    Hi Everyone ,

    It has been a while since my 2dof project.
    https://www.xsimulator.net/community/threads/2-dof-flight-race-build.16924/

    Last 2 years I didn't do much with my 2dof rig, because of serious back injury.
    While recovering I came up with the idea of a building a new simulator.

    The 2dof build was built with simple tools, so upgrading some tools was my first mission.

    I build a workbench and bought a vice and a drill press.
    Then came the idea of building a cnc milling machine, that took over 6 months to complete.
    But I got it to work and it does cut aluminium.
    Needed to learn basic CAD/CAM, I use Autodesk Fusion, got the basics under control so I can make parts for the new rig.

    Now it's finally time for new simulator ideas.
    A 6 dof stewart platform would be great, but with the cnc taking a large part of the budget.
    I wanna try and make a 3dof with heave first.

    I really like sebastians sim
    https://www.xsimulator.net/community/threads/my-3-dof-with-heave.18449/

    And Codac version of the same approach

    https://www.xsimulator.net/community/threads/f1-like-3dof-simulator-with-heave.18845/

    The 500Watt motor with gearbox they use in their simulator look powerful and budget friendly.
    I ordered 3 of them with the same gearbox of Sebastian and start building the 3dof simulator.


    With the experience of the first build, better tools and the help of this forum,
    I’m looking forward to a new simulator adventure.

    I will post regular updater and lots of questions.

    My Motion Simulator:
    2DOF, DC motor, Arduino
    Started with the design for the simulator base , 120° angles between motors.
    I will use 4040 aluminium profile and standard corner brackets .center and corner plates will be made out of 6mm aluminium.

    I Got started on the simulator base. It got a bit bigger then planned:grin. (1mtr x 1mtr)
    I had some 12040 aluminium left from the cnc machine project , and made use of that.

    Wanted 120 degree angles between the motors.
    So Cut the 60° connectors on the side out of 8mm aluminium with help of the cnc.
    Waiting for more alu. to arrive, to make centerplate and make motor mounts for the other motors
    the mounting plates for the motor are also 8mm thick , hope this will be sturdy enough.
