I also would love to mod a fix for the uneven keys and completely agree with your assessment, but isn’t the position of the orange bar fixed by the angle of the end-on appearance of the long rod, which doesn’t seem incrementally adjustable by force or pressure such that you could “turn“ the orange bar (I.e., the whole rod) and make the orange bar vertical? It seems fixed by the gear position and i am not able to move the gearing on the motor. Any ideas welcome!
