My distance measurement unit has stopped working.  When I click on the auto measure, I get this error.

Distance measurement exception.
Please check the distance sensor.
Error code M363 so

I have had my tools S1 40watt for about two months, and I know I have the distance sensor and pin-up in the right place.

I tried everything, including removing the 40-watt laser and cleaning it well.  I just don't know what to do next.  

Please help!
