    Hi all. I'm a electronics and racing enthusiast and i had a go at "trying" to build a pretty much 100% Diy motion rig.
    Sorry for my poor English and photo taking skills..

    My original idea was to build stepper motor driven actuators but.. That was a bit harder than i expected haha. Mainly because i was trying to make the steppers hold a position with a simple analog pot.. Bad idea i know now haha..

    So back to the drawing board and i came up with a kind of overkill but sturdy design for the actuators.
    Mind you i don't have welding equipment nor any real metal working tools so i did everything with a 3d printer and a few simple tools. IMG-20190730-WA0000.jpeg

    Thinking a simple acme rod would be enough to push roughly 50kg hahah... Nope can't do..
    So i ordered these

    Then it was time for the electronics...
    I started out actually trying to design and build my own H bridges and although they worked fine it was way overcomplicated and overbuild..

    So after almost frying my psu i went with a more compact and simpler solution haha.

    Also tried to find a cheap and fast dc motor and i had a battery powered angle grinder laying around and it had a pretty beefy 18v very fast dc motor in it. So I bought another one and thats how i sourced my motors ^^

    This is where i am atm. The frame...
    Tomorrow i will post my progress from today.
    Hope you guys enjoy my rookie mistakes and poor craftsmanship ^^

    Did some full weight testing just now and damn what power is in those tiny motors!
    At first i was afraid that they lack torque as they're made for speed but boy was i wrong!
    Also i figured the weight of me and the rig itself was enough to keep the actuators from lifting out of the sockets/feet but they definitely need some reinforcement asap!
    Now i need to figure out a way to permanently link them to floor so they don't lift up anymore...
    Also the belts are quite noisy.. Any ideas how to silence them?

    Ps: Funfact. The belts are from a old broken (mainboard) T300 :rolleyes:

    Had some issues with the position pots slipping out of sync.

    So i made a little notch in the axle and printed a better version.
