    Ok my shop list:

    - Power supply HP ATSN-7000956-Y000 700W 411077-001 412211-001 do

    - some used wiper motors (i don't know if all available are compatible)

    - two BTS7960-Modules

    - Arduino uno

    - two pots

    I will try complete my parts and do something like this :https://www.xsimulator.net/community/threads/diy-2dof-simulator.4793/
    Or this : https://www.xsimulator.net/community/threads/my-2dof-motion-add-on-for-playseat-evolution.13918/
    So wish me luck :)
    And this is it for now

    I found good things to read so I start learning

    Wiper motors are not particularly powerful, so you want to have plenty of inherent design leverage, so a shoulder of foot mount would be best. Wiper motors are not really suited to a compact design, as that requires lots of torque.

    Have a play with SimCal, that will give you some idea as to the tradeoff between design and physics: https://www.xsimulator.net/communit...e-linear-speed-and-forces-of-your-design.270/

    ok i done some calc and i see whenn i put motors to the front my Pitch efficiency fall to the 9%. i dont want to have big forces but this looks like i must change my idea and put motors to the back

    I am guessing your wiper motors may have a number of wires for high and low speed, is that correct?

    If so high speed is what you are interested in.

    Connect the motor up to a battery, it should be pretty obvious which is high and low speed via its RPM.

    Now I will try to make pot connection the motor but on the other side. I must make hole like m6 maybe and pin to connect with pot.
    I wonder if anyone make it like me. Maybe someone make pot holder do wiper motor on 3d printer?

    I am not sure I understand what you mean, could you please explain a bit more.

    If the wiper motor is ground isolated the case is not live when in operation, which you can check with a test light.

    If you mean the ground wire for the pot then that goes to the Arduino, if that is what you are using. In which case it would be helpful to know what motor driver you are going to use, so we can advise on the correct wiring.
