On some of the first Gen 2 Elite machines we did not include a cover over the Z axis sensor.  
After shipping several batches, feedback was recived that UV/Sunlight was disrupting the sensor causing false motor and homing alarms.  
We’ve been shipping the Gen 2 for a while now with a Z axis cover.  
We are providing the .stl to this cover for those who’s machine does not have the cover.
