I need some help. I have a new XTool P2S. I set it up on Friday and it was working great. I took the crumb tray out to empty it. when I put it back in it started creating really large dark lines. The top line was supposed to be a cut line and the other three scored. I cleaned the machine thinking maybe that was the problem. I cleaned the mirrors and the lense. Now it acts like it is cutting but no laser beam and not cutting or scoring. What could be wrong.
