Problem with Thrustmaster TWCS throttle not going always going back to zero

[Youtch]

I recently detected an issue with my Thustmaster TWCS throttle, if I go back to ZERO fast, as soon as it reaches zero it jumps to 25% ish.

The only way it really goes back to real ZERO is by going back slow.

 

I wonder if it is hardware or software since I recently upgraded to windowns 11.

 

I reinstalled driver, try to change USB ports, and seems to keep happening. It is visible in the game and in joy.cpl when checking calibration

 

Not very practical for dogfighting or landing plane.

 

Has this happen to anybody else?

Not sure that these will help:

 

Cleaning

 

Potentiometer replacement info.  Thanks to Sokol1

Thanks for this video.

 

The weird part for me is that it seems to fail only when I jump fast and strong back to zero throttle. On the calibration tool, it indicates zero half a second and then jump to around 25%, as if the mechanical shock was causing the potentiometer to move, regardless of the actual position of the throttle

 

If going slow the potentiometer seems to be working properly.

 

Before going full surgery on the device I might try to map software to lower threshold.

Try not pushing the throttle to its limits when you calibrate it, stop short of its full physical limits at top and bottom. This worked on my old CH throttle. But, that won't help if the spiky thing is the real problem.

Highly subjective/anecdotal, but: From my experience I'd say it's HW... or rather that I doubt that it's your OS. I've used my TWCS on Windows 11 only and it never showed this sort of behavior.

 

If it's an older, well used TWCS we're talking about, my first thought would probably also be the pot. Some pots seem to be able to go forever without going wrong, while others (prolly cheaper ones) will freak out on you rather quickly and will require servicing/replacing. My ancient CH Pro Pedals from the mid 90s have never been opened and still work great while my (~2015) CH Pro Throttle's pot started to spike/jitter after a few months of use.
