@Drakoz I'm afraid it was a hardware fault. I did exactly as you said and the joystick started behaving erratically, it would spasmodically force feedback and throw the stick around but oddly this occurred the moment I uncovered the optical sensor (nothing happened when I covered it) and then would stop in less than a second when uncovered. Moving the hats however had no effect sensor uncovered or covered. Furthermore after this test, the auto-centering feature died. I appears there was a fault in the optical sensor of what kind I have no idea. I paid premium price for what should have been an almost brand new joystick, the whole thing was unacceptable so I have returned it to the seller. Thank you all for helping especially fred41 and Drakoz. I hope the information above will be useful to someone diagnosing these joysticks.

fred41 your diagnosis is absolutely correct, uncovering and covering the sensor as you have described has no effect whatsoever. Can you comment on the notchy y axis (particularly pulling back) or is that to be expected?

Thank you for the very fast reply. The unit looks very clean, almost brand new, so I don't think cleaning the optical sensor will work, not sure how I would get a brush in there? I've taken photos to show you. Can you comment on the notchy y axis pulling back and also why if I only get the auto centering effect that I cannot adjust even that in the profiler?

Forcefeedback not working. Hello everyone, I hope I'm not hijacking this thread. @fred41 It was suggested to me that I write to you here and to everyone on this thread from the HOTAS/HOSAS/SIMPIT group on discord. I recently bought a Logitech G940 system 2nd hand (I've never owned one before), it appears to be almost brand new (except for the fact the whole box and system smells strongly of 2nd hand cigarette smoke, it was obviously badly stored). There are two things with the system I noticed immediately when I plugged the power in, force feedback is not working in any circumstances (the stick does centre though when plugged in) and pulling back the stick on the y axis is quite notchy compared to pushing it forward (the left/right x axis feels very nice and smooth though) (this when plugged in, joystick is loose and very smooth when unpowered). I have tried the joystick on 3 different systems (Windows 7 Ultimate, 7 Pro and Windows XP home) with fresh IL-2 and ROF installs. I've installed and uninstalled several times the Logitech Gaming Software v5.10.127 (and earlier versions to no avail). I've updated the firmware to v1.42, then I found fred41's excellent firmware fix here and updated that. This had the overall effect on the joystick by making both the axes smoother on the joystick the y axis pulling back is a lot less crunchy and notchy (but crunch still can be felt). Also the static when the joystick is left centred disappeared after applying fred41's firmware fix, but still forcefeedback is not working. Please believe me when I say I have all the force feedback options and settings in Windows control panel, Logitech Gaming software and the games correctly set. I do have some self centering when plugged in and other than ffb the stick works when I tested it in Il-2 and ROF. Adjusting self centering forces and force feedback in the Logitech Gaming software or windows game control panel has no effect at all on the joystick and of course no force feedback I was told if I fire the trigger and press buttons on the stick in the Logitech gaming software I should get ffb effects, while the software registers the buttons I press, the forcefeedback is not functioning at all. I have tried the FS Force Support forcefeedback ForceTest.exe http://www.fs-force.com/support.php (as well as some other Force feed back software), ForceTest detects the joystick and the FF but when it comes to actually creating force feedback effects nothing happens (except for a barely noticeable twitch when I exit the program). I have tested the stick on it's own and with the whole system, I updated the firmware with the entire system plugged in. It's odd that the unit self-centres when powered up but the forcefeedback is dead (and the slightly crunchier y axis pulling back has me worried too). I have the original charger and the kit looks almost brand new so I can't imagine it's a power supply issue. To conclude I'm trying to ascertain whether this is a software issue that is fixeable, or there is a fault within the joystick. I paid a premium price for it so if it is a problem requiring physical fixing I won't be repairing it, I'll send it back.
