Or, can you repeat the issue if you enable the centering spring and bumbstops in SimuCUBE, and just turning against the bumbstops - no game required.
If there is an encoder issue, then you can just press e-stop and start driving without forces, the encoder does not know if there is torque in the motor or not.

I engaged the E stop and rotated the wheel while watching the simucube overview. There are two specific degrees of rotation where the on screen wheel appears to skip a few degrees.
hmm, interesting. You might want to connect to the drive via Granity, to see if you can spot a discontinuity at those locations when carefully observing the Position Feedback indicator on the Testing tab.
OK. Will have to come back to this tomorrow. Been a long day. Mika, thank you so much for all the help. Iāll let you know how I get on. Hopefully get to the bottom of this.
If it is not happening in other games then it is probably something to do with the gameā¦ Because it is happening at the end of a rotation I am thinking it is the way the Game is handling Software Bumpstopsā¦ It doesnāt look to be happening mid turn but only when it stabilizesā¦ Does it happen with other cars in RF2. It would be weird that the encoder would slip but there could be something going on there as it is at specific degrees, however, if it is the encoder it will also happen with every other game and car at those specific degrees of rotation as well.

The issue was indeed in-game as @bsohn suggested . Turns out that somehow the bloody āsteering helpā was changed to LOW. This was causing all the wheel movement. Really sorry for the false alarm folks. Many, many thanks for the help @Mika @bsohn . Elated and embarrassed at the same time.
Glad to be of help and glad you figured it out.

Please post the whole log - that just a beginning of a normal startup of the SimuCUBE. You can use pastebin.com or something if this forum software does not allow it.
Yeah, sorry for the uncomplete logs, I didnāt notice there was a string limit
https://pastebin.com/JLEWR5tn
That log includes normal simucube startup, then you manually reset wheel center point, then you launch granity and come back from there, then you run the motor configuration wizard as far as I can see.
If you are loosing center point while driving, then your shaft coupler is indeed slipping, or the encoder is slipping or is loosely mounted that allows it to shift a few degrees from time to time.
I donāt understand anything.
Sorryā¦
It was the central screw of the encoder! After tightening everything is fine, yeah!!!
Thanks Mika
Glad you got it fixed!
Howdy,
After a while I turned up my SimuCUBE on and update to latest firmware & software and the wheel feels stiff now to turn after it has phased (Last time I have had the manual centering configured).
I can feel the wheel chattering and even hear some noises from it.
When I put the profile in to safe profile, the wheel does not have the force anymore but when I adjust the overall strength in my current profile, it does not have the same effect.
I have small mige. Any other information I can provide?
Hereās my log after the start up:
https://pastebin.com/Qf6GbEvy
FFB effect creation log:
https://pastebin.com/vJc93L1q
Edited to add that the wheel works in ACC somewhat at least but I am worried about the wheel behavior when not in any driving title.
stiff to turn sounds very, very strange. Have you tried creating a fresh new profile? Is the wheel stiff to turn also in Granity mode?
Tested some things with a new profile and I noticed that it was the Damping, Friction and Inertia setting that made the wheel stiffer.
I had following settings:
Damping 3%
Friction 0.75%
Inertia 6%
Should those values make the wheel a lot heavier than without?
yes, those will make the wheel heavier. There might also be grainyness, if you have low resolution encoder. I guess you have 5000 PPR / 20000 CPR?
Aye, exactly that.
Glad it was only those filters and sorry for making false post. Got a bit worried when wheel suddenly changed. Just have not used those filters before 
Sent you some Discord PMās too but you can now ignore them. Thanks!
