I did not understand someone can help me please
Fixed my issue. Makes me wonder however if there is any underlying issue with the servos we have or if we caused any damage to them using it while the new firmware while the issue was present
No, there isnât. Not sure what will even give you that idea. These arenât plastic wheels. I have been abusing servos for over 6 years now, never managed to damage 1.
I still have my original small Mige here, which was my alpha test-horse. If I couldnât break that, you wonât break your SC2

Just a thought. Thanks for the reassurance 
Is it possible that this issue people had with the latest firmware was due to an issue with the flashing process? Given that there were apparently no code changes in that area, maybe it would be worth someone that has downgraded to try 2020.3 again to see if it still gives the same issue?

tried it already and still issue persists
No. It will either work after flash, or not. I am quite sure a Mika will have programmed checks/watchdogs in to ensure a flash goes as expected. The only time really a flash can get corrupted is during a power-failure, USB comms interruption, etcâŚ
But I have not yet managed to brick a SC2 controller to the point it did not recover itself, or I couldnât force a recoveryâŚthese things are bullet-proof.
Smooth again, thanks!
I have tried going back to the 2020.1 firmware even though I hadnât noticed a difference going to 2020.3
After going back and forth a few times, there is definitely a subtle change going to 2020.3. As has been said there is a slightly more grainy feel to the wheel. To me it feels a bit like cogging, as if there were gears in the wheel now. I can actually feel it through the rig on my feet too. It resonates through the rig frame so you can feel and hear it. Iâve tried changing all the filters and nothing seems to alter the effect.
I could reproduce two ways; on the desktop with no wheel, rotating shaft by hand (strength at 5%), and in PCars2 stopping the car on track and rotating the wheel left and right by 90deg.
Seems like something low level causing the resonance, rather than a change to the filters.

Yeah, writing program data to flash memory either works, or if it fails then the firmware is not going to be run at all and Simucube would stay in the Firmware Upgrade Mode. Same would also happen if the device would somehow corrupt the firmware by itself.

What you are feeling is the Telemetry Data acquisition, every so often TD reads/wite (dont know) telemetry and forces at the shaft are reset, rendering virtualty impossible to play non FFB games

I have no problems. Not with the trial version and also not with the official firmware

Itâs a shame that many of us are having issues⌠The new version had me excited for some of the new features.
in the end I came back to the Simucube_2_True_Drive_2020.3. once properly set up, itâs really great
