So I have put together most of the electronics. I was working on the encoders first. I can wire + - A (Signal) into the +X endstop and the B into the -X signal. I have started the code but can't seem to get a good signal from the encoder.

I was using J.Carter(of Earth) from Arduino Rotary Encoders but it was never showing a change in direction. When I changed the code to just print A or B I get a bunch of A and every once in a great while a B. It does the same for both encoders. I don't know if I have a bad encoder or not wired correctly. Anyone have any ideas?
