Managed to figure it out. In all of my playing around I forgot to change the C parameter back. Now to deal with the tuning as it is sitting there humming
@samlogan87 IMHO, twisted pair only makes sense for differential signal or a single signal twisted with a GND wire.
Twisting A and B channel of an encoder could lead to false readings, right?
IDK the LDO wiring, maybe they did it right?
