    We are 2 french friends, living in Saigon (Vietnam).
    We are very bad in mechanics, electronics and software but we are still starting our first 2DOF simulator.
    Our "road" will be long and difficult, but we thank you in advance Xsimulator and his member for all their help.
    However, we have a relative advantage :
    Here, everything is cheaper than in the West, in case of failure, we can start again several times
    Kindly

    Welcome @digitrax3d

    You have come to the right place for motion simulation software, information and support from a very active community.

    Have a look at existing member builds for ideas and inspiration, it could well help you refine what you may like to do for your own project: http://www.xsimulator.net/community/forums/diy-motion-simulator-projects.22/

    You will find the FAQ section covers some more specific topic areas, like types of simulators, designs and motors: http://www.xsimulator.net/community/faq/

    Do ask questions after getting an idea of what you would like to build, there is a lot to take in but the community is good at giving tips during planning, reviewing planned purchase lists, giving feedback and encouragement during the build and providing advice on actually sorting out motion profiles.

    Do take a moment and add yourself to the Member Map: http://www.xsimulator.net/community/memberMap/

    Good luck with your project.

    Thanks for your support messages.
    If we can find cheap parts or works to help you ... you're welcome !
    In Vietnam, it's very difficult to find linear actuators.
    We have some contact with China companies, but till now we don't yet found actuators with a minimum of 12/15 Nm.
    Therefore we will start with 24V truck wiper motors.
    First configuration:
    Assetto Corsa > Sim Tools > Arduino > Sabertooth > 24V Wipers motors

    Our first motion base (with car wiper motors):

    You will not have a lot of leverage so close to and level with the pivot point. In other words I suspect it will struggle to maintain snappy motion with weight on it.

    Try it as it is and see how it goes. Worst case you can just recycle the motors and do a shoulder mount seat shaker, as those motors would do that.

    In some rare cases wiper motors are earth isolated but most often are not, so be aware they need to be: http://www.xsimulator.net/community/faq/wiper-motor-mandatory-ground-isolation.25/

    I am looking forward to the next update.

    Thank you Noorbeast for your precious advice.
    We start completely, and it's sure that we will make many mistakes.
    This first plateform will be modified several times.
    For removing the ground contact of the wiper motors, I had already read informations.
    But before disassembling, I'm waiting to receive my driver cards.
    Moto monster card for testing with car wiper motors, and 1 Sabertooth for 24V truck motors.
    I hope this week.

    +1 avec l'avis de Noorbeast


    Voici un schémas de la cinématique souhaitable :

    [​IMG]

    L'usage de 4 ressorts, sur la course descendante seulement, diminue les efforts pour remonter la plateforme.
    En gros, ils éliminent les forces statiques, mais ne sont pas indispensables si les moteurs on suffisamment de couple et la plateforme est légère.

    Merci Momoclic pour ton aide.
    J'avais effectivement vu que certains (pas tous) mettaient des ressorts de rappel.
    Je me demandais si ces ressorts n'allaient pas faire justement l'inverse, c'est à dire, augmenter la charge lors de leur traction.
    Ici, j'ai trouvé des moteurs chinois en 24V - 100W pour 60$ l'unité, ca devrait aller, non ?

    Désolé mais ici en france 47,39 euros + le port, c'est très correct et comparable au 60$.
    Sans doute tes moteurs chinois feront l'affaire, même s'ils sont un peu moins puissant.

    Les ressorts ne sont pas obligatoires. Personnellement je pense qu'avec des moteurs peu puissants et des pignons en plastique soulager la mécanique n'a que des avantages.

    Thank you, everyone, for all your advice.
    We are still waiting for our driver cards from USA to test our configuration
    We are blocked

    I just found the specifications of IBT2 driver which is much cheaper than sabertooth.
    Is the IBT2 performs as well as the Sabertooth?
    Someone have the wiring diagram : Arduino Uno > IBT2 driver > 2 wiper motors ?
    Thanks a lot.

    Which Ard code you are using? Each code has a different wiring for the most part.

    Which code you recommend for 2 wiper motors

    You should ask which code supports IBT2...did you order the IBT2 already?

    Not yet.
    This morning going to an Arduino distributor, I discovered IBT2
    While I have already ordered Sabertooth, but they have not yet arrived.
    The IBT2 card is much cheaper.
