I have a Gen 2 Elite. Everything worked great during my learning phase. Then I caught router wire between y axis and sensor. After a couple of homing cycles now when I home it it comes back an error that says Y1 axis failed to back off sensor when homing. The Y1 is tight against the senor the Y2 has backed off. The closed loop resets and it operates but I can’t see anything wrong. I cleaned the sensor. Any suggestions?

They sensors are sensitive to light so if you are in an area with sunlight it can throw the sensor off. I have not had the issue but I know others have.
