I am getting the famed Clear Board Sensor. After talking to a person at Carvewright, I replaced the sensor, I get a sensor reading of 151. While looking through the menu at other things I noticed Edge Detection Error E03 - 0400. I have tried putting a better light above it as some people suggest (the reading of 151 suggests that this is not the problem). The firmware at this time 1.182.09788 seconday revision 7. Any suggestions would be appreciated, Thanks.
