Quoted from Yakrobat:Nothing is plugged into J207 or J209, might this be the issue?[quoted image]
Nope. They are clones of J206 and J208 directly above them and are interchangeable. What were the results of testing J206/7 J208/9 as suggested by buffaloatx in post #8 above?
Does the rapid switch registering happen with the connector on the trough receiver board (board with black LEDs) disconnected?
