    Where exactly? (sorry not sure)
    Tried it with two games, with both it does the same thing, only with rfactor there is no movement at all.
    With AC there is movement but a total chaos.. :)
    These are my setting also captured the min/max values from the game running a mid car in monza/silverstone

    @Greg83 if it is your assetto corsa profile (game engine) what i am seeing its wrong and that's why you have that strange motion when you fire up assetto. it should look like rfactor2 profile to be correct

    @insanegr : Changed the setting according to advice and seems better. Settings are now:
    AC settings.jpg

    Made a video for you to see it better. Upon sitting in the car the default position is still tilted, at 07 sec the only reason I come back upright is because I shift my weight over to the right :)

    Has been already said, but you have no output in rFactor because your tuning center settings are high like hell, and you mixed the axis settings of AC, you cannot combine different axis on one axis.

    @insanegr : fiddled around as you suggested and Surge seems to be better.
    But the seat still tilts to the left like in my video, then I shift my weight over and it seems okay, until a turn, then in tilts again. Also gets stuck in the left tilt a lot.
    Wanted to uploade these, maybe you can see where do I mess up:
    Fixed setting which I do not touch:
    fixed.jpg
    Diffrent tries:
    versions.jpg
    Version 4 seem to be the way, but god damn this stupid tilting thing......
    Ohh and it only tilts when AC loads up the car ingame. In the menu/windows when I turn on the seat it is fine in the middle ....

    the very first thing you have to define is that dofs are moving the correct way. to do it you have to do it one at the time and go on to the next one. when you are done with all of them then you can mix them all together but have to do it one at the time to figure out that dofs are moving correct.
    look at dof 4 5 6 perhaps you have a forgotten value and tilts your rig when you power assetto. have you tried another game too see what's going on there?

    Hey guys,

    Well to be honest and to put it in a diplomatic way I don't get why is my rig behaving like an insane cat...
    Tried 3 games yesterday, AC/Dirt Rally/rFactor 2 and all tilt my rig to the left for some reason.
    () its like 90 degrees..
    Tried DOF1/2/3 with only 10% of Surge and tried all 6 axis, but behavior wise the only change was, when choose axis 3/4 or 5/6 no movement at all.
    Done the base setting for Tuning Center as suggested, it was Monza and a Dallarra single seater.
    My interface settings are:
    settings.jpg

    Thanks Guys for the help!

    I don't know what code you are running or how it is calibrated but try completely removing the Startup - Output and Shutdown - Output values in the SimTools Interface Settings.

    start up and shut down input has to be empty.

    yes my startup/shutdown is empty also. but can he also attempt to invert or adjust the numeral that represents the right motor. i know this may sound redundant, but if removing the startup/shutdown commands doesn't work, have you tried adjusting your pot to the rear some?

    Hey Guys,

    Soo first things first!
    Code: SMC3 v 0.63
    Remove the start and end output, settings look like this at the moment:
    base settings.jpg
    When getting to the sway setting in the output testing doesn't it move really rough?
    Later you can see the test with SMC3 Utils with sine. It freezes for a moment, but that is something that never happened before!
    Should I try a diffrent code?
    Bruce adjusting it where exactly?

    @Greg83 i was speaking of adjusting it at the point of the coupler, or twisting/turning the body of the pot to center your right side.

    If you check with WindowsSMC3Utils leave the motor power switched off. Move the seat so that it is in the center position and check the green line on the SMC3Utils chart is in the center (verticle) of the chart. If it isn't then as bruce says above the POT coupling needs adjusting.

    By the way if you use start and end codes then you would need 512 to center the rig as SMC3 is using 10bit numbers. It shouldn't be required though.

    Hey Guys,

    Upon having it in the center in SMC3 utils:
    Center.jpg
    This is the phisical position of the motors:
    IMAG0158.jpg IMAG0159.jpg
    My reference video was from the Crate project's video:


    They seem to be in the correct position?!
