Posted · modification firmware visiblement pas prise en compte

bonjour, je viens de finir le projet de montage d'une ultimaker 2 faite maison avec pas mal d'améliorations vs les plans d'origine

le moteur de l'axe Z n'a pas la bonne course (la moitiée je pense) par rapport au moteur original monté sur les versions du commerce

je cherche donc a modifier la valeur de step par axe pour l'axe Z

j'utilise arduino pour modifier le firmware pris la base de donnée suivante


je modifie cette ligne de code dans l'onglet configuration.h du logiciel arduino

#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,200,282}

je vérifie, je compil et je transfert (televerse) port com 8....

l'ultimaker 2 s'éteind et se rallume ce qui me confirme la fin du transfert je pense?

je teste en manuel les déplacements avec le JOG de repetier et printrun mais rien ne change malgrès des tests avec des grandes valeurs opposées

j'ai tester pour Z de 20 jusqu'a 4000steps

j'ai testé sur un autre axe idem

j'ai testé en envoyant le firmware "Marlin.cpp.hex" via cura idem

la je sèche.... je pense avoir tout bon mais visiblement c'est pas le cas

quelqu'un aurait-il une idée car je suis plus mécano qu'automaticien

je pense que ces valeurs son réécrites quelque part ou que ma méthode n'est pas bonne

merci d'avance a vous tous

    2-3 choses...

    - Tu peux tester sans recompiler de firmware avec la commande M92 dans repetier -- ex: M92 Z100

    - Je ne connais pas les menus de l'UM2, mais sur l'UMO tu peux ajuster aussi ses valeurs via le menu

    - Les steps per units sont sauvés dans la nvram, si tu les changes dans le firmware il faut ré-initialiser la nvram, sinon on garde les anciennes valeurs. Il doit y avoir un option (genre 'restore defaults') dans le menu pour remettre dans la nvram les paramètres définis dans le firmware.

    bonjour, je suis novice dans ce domaine, je vais tenter la commande dans repetier

    j'ai un "reset factory" dans les menus de l'utimaker je vais tenter cela

    bonsoir, merci cela fonctionne c'était bien ce petit truc qu'il me manquais, je vous remercie beaucoup j'ai pu enfin tester mes premières pièce et effctuer mes premiers réglage

    encore merci

      • 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.
