I have seen a lot of information about DD’s QR loosening, which is also the main reason why I completely give up thinking about it.~~
Is the new analog axis wireless V2 system based on software or hardware?
Did they develop new filter software to solve the problem of abnormal noise?
Both. Support is already added in Simucube 2 firmware 2021.11 and later. Wireless wheels will utilize a new module, see https://granitedevices.com/wiki/Simucube_Wireless_Wheel_2
Simucube 2 devices have some noise, that is completely normal. Some tuning changes are coming up in next release, and we will strive for constant improvement, but it is likely that the device cannot be made completely silent without significantly reducing the sharpness of the FFB quality.
