Hey everybody!

I am having some issues with my print.

Do you have some suggestions what to do in order to get a clean print ?

These are my settings. I print with PLA 2.85 at temp 190 degrees.

Thank you in advance for some suggestions.

    you need to show your speeds and layer heights.

    Also retraction lengths etc.

    It looks like hairs or very thin strands. this maybe because you are printing to cold for that material. It looks like you have lines not touching on the base which also points to temp to low.

    Dear Labern,

    The layer height is 0.1 and speed 100 mm/s.

    The retraction length 4.5 mm and speed 25 mm/s

    I changed the temp because at 190 it is less hairy.

    Thanks in advance for more suggestions.

    That is way to cold for that speed. You should be printing at 30mm/s at that temp.

    100mm/s is very fast. It's ok to print at that speed but you need to be a lot hotter and quality won't be that great.

    I see your minimum extrusion is .02mm - that's of 2.85mm diameter filament. That might be too large - it might not be retracting - so first thing to check is to look at those towers in layer view. Retraction is shown as a vertical blue line. If you have vertical blue lines leaving every tower then the .02mm is fine. If not lower that but beware that too many retractions (e.g. 100 retractions on the same spot on the filament) can grind down the filament to dust and cause failures.

    The other thing is that this is white filament. White filament makes strings like this more than any other color. It doesn't seem to matter who the manufacturer is.

    also 100 mm/sec is going to cause more stringing. This is because you have higher pressures in the nozzle. I recommend maybe 35mm/sec for these towers with 200mm/sec move speed between towers.

    But of all the recommendations - the most important is use a different color.

      • 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.
