    Done with the redesign electronics are next.

    Its only half the size now D23696C3-ED4E-4F4A-A1EB-AACE2F0202FC.jpeg B98540D7-1FBE-4CD1-B5AA-CBAC2560998E.jpeg 9BDEF6B1-8807-47C0-BEBF-9E1737432024.jpeg F0E1EBB4-4A6C-4F65-9718-8A8D82C63BD6.jpeg

    Wiring is also finished

    It is working with limitation so it only tensions with braking and loose to 0% but doesnt loose with acceleration.

    But There is a problem i want to loose the springs but i cant find to limitate the rotation is it posible because when i limitate axis rotation degree it doesnt make a big difference and then when i drop the springs it wil tension to much 9966F29A-F5E0-464C-BD4C-6BAFF713595C.jpeg F6D9A407-1625-43E3-9345-28B812C21FCE.jpeg 2ACBB863-6854-442D-8B20-5BC7365BF32F.jpeg

    And Made a Nice layout for my new to make buttonbox

    going to try to print it in a clean vinyl and make the gray Clear so i can wrap it in Carbon fiber and then the clear vinyl with the layout. 200D0129-C05E-49F4-9E2F-23C5927F12AF.png

    I am not sure I fully understand, but would suggest the range and behavior of the motors can be set in SMC3, and in the SimTools Tuning Center you can set 0 so movement is only one way, but perhaps I am missing something in what you are hoping to achieve?

    Simtools tuning center i set to 0 on one way and that is working fine.

    but i want to limit the degrees of rotation say that for now 0% to 100% uses 360 degrees i want it to use 90degrees Wich i need to adjust to
    Limit it.

    also i have al lof of sound from te motor when Its nog moving when i set deadzone to 12 it wil reduce the
    Sound a bit where can i seak for this problem.

    SimTools will use the available range available as 100%, but that does not mean that is 360 degrees rotation, SimTools also has Axis Limiting to further restrict whatever it has available as a range.

    Mine is working but wondering is any filter or setting to improve brake force i feel like surge is working like suspension travel but when car is stiff. Braking force from surge axis is not so suggestive. Depending on the game. In assetto when I take Quatro s1 working awesome but when play gt3 is not so strong on higher gears

    Mine is working also but i need a lot of deadzone of else Its making weird noises i hoped with the redesign it would be beter.

    i was thinking for a Seatbelt tensioner maybe Its a good idee to use the readings from the loadcell of the brake pedal (of u got a loadcell brake) then Its possible to get constant readings for braking it was just an idea

    When you are satisfied with the generic motion profile you created then you can refine it even further by creating specific car/track profiles in the Profile Editor, located in the SimTools Game Manager. Copy the Default Profile in Profile Editor under the Editor tab, name the copy by the Car/Track then use the sliders in the Editor to further tweak the settings to suit a particular car\track.

    Hi I have question with smc3 my belt start to turn off randomly. I don't know if problem is only rbr or all games. I use v3 simtools. I just dealt with the green line in smc3 and what does the yellow line do. Is she supposed to be within max limit and clip input?. In smc3 works fine but on rbr shit off randomly. When I unplug and plug USB cable it working again. I must check other games also

    Try a proper smc3 tuning first. It's very important. And in simtools i recommend to try heavie like 20 % also. Very cool effect
