voici une impression un peu plus important en taille 125x95x20 que ce que j'ai fais jusqu'alors.

si les experts du forum peuvent me debriefer :)

les parametres:

matiere:ngen buse=230°c plateau=85°c ventil:30% remplissage 20%

1ere couche=0.26 couche suivante=0.20 retrait=1.5

l'impression est correcte sur le dessous et les cotes et la tenue mécanique est correcte aussi:

par contre : j'ai des défauts:

-les couches supérieurs sont pas top (jointure)

-il y a des cheveux

- le pont s’écroule

- au début de l'impression la buse "racle" un peu de matière

- lors de l'impression des périmètres il y a de légère vibration au niveau du plateau, un peu comme si la buse touchait les hachurees du remplissage

    Bonjour @droj

    Épaisseurs dessus/dessous tu es a combien?

    Les vibrations indiquent que ton plateau est mal calibré, dans ton cas la buse n'est pas assez proche du plateau.

    Pour le ngen, je suis plutôt a 235° temp d'extrusion, plateau 75°.

    Tu ne nous donnes pas tes vitesses d'impression...

    oups je suis pas complet, voici la suite

    vitesse 1er couche: 30 remplissage 60 top/bottom 30 coque 40

    epaisseur 1ere couche 0.26, ep couche 0.2

    ep top/bottom=0.4 (soit 2couches de remplissage)

    ep coque= 1.2

    je vais recalibrer @duriel

    voili voilou

    Épaisseur de couche dessus/dessous (top/bottom) essaies plutôt 0.8 mm

    réduis peut être aussi la vitesse top/bottom a 20 mm/s

    bon voila un 2eme essai, j'ai retouché legerement le designe

    par contre je me pose la question

    si on met 20mm/s dans l'onglet "simple"

    cura en tient il compte dans l'onglet "avancé" ?

    les parametres:

    layer_height = 0.2

    wall_thickness = 1.2

    retraction_enable = True

    solid_layer_thickness = 1.2

    fill_density = 20

    print_speed = 25

    print_temperature = 235

    print_bed_temperature = 85

    support = None

    platform_adhesion = None

    filament_diameter = 2.85

    filament_flow = 100.0

    nozzle_size = 0.4

    retraction_speed = 40.0

    retraction_amount = 4.5

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • 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 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.
