    Hi all first post here. I’ve almost finished my 6dof modeled off @peacemaker’s design. I can’t quite figure out how to stop my actuators from reacting to the motors. Any ideas? I’ve attached a small vid to demonstrate.

    I am not sure what you are trying to convey, can you please explain in more detail.

    Sure, you can see the actuators “twist” when the motors activate

    Do you have ball joints on both ends? I think using U-joints at least on one end would fix the twisting.
