I keep getting clean broad sensor error. I cleaned the sensor same error.

Did sensor test 10" wide broad readings are across broad 155 to 134 as I go off broad reading is 0.

tried it with a 4" broad that I use most of the time and I get the same error

Can someone help me with this before I call support.

I have a B model machine that has been updated with a Carve Tight Spindle.
