    Ok. So I have (or I'm getting in the next few days):

    -Motors (80ZYT165... from Sunrise Motors)
    -Power supplies (Meanwell LRS-350-24)
    -Motor drivers (Cytron MD13S)
    -Hall Sensors (6127V1A180L.5FS)
    -Shunt protectors (Pololu 26.4V, 2.80OHM,15W)
    -Shaft connectors (6.35 x 8 mm)
    -Arduino Uno

    I still need:

    - An U-joint of some kind
    - Levers and rods.

    Anything else I need for the motion part?

    Have you read my thread in regard to the driver and shunt? I haven't attached cables yet. I think I will have to solder 10awg directly to the board...
    Let me know how you do/did it.

    I also have to get levers, push rods and gas springs. But I will wait for motors first. And do some tests before start building the frame.

    @Rens 10 awg??? I am not planning on using more than 14 awg (2.5mm). My electric installation is 230v/16amp. 10awg is just overkill. I will go with 2.5mm2.

    Why gas springs? What are you planning?

    Mmmm ok, they recommended me to fit at least 10 awg, in my opinion it was overkill too since of the ratings of driver. But again I am no expert. I can fit 12 awg with custom sockets/terminal blocks I have laying around. Right now all wiring are 10 awg. With 8 awg directly from PSU. I create 6dof and the 6 motors will carry the full weight of driver and chair, pedals wheel etc. Gas springs are to obsorb strain on motors amd help with any "stuttering" to smooth things out.

    Ok....motors arrived today.
    Tomorrow I'll receive the power supplies, hall sensors and shunt protectors.
    All set to start welding this weekend. Let's see how it goes.

    @Mike Melga checking in if you made some progress (since you got the motors for some time now). I am still waiting on mine :(

    @Rens

    Hi.
    Well...I'm having trouble where I didn't expect trouble: finding the mechanical parts.
    I already have all electronics: motors, drivers, shunt protectors, power supplies, hall sensors and arduinos.
    I got the metal profiles to start cutting and welding and the hall sensors and shaft couplings.
    However...I'm still missing the rods, something for the pivot on the front and the u-joint.
    Been struggling to find these so progress is zero.
    Also I need something to lock in the shaft to attach the lever. Still haven't find anything suitable.

    Any ideas?

    Just buy a threadend like something like this:
    https://www.toolstation.nl/draadein...QUmmJbupEas7sXHGrg1AVu59ioJhYpbgaAgA2EALw_wcB

    And then female ball joint something like:
    https://www.grandado.com/products/s...DZA6_NBtCCqp-VRzzi4w12lKUrRFoH_oaAogjEALw_wcB

    And for levers something like this.

    Here video of how it works, of course mounted reversed. Watch at 38 sec.


    https://shaft-collars-couplings.sta...--search-/accu-flange--shaft-mounting-collars

    At least this is what I am planning.
    I am currently in contact with a company that is specialized in gas springs/dampers. Which should help the motors with the load and also with smoothening out motion(s). But I can't give any detailed info on this yet.

    Forgot to say, you can then simply mount the lever to it like so:

    For u-joint just go to nearby auto garage ask them if they can help you with that (pretty sure they will). Unless you want a less bulky joint you have to google it I guess.

    Here are some pics of the motor and shaft.
    I guess the rods are quite simple to find. I just haven't look enough.
    I will try the u-joint next week. I am looking for something compact.

    My main problem is the shaft collar and lever. I am trying to find a dealer here in Europe.
    If you find one...let me know :)

    Nice, looking good. What is the diameter of the shaft? I believe it is 14mm? According to the datazheet but I find this to be a strange diameter. (9/16 of an inch).

    I was here wondering....which of these rod types should work best?

    Both can work and sometimes it comes down to design decisions as to which to use. I

    believe a sealed tie rod style may have greater longevity, though personally I used eye style spherical rod ends on my compact rig.
