Don't know if there is a way to tell the encoder or controller to "reset" the alignment setting. I just posted some pictures in the repair thread if anyone else wants to see.

Here is the encoder and wheel. Doesn't seem that delicate as the other ones posted:

It’s likely the position and it’s likely electronically calibrated from the factory. I would make a mark on each end tighten it down and retest. Then move it slightly and retest again and continue to do so until you find the sweet spot. It doesn’t look like there is much room for adjustment so if that is the issue, it shouldn’t take much to find the position as long as you have a reference point as to where you start making adjustments from. It looks like there should be sensor on the board that would need to align with the black outer ring on the round wheel on the end of the shaft.
