    Hello,
    First thanks for all the usefull information on this forum.

    After a lot reading, watching, testing, programming (not real programming ;)) and collecting materials i am ready to start the build of a real Motion Simulator.

    First tested on a scale model 3DOF (Roll, Pitch and Yaw) balancing on a balljoint using a Arduino Uno and some RC-servo's

    The testproject was working fine but the Real Sim will be first 3DOF (R, P an S) with a option to 4 DOF (R, P, H and S), i think the Sway function is more usefull for racing and i like the optional Heave function for a more realistic VR experience.

    For the simulator i use aluminium constrution profiles size 45x90mm and 45x45mm, motors and controll is still a big
    ? I have experience with all techniques (AC worm, frequency convertors, DC brushed/brushless, stepper, lineair etc. its all about price/performance/noise.

    Update soon, tomorrow start working on a solid joint

    Stay healthy.

    Planning for today, a solid joint.

    This is a part from a old optical polisher i think it will do the job.

    Job done, the whole centerjoint and sliding system is works smoothly without any play.
    Until now i am very satisfied with the result, now it is waiting for a sports seat and some 24v DC wormgear motors for testing (only 35watt). Everything is rather delayed by the whole virus problem.

    Thanks #dedas i enjoy this project a lot :)

    Today i run in to some geared AC motors, in my opinion the are strong enouch for a 3DOF with centerjoint, please shoot if iam wrong :think i have not purchased them yet

    To continue with the rig design i am still waiting for the sportseat, it is lost for a week now :(

    Stay healty
