Extrusion du filament avec Octoprint petite question

Posted · Extrusion du filament avec Octoprint petite question

Bonjour lorsqu'on lance habituellement une impression standard avec une ultimaker, après que la température de la buse soit bonne, un peut de filament est expulsé avant de commencer l'impression, les brims sont alors propres.

J'utilise Octoprint pour lancer une première impression depuis ce matin et j'ai remarqué qu'il n'expulsait pas de filament avant de démarrer l'impression, la buse chauffe et commence l'impression ce qui laisse un brin presque transparent pour la première couche.

Est ce que c'est normal ? Merci à vous, j'aimerait trouver le bon réglage avant de commencer un print plus conséquent.

    Merci mais je n'ai encore jamais édité de Gcode. Il faut donc mettre cette valeur au début:

    G28 ; home all axes

    G1 X110 Y45 F3000 ; bring extruder to the front

    G92 E0 ; zero the extruded length

    G1 Z30 ; lower

    G1 E50 F225 ; purge nozzle with 50mm of filament

    G1 X80 Y60 F3000 ; move aside of the puddle of primed plastic

    G92 E0 ; zero the extruded length again

    et à la fin:

    G28 ; home all

    M104 S0 ; turn off heaters

    M140 S0 ; turn off bed

    M84 ; disable motors

    Comment il faut faire pour rentrer ces valeurs ? Je suis une vraie quiche

    Quelqu'un sait comment ajouter une phase "d'attente" quand j’atteins ma température de consigne ?

    Par exemple : Je veux que me buse chauffe à 220°C, quand elle est à 220°C, j'attends 3 minutes avant de lancer le print

    Merci :)

    edit : je dois utiliser cette commande, nan ?

    Merci c'est plus clair. Le code est bon ? Je peux l'utiliser en l'état ?

    Pourquoi attendre 3 minutes avec la buse chaude? D'après moi ça ne peut que t'amener des soucis... (filament qui se carbonise à l'intérieure de la buse)

      • 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.
