Hi I realised my Happ Ball was not moving on the X Axis very handily, just stuttered across the screen. After much trouble shooting I think it is the sensor board, the reason I changed the two boards around and now it's the Y axis doing the stuttering, and the X axis is fine. This seems right yeah? cant be wiring as I never changed the 4 pin connectors, I'm asking as I don't want to order a new part and it may be something i have overlooked. Also I'm in the UK and can only source them in the US and shipping isn't cheap if anyone knows where else I could source one. Also the only ones avail are Rev C where I have Rev D, but thinking this will not be an issue. Any help much appreciated
