    Welcome to all of you I am new to the forum
    I have a problem I don't know what caused it
    I connected the motors to make the Simulator Racing Car
    I connected the wires as in the attached picture and I did a test of the movement of the motors manually with SimTools and they work properly but the problem when running the games is that the motors do not work!!

    A friend told me that you have to buy game add-ons for the motors to work, is that true? Is there a game add-on to run the motors as a free trial only?

    And thank you all

    We will need far more specific information and pictures of your actual settings.

    From the picture posted it seems likely that you may be using SMC3 with IBT2s, is that the case and if so with what motors and please post pictures of SMC3 running the Sine test?

    SMC3, or whatever control hardware/software used, needs to be properly configured before using SimTools.

    Once the control side is working as expected please post pictures of all SimTools settings.

    You state that SimTools is working and if so I expect that would be in Output Testing, but Axis Assignments are required to be properly configured for each game, please consult the SimTools manual and the profile setting tips in the FAQs: https://www.xsimulator.net/community/faq/simtools-settings-tips-and-tricks.18/category

    If using a licensed version of SimTools v3 it has a new repository system with plugins included.

    The unlicensed demo version of SimTools has the fully function plugin included for Live For Speed, specifically for testing purposes. LFS must be run in first person race before being patched for motion: https://www.xsimulator.net/communit...run-in-first-person-mode-before-patching.365/

    I'm using a free, unpaid version
    I tried Live for Speed and the motors didn't spin, knowing that they spin using Axis Testing Dof Output

    Please post a picture of SMC3 running the Sine test, as requested, so we have some idea as to how that hardware is behaving.

    As already advised LFS must be run in first person race before being patched for motion: https://www.xsimulator.net/communit...run-in-first-person-mode-before-patching.365/

    Unpatch LFS, run it as per the FAQs, then repatch making sure it is the correct directory, and then configure correctly, please see the manual: https://www.xsimulator.net/community/faq/rtfm-start-with-the-official-simtools-documentation.117/

    And the Tuning Tips: https://www.xsimulator.net/community/faq/steps-to-create-a-motion-profile.228/

    The Dir setting as currently set do not look right, please see the FAQs here: https://www.xsimulator.net/community/faq/which-way-to-set-simtool-axis-movements.230/

    The allocation % are too high in Axis Assignments: https://www.xsimulator.net/community/faq/axis-assignment-percentage-totals.120/

    As an aside, as you are just getting started it would make more sense to use SimTools v3, and it will be cheaper for you as well: https://www.xsimulator.net/community/faq/simtools-v3.401/

    This is a bicycle motor, what are the software settings for him?

    Please see the earlier suggestions, posting a picture of the hardware running a SMC3 Sine test will tell us more about the hardware characteristics than pictures of motors, and an outline of their specs.

    It may seem pedantic, but the previous requests for specific information are not critical, rather it is all about trying to understand what hardware/software is being used, the associated settings, and applying a first principle approach to troubleshooting.

    For example, IBT2s, based on feedback from other members, is that they need to be run at less than 24v for reliability reasons, and even aside from that, they should be tested in terms of actual functionality, as some have reported faults with even brand new units.
