Retraction Problem?

Hallo,

ich bin Stephan und habe seit ein paar Wochen den Ultimaker 2. Bisher hat er mir stets super Ergebnisse geliefert. Nun habe ich jedoch ein Problem, dazu habe ich ein Video aufgenommen.

Der Ultimaker soll 4 Kreise drucken und zieht nach dem Kreis Filamentrückstände mit sich bzw. bei den Kreisen auf der rechten Seite kräuselt sich das Filament beim drucken. Habe bereits die Travelspeed auf 100mm/s reduziert (siehe Video) aber es hat sich nichts geändert. Ich vermute, dass es sich um ein Retraction Problem handelt.

Druckgeschwindigkeit im ersten Layer sind 20mm/s. Als Filament dient das Original Filament von Ultimaker das ich bei 210°C drucke.

Wenn mir jemand Lösungsvorschläge geben kann, wäre ich sehr dankbar.

Viele Grüße aus Aachen

Stephan

    Die Druckgeschwindigkeit im ersten Layer ist auf 20mm/s eingestellt. Habe es in Cura sowie manuell im G-Code überprüft.

    I have printed the first layer with 20mm/s. Checked it in Cura and the G-Code.

    schau mal in Cura in den Expert Settings (STRG + E) nach ob bei "enable combing" ein Haken gesetzt ist.

    Falls ja dann wäre das normal, denn mit gesetztem Haken unterlässt der Drucker die Retraction wenn beim "reisen" der Druckkopf keine nicht zu bedruckende Stelle überfährt.

    Falls nein dann eventuell mal die Retraction Weite erhöhen (ca .5mm)

     

    EDIT: schau mal während des Drucks hinten auf den Feeder ob er wirklich die Retraction durchführt...

     

    Haken war gesetzt, habe ihn jetzt für den Druck weggenommen und es klappt nun alles! Vielen Dank! Empfiehlt es sich die Funktion auf Dauer deaktiviert zu lassen?

      • 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.
