Thats sound intressting. I have to Test it too

The damping/friction/inertia filters cause current to be driven to the motor to cause the smooth torque effects, so if anything is going on with encoder or motor drive electronics, they would only show when there is some torque being generated.

But, just how non-smooth is it? We havenā€™t had any similar reports recently.

basically, when not ingame, by turning the wheel left/right, even slowly, I can feel something like micro-steps in the rotation, not as generated by the magnets inside the base but as the wheel is powered by belts, if that makes sense. ingame, the buzz effect is felt very clearly when turning the wheel left/right fast as in the last chicane at Barcellona for example.
I was thinking it could be a problem of ā€œdirty currentā€ at my house, given that lately I had some interferences in the tv/hifi audio, so I was looking at something like this if it can be of any help, and off course not being harmful to the Sc2 :

I would like to add, in my case the buzzing feeling is coming under high loads when the wheels of the virtual racing cars are loaded.

As I mentioned beforeā€¦in my case it only occurs after I drive for a weile.

Im curious if the powerplug-think helps.

The power supplies are regulated switching power supplies with rather large output capacitors for filtering, and the power draw from the PSU is digitally controlled by the servo drive, so it is very unlikely and almost impossible that the quality of the mains power would somehow have a measurable effect.

But anything is possible, as we already know that the unimplemented directinput inertia effect (the calculation does not do anything) has a difference in the driving feel according to @SuperMonaco_GP :wink:

Cool, it took another person opinion and more than one year to take care of messy Direct Input filters!!!

I can show you the part of the of the code of the wheel base that calculates the inertia effect.

    switch (ef->type) {
        case UsbEffect::inertia:
            // effect not implemented, do not do anything
            break;
    }

And, I might have mixed up @Alfye20 and @SuperMonaco_GP in this case. I apologize if that is the case.

Pretty sure SuperMonaco_GP meant Constantly Operating Filter Inertia as ā€œTD filterā€, there is no DI Inertia slider in SW as far as I can see.

I just read again Mikaā€™s reply, yes correct @Andrew_WOT

well, I admit I feel dumb right nowā€¦all the vibrations were apparently caused by the slipping of the inner clamp around the main shaft. I installed the simracingbay extension and I guess I didnā€™t tighten the bolts enough so that they lasted for a bit and then they started to give that sense of buzz under load. I took the chance to do a clean up of win10 in the meantime, letā€™s put it this way :slight_smile:
(luckly I didnā€™t purchase the new power strip, and didnā€™t waste anybodyā€™s time making an assistance ticket)

Sounds good buddy. I think I will tighten these screws. Have I done something wrong?

Could you do some testing for me?

Iā€™m curious. Is this working, even when the unit is warm?

In my case, the problem only starts after Iā€™m driving for a while.
