GF3 X axis now very erratic

[Farnley]

Joystick was working ok , but a little sticky

Decided to clean cams (and replace springs) and follow online guide to regrease the dry clutches

all went well until i reassembled , definitely no longer sticky , but X axis is erratic (Y and rotation all ok , all buttons working ok , all lights looking good on BB and joystick) , and despite re taking apart 3x now , and trying re calibration the X axis moves but not as expected , very erratic and does not centre i calibration software , although physically it does

I was very careful regreasing but could a sensor be dirty now?

Check if there's any metal residue stuck on the magnet. Also, you'll have to reset to default, reinitialize and recalibrate after taking it apart.
