    Good morning guys... I solved the problem, the iBT2 board was faulty. I repeated the procedure you suggested and in the end everything worked as expected.

    This 2dof model of mine is not finished yet.

    At the front I would like to place the 29 or 32 inch ultrawide screen and control devices.

    Do I necessarily have to sign up for a "do it yourself" subscription to connect to a game?

    The fully functional plugin for Live For Speed is specifically for testing purposes with the unlicensed version of SimTools.

    The licensed version of SimTools v3 has the new integrated repository system for plugins.

    Nice progress. Looks like you have very good range of motion too with your layout.

    You can mount a screen but be warned, the motion system is going to be very hard on it. I fully understand your desire to mount the screen for better immersion.

    When using SMC3 and first powering on your rig, you'll notice it jumps to the center position quite rapidly.

    Now imaging that type of g-shock going on for extended periods over and over and over.

    Flying sim motion is smoother overall motion due the nature of the physics. Driving and even the roller coaster games on the other hand involve rapid changes in direction inducing a surprising amount shock.

    You can dial the in intensity of the motion through Simtools. This would allow for less violent movements but also dials down the "motion sim experience".

    I was actually a little shocked at how intense the motion can be, and my rig is quite heavy compared to your layout.

    If you do mount, AoC makes some pretty good 34" VA panels in the $200 range.

    I think im seeing design issues it that 2DOF?! Your motor arms need to be horizontal not vertical in this situation.. They need to be 45 degrees of the extension arms that lead to the frame.. In other words, Parallel with that upper frame..

    The way you have it set up, it will push and pull the rig forward And backward more than it would down and up... This wont work well with a u joint where it is.. This would slso mean that your post in the back needs to shorten to the height of forty five degree arms.

    The hight removed would be the distance from the the center of the bolt hole on the Arm to the Center of the Crank Shaft.

    Unless im seeing things wrong?! ;)

    Good evening... I ran several tests before assembling everything with the screen and flight/driving devices.
    I noticed that the motor doesn't stay at zero when I turn off the power.
    Is this happening to you too?

    When a motor can't hold the rig mass when unpowered the motors are being 'back driven'.

    Depending on design that may also take pots outside their range when unpowered.

    There are low tech resolutions, where the likes of @Nick Moxley use a pivoting chock, that can be swung into place to hold the rig when not powered: https://www.xsimulator.net/community/threads/2dof-static-seat-when-not-in-use.5996/#post-64074

    And at the other end of the innovative scale @Jon Amico's high tech actuator chocks: https://www.xsimulator.net/community/faq/actuator-chocking-of-back-driven-rigs.417/

    If a sim rig is properly balanced the nose should droop when power to the motors is off.

    Yes, mine nose droops with power off. I've got lever arms that will interfere with the frame itself before it can hit the potentiometer.

    Wow...fantastic, but yours is a pro-level simulator. Today, I finally tested it with the FLS game and everything works properly...fantastic...I'm very happy.
    I don't understand one thing. To make everything work, do I have to buy the "do-it-yourself" license and also the game plugins?

    You will have to purchase a version of Simtools.

    It's well worth it.
