    Hi guys,

    just want to confirm that everything is working

    all the computer needed was a reboot after installing simtools !

    the correct syntax as @yobuddy mentioned is TGT<Axis1a>,<Axis2a>,<Axis3a>,<Axis4a>,<Axis5a>,<Axis6a>

    thanks for the help :)

    Here is a video with the F3 tub fitted



    It looks like it has the power to lift the whole car not just the tub !

    heave step test - the sim is moving in small steps

    the tub is carbon fibre approx 35kg, the base is many times heaver

    the base is lifting off the ground

    need to find someone brave enough to get in it LOL

    This is a very nice project Gadget999. The cheapest way to build a 6dof in my opinion.

    Looks quite accurate if you ask me. I like your approach with the controller/software
    and h-bridges.

    The project is on hold for a short period whilst I order a new motor driver

    I tried a new power supply and it gave off a lot of noise - the circuit board interpreted the noisy signal as movement on the encoders - it tried to move the motors to many different random positions very quickly and it looks like a motor was driven in both directions at the same time - the motor driver did not like it !

    I will code a filter so that the encoders can only count so far in one control cycle - if its above a certain threshold the motor will stop with an error code

    next job is to fit a OSW mige ffb steering wheel and hydraulic pedals
