Posted · Cura Version Bottom Layers Poor Quality

Hello everybody.

 

It's the first time I'm writting in this forum so let me Introduce myself a bit. I use 3D printing mainly at work, we have a Ultimaker 3 Extended to print prototypes. 99% of our print are made in grey PLA and we normally use either PVA or Breakaway as supports. Lately I've been having issues with the the bottom layers, not the intial layer, all the bottom layer sin contact with the supports. I've tryed many things, touching temperature, velocities, overflows, material,... all kinds of setting but at the end I was having the same results.

Today I was thinking about it and I did a change, I downloaded the version 3.6 of cura and I've printed with the exact same settings, materials and printer and magically the problem has gone away!

Does anyone know why? There is anything I can do in Cura 4.4 to print as good as cura 3.6?

 

I attach a picture with both prints.

Thank you veru much!

    Hey,

     

    are you sure you have the newest version of Cura installed? There was a bug with the "stair stepping" as mentioned here: https://github.com/Ultimaker/Cura/issues/7018 I don't know if it was fixed in Cura 4.4.1.

     

    Maybe you can check if the problematic layers were supported enough. Was this part printed with PLA and Breakaway? I had a similar looking issue and the suggested workaround solved the issue.

      • Here it is. The new UltiMaker S7

        Here it is. The new UltiMaker S7

        MariMakes posted a topic in Official news,

        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
         
         
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
         
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
         
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
         

         
        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄

        Cura 5.3 Alpha With New Tree Support 🎄

        MariMakes posted a topic in Ultimaker Cura,

        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
         
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
