I’m brand new here - cut two projects, first one beginning the gift of measure. fired it up today and the laser isn’t firing AT ALL. Nothing is happening in the tube. I saw a recent posting where the person asked if the power defaulted to 1. I checked mine and it is at 1. Question is if this is my problem and I’m using proofgrade material, how do I go back to the automatic settings? If I can’t go to automatic settings, what is the power supposed to be on each cut, score, engrave?
