    Hi, month ago I decided to build my own motion platform. I was looking for information how to build it and found xsimulator forum and D Max on Youtube. I want to create something like this:



    So far I made a 3D model and I'm gathering parts. I want to do DIY FFB steering wheel too. I want to use arduino for motion platform and stm32 for steering wheel. It will be an interesting summer. :)

    So far so good. I welded 3 frames and finished belt FFB steering wheel. Now it's time for wiring everything up. I hope BTS7960 will work with 24v 350W motors. Seat I used is testing purpose only, if everything will work, then I will buy bucket seat.

    I tested driving position and it is just right. Unfortunately 3D printed quick release system from my old ffb steering wheel failed. Old one had 100W motor, now it is 24v 350W. 287125365_1445770232542939_4853476770866885543_n.jpg

    I designed 3D model with m8 screw reinforcement . I hope this time it will last longer, otherwise I will buy normal quick relese like in real cars. Tomorrow I will print and test it.

    New quick release is ready. Connection is really tight, but easy to unconnect with bike seat clamp. I'm satisfied with this part.

    Next I'm going to do cooling and control box.

    I drilled holes in box and mounting plate for better cooling. I will use two 24V fans for cooling.

    Power supplies, relays and fans on place. Next step: more radiator, thermal paste for IBT-2 modules and WIRING! :)

    Wiring for first BTS almost done. I need to repeat this process two times, but I enoy it :).

    Power line wired up. Arduino wiring and BTS->motors left.
    Here is my wiring diagram for Emergency Stop:

    I have Arduino NANO so I will use it, because it is the same microprocessor like in UNO just smaller pcb. I soldered board for wiring with jumper wires.

    Everything wiried up :). First test done, 3 motors running in good direction. I'm getting close to first motion test .

    Motor 1 and 2 have 25kHz frequancy, but Motor 3 has got only 4kHz and 31kHz option. BTS7960 is up to 25kHz. Can I set some how 25kHz on motor 3 as well?

    Motor was overheating too fast, so I had to use shorter arm. Now it's ok I think.

    I'm after first "ride", looks promising. I have to tweak setting, but overall I'm getting somewhere.

    Great to see your rig in action, well done :thumbs

    Just some suggestions, it looks like sway needs tweaking, it should lean away from a corner, and roll gets set the opposite of sway. Some heave would also add to the immersion.

    I think I have driveable settings for now. Surge is jerky, but I think it is because I used keyboard so far. In next test I want to use steering wheel and VR.

    Excellent progress :thumbs

    I agree, the surge axis allocation looks overdone, perhaps a smaller Axis Allocation % and smaller Tuning Center values would tighten surge up, see the FAQs re snappy gear changes: https://www.xsimulator.net/community/faq/snappy-gear-change-motion.121/

    the chassis for the loss of traction is well thought out and the skateboard wheels are really well seen:thumbs

    Thanks :), few days ago I started to use traction loss and it is awesome. Just need some tweaking.
