La BETA 2 de CURA Arachne vient de sortir
Selon le big boss grand chef du développement, cette version est plus proche d'une version finale que d'une version beta.

Pour info/rappel: ce nouveau moteur consiste en une refonte complète de la façon dont CURA slice en passant d'un mode "classique" d'extrusion avec une volume continu invariable à une extrusion dont le volume varie en fonction de la situation rencontrée afin d'impacter la largeur du mur à créer.

Concrètement et pour faire simple, les slicers commencent le calcul par le mur extérieur puis ajoutent les murs intérieurs et enfin terminent par le remplissage et ça fonctionne dans la plupart des cas : d'ailleurs, tous les slicers font comme cela...

Mais prenons un exemple : l'objet que vous souhaitez imprimer a des parois qui font 1 mm et vous avez une buse de 0.4 mm il restera 0.2 mm à combler (2x 0.4 - 1 = 0.2)
Arachne va faire son calcul mais en partant du milieu (et plus de l'extérieur) et va générer un "squelette" de lignes centrales puis va calculer le nombre de ligne qui peuvent être contenues dans chaque zone et comment il peut les combiner.
Il peut alors décider d'utiliser 3x 0.333 mm d'extrusion pour remplir cette zone de 1 mm au lieu de 2x 0.4 + 0.2 mm.

Bref, ça change tout et notamment dans l'adaptation du dessin souvent nécessaire dans l'épaisseurs des parois au moment de la modélisation des objets afin de les rendre "imprimables" : que celui qui n'a pas utilisé sa calculatrice pour déterminer le nombre de murs afin d'obtenir la bonne épaisseur en fonction du diamètre de la buse me jette la première bobine de PLA.

Pour avoir tester la beta précédente qui marchait déjà bien, j'avoue que le résultat est vraiment intéressant.
Attention quand même à la bonne tenue du cheminement du filament Bobine > Feeder > Tête afin de bien gérer le volume de filament à extruder qui va varier en continu mais ouais, c'est vraiment quelque-chose qui va simplifier les aller/retour CAO > CURA > CAO > CURA

      • 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.
