When I set up my printer (Batch 002), I noticed that the left and right LED RGB colors didn't match. I used the red 255, green 255, blue 255 command line prompts to try different combinations. I discovered that the left light was fine, and the green channel on the right was fine, but the red and blue were reversed. To fix it, I just changed the order of the wires in the connector to Orange, Blue, Yellow, Green. Now it works fine. Not sure if I had a random bad wire, or if everyone else sees the same problem. In any case, it's an easy fix.
