    The engine plates being thick, I shortened the fixings of the electric motors

    Today I did a first blank editing to check that everything works well

    The first tests with a 12v car battery were done empty then with my children (about 40 kg) then with me (80kg).

    Today I fixed the cards in a box and installed the radiators on the Moto Monster card. 20200623_210054.jpg

    For fixing, I used clothespin springs with heat shrink tubing 20200623_185254.jpg 20200622_115313.jpg

    Tomorrow I wire the simulator and I carry out the tests.
    In "Game engine" what are the effects that you can configure?
    With the demo version of simtools I have performed "pitch" and "roll" tests. Can we add other effects on a 2DOF?

    Neat work, do you have a fan as MMs need plenty of cooling.

    Yes I have planned to install the fan on the cover of the case so that it directly cools the Moto Monster card.

    Today I carried out the wiring of the simulator.

    I have an engine which tends to vibrate / jump when I turn on the simulator: the simulator lowers the crank of the engine and this one tries to maintain the horizontal position. Suddenly it is not good, tomorrow I will try to reduce the length of the crank of the motors. In addition the movements of the simulator are really too important so it will reduce them.

    Is it also possible to have a gradual start of the motors?
    I changed the "Dead zone" in the arduino program to limit the shaking but it is still very abrupt

    Just checking, are the motors ground isolated.

    If you mean a motor can't hold under load then it could be that you have limited inherent design leverage. Worst case you could move the motors down near the pedals to get greater leverage.

    I reduced the distance of the cam, I went from 44 to 30 mm of center distance.
    The movements are more limited but I find it much more comfortable.
    It also greatly reduced shaking.
    I would try to move the motors towards the pedals in order to see the changes that this causes.
    Thanks again for the advice :thumbs

    This week I made a new support for the steering wheel. This one is lighter. I will paint it with the rest of the simulator when the tests are finished. 20200704_223320.jpg

    I also
    installed the emergency stop and moved the motors to the front of the simulator.
    There are fewer jerks but the simulator seems to have lost the amplitude of the roll. 20200704_223541.jpg

    This morning I received my simtools license. I also downloaded the Asseto Corsa plugin to do my first test.
    Everything works well.
    Now I need to refine the settings: I find that at the pitch the braking movements are good but for acceleration there is not much amplitude.
    For the roll, it is a little weak in amplitude. Game Engine test 1.JPG
