    Hello everybody!

    This is my first post in this community and I am glad to show you my 2DOF project!

    I have to finish putting some fans to the motors and a new case to support the wheel and avoid the middle stick. For now, I will show you the images of the process and my 2DOF almost finished!!

    Yuhuuuu!!

    I have played in Live for Speed with the demo of simtools and it's very fun!!!

    If you want some details of my building you can post a question!

    Bye guys!!

    Thanks for sharing your rig.

    What PSU(s) and motor driver are you using and what code is running on the Arduino?

    Here you have! My first test with LFS and simtools in Demo mode:



    I requested a full edition of simtools to test with other games. When I have it I will post more videos!

    Thank you for your congratulations!:rolleyes:

    Hi!

    I used the SMC3 Arduino 3DOF Motor Driver shared in this community. I follow the guide of RufusDufus, and I enter the mode 2 using the SCM3.ino code for Arduino since I use IBT-2 H-bridges to control the motors. The PSU(s) are two different PSUs connected in series this way:

    seriesPS.gif

    One of them is a PSU from a PC with 250W (I think) and 15-16 A, and the other is an HP PSU with 200W aprox. and 15A aprox too. I don't remember now exactly the W and A of PSUs but I am sure that they are different. If you need more details I can tell you all the characteristics of the PSUs when I arrive at home. Bye!

    I have to say that the movement are soft because I set 50% of amount of axis in simtools. However the sensations in the rig are very impressive. I have to adjust to 70-80% of amount of axis and test if the motors can withstand the effort. At 50% the motors are hot but not too much. My problem with the temperature of motors is when I stop to play and I stop the simtools software. In that moment, the motors are hotter (Very very hot) compared when they are running with me on the rig. Anyone knows what are happening? I don't understand. My solution right now is to switch off the motors after stop the software to avoid overheating. But other solution would be better if I knew the real problem (configuration in Arduino? bad configuration in simtools software?) Thank you for your help!!

    A question, Ratafia...
    Why did you decide put the engines in front instead of behind?
    Is it for some reason?

    Thank you!

    motors have to be at a "good" length from the center of rotation.
    they can be front or back :
    by putting the motors in the front, the rig is more compact
