bonjour,

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

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
