I’ve never heard this weird clicking noise before it’s making when the laser is hitting this board..? I have cleaned the nozzle after I heard it and I can’t tell that anything is wrong this is my third set of 2 and it hasn’t happened on the other two sets but these two boards in the video are the first set of that type of wood. Anybody know what’s up? I really need to get these done tonight. :(  https://vimeo.com/1029921253
