we (UM2+ owner) needed to know! There will not be an upgrade for our printer an we can invest the reserved money for other products.

     

    Without any intentions of keeping you on a leash, I am specifically talking about this upgrade. I can not look into the future so I do not know what will, or will not be released for our Ultimaker 2+ user base. 

  11. 1 minute ago, UbuntuBirdy said:

    Obviously it wasn't lucrative enough ...

     

    That is what I said, in a few more words. Let's not forget, Ultimaker is a company and we need to be lucrative otherwise we cease to exist. We try to do this while staying as close with our customers as possible, but that doesn't mean we can do everything. I think this forum and the community as a whole proves among other things, that we like to stay close to our customers and that we listen to them. Even our developers are directly engaged with our customers.

    So as I said and you concluded, somewhat alternative products exist and it would take a lot of resources to develop and maintain an upgrade kit. Which makes it not lucrative indeed. And the resources spend on it would be lost on other innovations. Maybe it is me, but to me that sounds like valid reasoning.

  12. Thanks everyone for contributing. I don't think anyone is denying that an affordable upgrade kit for an Ultimaker 2+ to bring it to a similar level as the Ultimaker 2+ Connect wouldn't be appreciated by its users. But I think you might be underestimating the complexities of making such an upgrade, regardless if it is hardware or mostly software. To build it and support the different Ultimaker 2 [...] variations it would generate which all need to be maintained, tested and supported with future (software/firmware) updates. So, while we do understand that it would be appreciated, we can only spend our time once (just like anyone else) and we have to be cautious what to spend it on. We estimated that we could be more impactful dedicating our time on other innovations.

     

    Also considering the fact that alternative solutions exist (like 3DprinterOS), which is indeed not an Ultimaker product, but does cover some of the functionality and I think most people who needed the connectivity weren't waiting for us to develop an upgrade kit, but used the potential of an open source product and managed to find their way.

  13. Hello! 

     

    I would like to give you a heads up that on Tuesday December 1 between 5pm and 6pm CET we'll host an 'Ask Me' event on Twitter with one of our application engineers to celebrate episode 16 from Talking Additive; 'Metal FFF and performance polymers'. Our Application engineer Andrea Ciappi will be online for at least an hour to answer questions you have regarding these filaments. Make sure to post your questions with #TalkingAdditive so we'll be able to find them, even if you send them our way prior to to the event. We'll try to answer all! 

     

    If you are interested in these materials, I recommend you first listen to our podcast which is already very helpful! You can find it here!

    Looking forward seeing you there!

  14. Just now, Pena said:

    Yes, you're correct, it's not Ultimaker ABS, I purchased the material with the printer from CA MatterHacker. I wish Matterhacker would've been honest and explained I had the option to purchase Ultimaker material

    I'm not saying it is bad filament. Ultimaker ABS can also show delamination. One brand of ABS is not necessarily the same as a different brand ABS, that is why I suggested those guidelines may not be exactly fitting for matterhackers ABS, but they might give you a direction.

     

    You should feel comfortable to use the material profile that is embedded in Cura, when you want to use  BASF Innofil3D PAHT CF15. Make sure you use a CC core though! 

     

    Ultrafuse can be really great, but difficult. We have a podcast about it which launches tomorrow, it will be published on https://www.talkingadditive.com/. I recommend you check it out tomorrow for more information on this subject! A week later we will have an AMA on twitter with a product expert familiar with UltraFuse, so you can ask him any questions you have, after listening to the episode tomorrow! 👍
