We give this error when one side of the axis is a lot longer than the other side, so to us it appears that it is trying to use a throttle input to map to the steering (that is something that only turns in one direction). 

This can happen in two ways:

  • - You may be only turning the wheel all the way left and back to center, rather than all the way left, then all the way right then back to center. 

  • - You may have forgetting that the wheels turn more than 360 degrees and not actually turning it back to the center of travel. In this case the wheels both turn 900 degrees, that means there are three places where the wheel can point up, but only the middle one is the center. The wheel turns 450 degrees in either direction and points up at 0 and +/- 360 degrees. You need to turn it one more full revolution back to center when calibrating.
