Not strictly Simucube related but was hoping the knowledge here could help clarify and narrow down the issue.
I have a Simucube 1 with Small Mige (BISS C encoder) and a Q1R quick release. The last week or so the button box on my rim has been temporarily disconnecting if the wheel is turned very quickly left or right. While investigating I noticed that the button box disconnects completely when I remove the wheel by separating the quick release. I assume therefore that the ground connection in the usb cable to the box has become damaged somewhere, so it is now grounding via the motor.
I assumed the disconnecting when turning quickly was due to some minor play in the qr so I ran a grounding wire directly from the button box to the base side of the qr. However it still disconnects when turning quickly.
Is there a something with how the Mige or encoder works that would explain why the ground signal would momentarily cut out when the shaft is rotated quickly?
I just want to ensure that it is a grounding issue with the cable and not something else at play etc.
