    So if I understand correctly, will I create the file like the one I have attached?
    Then in AC I modify the file: ff_post_process.ini adding this string:
    [HEADER]
    VERSION = 1
    TYPE = LUT
    ENABLED = 1
    [RANGE]
    VALUE = 1
    [LUT]
    CURVE = myfile.lut
    is subject to changes right? Sorry but I'm not very practical. Thanks

    Yeh looks good to me. I've made a change to the suggested lut settings on the previous post as there was an error.

    OK thank you.
    The correct ones are these with the addition of space between ENABLED = 1 and [RANGE] then between
    VALUE = 1 and [LUT] Right?
    ===========================
    [HEADER]
    VERSION = 1
    TYPE = LUT
    ENABLED = 1

    [RANGE]
    VALUE = 1

    [LUT]
    CURVE = myfile.lut
    ===========================

    Yeh just keep the same formatting as the ini file. I don't have AC installed so I can't see it for myself.

    Hello lads , I'm working towards building a FFB wheel , but somehow I'm stuck at "creating" the FFB .
    I've followed EbolzMagy's steps , using the next items :
    - Arduino Leonardo
    - BTS 7960 43A Motor Driver
    - 12v Power Suppy
    - Yumo E6B2-CWZ3E Encoder
    - 12V D.C Geared Motor
    -3x10k Potentio

    I've connected everything exactly as EbolzMagy presented in his videos , but I can't seem to get any feedback from the motor , actually I don't get curent on the motor from the driver .

    Any solutions towards this problem ?

    Thanks

    It might be a pretty broad bunch of reasons...what soft are you in? Ebolz have several videos for different soft. People sometimes tend to mess them.
    Just as a start.

    I've been following his " DIY arduino forcefeedback steering wheel " Part 1 to 4 , basically his first videos on the channel

    And that's exactly with Aiwave tool. Not the EMC. Aiwave is.... better even not to discuss it. Download at least his EMC Lite soft and watch for connections.

    I've tried his EMC tutorial , did everything the way he presented , still no FFB . When I open EMC software , I get the Steering Angle shown , but there's no power delivered to the motor . Can the BTS 7960 be faulty ?

    I saw even "faulty" encoders, connected in a crazy way meanwhile... Hard to say according to only words etc

    Besides other things, can suggest removal of the bts radiator, and test them again. But carefully. If that help, chips've got short circuit throught the radiator.

    It kinda worked(works with the radiator on as well) . Now when I get to test the FFB in the "iRacing Force Feedback Test" , no matter which option I get , it spins my wheel endlessly on one direction . Any reason behind that ? How can I solve this problem.

    Swap the polarity on motor. Or pwm pins. Its all the same.
