    Ok, i am finished. My 2dof performs perfect (for me) in LFS. For now i have Surge + Sway on 100 %
    and Heave on 50 %.

    I had to reverse Axis1a. Now in LFS breaking goes up and speed goes down.
    Also vibration on curbs. But just a little bit.

    As soon as my seat is here i will put in on and then i think i will make some fine tuning on it.

    Great. This Forum and his members are great! Realy.

    I am very gratefull for all the help i get here.

    BTW - If anything is realy finished and working i am going to make a 3rd axis for drift.

    Will try another wiper motor and put a T16 Rod with basement on it. Maybe it is fast enough
    to give drift feeling.

    I made a video but i have no Youtube channel to upload....not yet :) But i will and paste
    Link in here.

    For now this is my nearly finished Sim! Tommorow i will do the rest work on it.

    Be careful with Axis Allocations, the total should be around 100%, not 100% per DOF, see here for details: https://www.xsimulator.net/community/faq/axis-assignment-percentage-totals.120/

    The normal convention on a 2DOF is to pitch down (surge) on braking and pitch up under accelerator, this is what SimTools expects: https://www.xsimulator.net/community/faq/which-way-to-set-simtool-axis-movements.230/

    Your pending video will help members give further tuning advice.

    Now that you are getting to tuning grab a a copy of the Simools manual and keep it handy for reference: https://www.xsimulator.net/community/faq/rtfm-start-with-the-official-simtools-documentation.117/

    There are also handy FAQ tuning tips here: https://www.xsimulator.net/community/faq/steps-to-create-a-motion-profile.228/

    Ok, i have now put all to this

    endset.jpg

    seems to work fine.

    Should i also post my 3d printed parts in here or in the 3d print section?

    The parts regarding to this sim build. So i am not sure where to put them.

    greets

    Do you have pictures of your rig and details of the build process?

    Yes, will get my Seat end of the week, i will mount it and make a Video of the whole Seat with the simrig.

    I will also add pictures of the finished rig and the STL files of the POT mounts for interessted people.

    Sorry had a lot to do @work and @home atm.

    Just checking if you have finalised your rig yet and if you can share some pictures of it?

    Hi Noorbeast

    yes i did have finished my Seat. But i have a couple of problems to solve.

    First of all my motors seems to have not enough power and the second issue is that i am
    thinking that the middle point of the weight of my construction is wrong.

    I am falling to the front if i sit on the seat. But if i am putting it to far back the motors
    do not have enough torque to hold.

    BUT! I am actually building an actuator for testing purposes. I am leaning on the conception
    of the SFX Plattform. But i try to make it as a cheaper version for everyone.

    I am still testing on 100x100 aluminum profile but i will go down to 80x80 to reduce cost.

    As i have plenty of work i do not have the time to focus on this. But i will find a solution.

    I am using a regular Nema 23 with 3.0 nm. I know that this would not able to hold large
    weights, but it is just for testing its function. If it works i will try 34 or higher nema stepper.
    Position Feedback will be given over a 100mm fader. Maybe it will work.

    Right now i am waiting for couplers coming from china. Cost per coupler 3.50 Euro from China
    from Germany 25 Euro. So i decided to wait :)

    But now wait a few mins. Pictures from my seat are coming.
