Yes, I understood what you were saying, and anyway I did swab the axes sensor while I had the stick open. I believe the axes sensor is clean, as the signal is clean and smooth when I move the stick without blocking the grip sensor, or when I disconnect FFB power entirely. However, when I turn on ffb and block the grip sensor, the axes suddenly have some "noise" or jitter even while holding the stick steady at center. The noise only happens when FFB is on.osterac wrote:When I say the axes use optical sensors I don't mean the one in the handle that senses whether you are gripping the stick. Inside the joystick there is a camera that determines what position the stick and the throttle are in. This video illustrates it quite well:r8dhex wrote:By jittering, I don't mean the shaking from FFB. Even when completely centered, holding the stick steady, no forces. There seems to be noise on all the axes, including throttle and twist, when I cover the photosensor. Take my fingers off the photosensor, and everything quiets down. This happens even on the trunk version I compiled.
Maybe cleaning the lens on that camera or cleaning the tracker LEDs might help?
I might do a video of this to show what is happening.
