If one or more of your encoders “feels” different when turning compared to the others, that is not a reason for concern and does not mean they are broken. Each encoder has small manufacturing differences which are beyond our control. As long as you can reliably scroll and adjust parameters, that’s all that matters.
Also, it IS possible that the problems you are seeing are due to a corrupt SD card, so I always recommend you first re-flash your card using the image in the forum, and put the latest software on it, and then see if you still have the problem.
If you still have a problem, make a video where you turn the encoders at various speeds when scrolling through menus and ideally also on the P-page of a module (e.g. an LFO), and with only one module in the patcher grid, so we are sure this is not a CPU load issue or an issue related to a specific combination of modules in the grid (i.e. software bug), rather than being a hardware issue.
When turning encoders, use one finger to spin the encoder instead of turning the encoder like you would turn a normal knob, so we can see it’s not due to reverse movement that your hand or fingers make, without you realizing you are doing that.
Lastly keep in mind that as @thetechnobear has mentioned, that there is a “mapping” from encoder data to parameter increment/decrement/acceleration, which is purely in software, and is very subjective and very personal. Everyone has different expectations on how encoders/parameters should behave when turned, which does not mean something is broken.
Hope this helps.
