    I bought over / was given by my friend a seat mover:

    This is my current racing rig :

    I would like to integrate and improve / upgrade the seat mover with additional traction motion (3 axis) into my Rig.

    My Motion Simulator:
    DC motor
    What I am trying to achieve :
    3 Dof Simulator hopefully Similar to Simxperience stage 4 .
    (I am not looking for extreme movement, just looking for quick and precise/ small movement feedback for Iracing & AC .)

    Problem I am facing :
    1. Gearbox with a lot of free play
    Solution : Use Shims (Read it from Nick Moxley thread)
    2. Change of potential meter and Change the location of potential meter
    Solution : not known yet
    3. Reduce the seat height of the current seat mover
    Solution : not known yet
    4. Change position of the Motor
    Solution : not know yet
    5. Add the 3rd DOF
    Solution : not known yet




    It will be great if anyone can help and advice me =)

    Thanks

    Here is some existing traction loss information: http://www.xsimulator.net/community/faq/traction-loss.174/

    As traction loss involves a top and bottom frame you may want to consider cannibalizing your existing compact simulator for parts and converting it into a shoulder mount frame design.

    You could use Hall sensors instead of pots and mount them directly to the motor shaft with a flexible coupling: http://www.xsimulator.net/community/faq/how-to-connect-protect-a-potentiometer.13/

    Have a slight amount of forward weight pre-load on the motors and replace the rose joints with tie rod ends should help with the play, though there will always be some with wormdrive gearboxes.

    Hi noorbeast , thank you for your prompt reply.
    I will read up on it tonight

    I am planning to convert it to a shoulder mount frame design.
    For sure I have to cannibalising and make use of everything thing I have currently

    Hello Guys

    I am in the midst of building a base platform.
    By any chance could you guys share with me how many degrees of yaw do you usually have on 3 Dof Traction loss simulator ?

    I have 420mm of movement at the back wheels, I haven't converted that in to degrees. I think I could go up to around 500mm but 420mm already is tons. As Noorbeast said, most rigs are 200-300mm

    @avenga Nice rig you have there...
    Your changeable length lever is really cool. I will try do something similar to yours.

    Hello Guys

    How do you guys secure your shafts to the worm gear box?

    Did you use the two grub screw slot? Will it be enough ?
    I am about to lathe a new shaft out.

    Thanks =)
