Hi, I have a T300 that will no longer calibrate. It spins clockwise very hard into the stop, tries again and then gets stuck in an endless loop. I have now rerun the calibration software about ten times, each time it fixes the problem and I can get a few more hours play. So far I have checked the hall sensor mount, and also tried gaming using industrial strength cooling. The sensor mount is not damaged (save a hairline crack in the mount that I think is negligible) and the cooling doesn't seem to stop it losing calibration. My questions - should anyone know the answers please, I'd be very grateful: 1. What is actually going on - is it the magnet moving on the axle that causes the need for a recalibration? Are there any other possibilities? I've yet to find any guides on disassembly of the motor although I am familiar with doing such things with user-serviceable RC motors. 2. Most people who have these issues seem to report a loss of FFB and having to replace their wheels. I seem to have no such issues, the wheel generally works fine for a few hours until the next time it fails to calibrate - other than this minor hassle the problem doesn't seem to be getting any worse. My question is will it just totally fail to recalibrate at some point? Thanks in advance.
