Hi Guys,

I got an ultimaker 2 and have some problems printing out objects. Maybe somebody could help me, I got some problems with infill.

The infill doesnt look like it should. Its only vertical lines (but they are printed clearly) instead of a mesh

This is a picture how the infill should look (cura)

Here is a screenshot how it looks when printing:

This problem occurs in lots of prints.

Im using Cura 15.02.1 (Printer firmware 14.x)

printing at 2mm³/sec - pla 210 degrees about 50mm/sec

Infill 25 % same speed as rest of the print

The outside object surface is very good

I cannot find anything on the internet about this problem. (The other premade models from SD-Card print its infill correctly ) It occurs on lots of objects i want to print with Cura

    Try lowering infill to 24% or lower. The pattern changes when you go over 24%. Go into layer view and look at the infill at an angle while zoomed in, then step through the layers. You'll see what I mean when you go back and forth between 24% and 25%.

    Thank you for this quick answear.

    I notice, that the grid is going from 24 to 25 % much closer together. 24 % got a much bigger mesh.

    I will try it with my next print and tell if it worked.

    It's not just the size of the grid, it's how it's being laid down. Under 24% both directions are laid down at the same layer. Over 24% and only one direction is laid down on each layer. So on layer n you get lines going up and to the right, on layer n+1 you get lines going up and to the left, rinse repeat.

    If it aint broke, don't fix it? If the firmware is working well for your needs there is no reason to update the firmware. Especially since we've seen bugs creep into the firmware quite often lately.

      • Here it is. The new UltiMaker S7
        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 🎄
        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.
