If your encoder wheel looks like hell, that may be your trouble. Rail driven encoders can't hardly tolerate even a slight amount of wobble from the bearing. They'll wobble one way going up, and the opposite going down. Careful though, some aftermarket wheel suppliers have poor quality control when it comes to the machined bearing race. If the bearing drops out, or simply drops in freely (on a new wheel), it's trouble. If you can rock the wheel even a little, ditch it as this will allow the encoder signal to get an wacky output to the MCU card or whatever the thing is called and goof with the floor encoding.
