OK a little time today to fuck around with this. When I take the sensor, (the connector with the resistor) out of the playfield it works fine if I hold it in my hand and test it in switch test. This is with my original eddy PCB's AND with the smart eddy's I bought from tangle. With the original Eddy PCB, it doesn't matter how sensitive I adjust the pot, it won't work with the sensor installed in the playfield, only by holding the sensor in my hand and passing a ball over it manually. Now the thought of trying to dig the notch in the playfield deeper makes me very nervous, if I break through I just ruined a playfield that's 100% finished. So I'm hoping someone out there who installed a mirco playfield had the same problem, and that maybe there's a cure, like changing the resistor to make it more sensitive. Anyone?
