Basic not cutting through 1/4 maple plywood all the way all of a sudden and flare ups!

Hello! I have been running my basic with much success until just recently. I am cutting the same project multiple times on the same 1/4 maple plywood from the same box and same manufacturer. All of a sudden it is not cutting all the way through. I have cleaned the lens and everything multiple times. The only other weird thing I am noticing is a lot of flare up when cutting which I have not experienced. What could be happening all of a sudden??![IMG_7687|375x500](upload://iB


Could be the air assist fan needs a cleaning. My was doing the same recently. After cleaning it, it worked much better.
Here’s a link on how to do it.
