    My Motion Simulator:
    Arduino, 6DOF
    No sure whether I should put this here as it is NOT yet a full size 6DOF, but it is the first step to it.
    I just wanted to share my work that can be usefull for someone who have a 6DOF but don't feel confident enough to jump into it. This should build your confidence :)

    My goal was to design a small 6DOF stewart platform scale model made of cheap RC servos to make sure I understand how it works. I had an Arduino Uno already, and simply printed a few parts with my 3D printer (I can share the files later here) and some RC helicopter rods and ball joints.

    I used simtools 2.2.5 which comes with a demo mode, and a pluging to connect LSF. LSF can also be downloaded here for free: https://www.lfs.net/

    Now, if you don't want to invest a cent in building a scale model of a 6DOF platform, I suggest you use sketchup and it's pluging SketchyPhysics to see the results in real time. I followed the procedure here https://www.xsimulator.net/community/faq/how-to-animate-sketchup-3d-model-with-simtools.209/
    Here is an important tip however: Do NOT make your model too small. SketchyPhysics will NOT render any physics on small objects. I understood it the hard, since my scale model is very small, and waste 2 days in trying to understand why the software was not behaving the way I wanted. Other you can simply use my model with the configuration I'll be sharing here.
    Here you can see a short video of the results. Both real 6DOF scale model and the virtual one behave the same way while playing with LSF. Next step is a test with X-Plane 11, my goal.
