The targeting laser stopped working. While the point laser was still kinda operational the cross had just disappeared. It took me a while to bring myself to look into the issue. Turns out the line lasers are covered in soot. The point laser has its lens deeper in the housing to it is a bit better protected. Luckily everything can be wiped away easily with a wet paper towel and/or cotton bud - probably because we mainly cut wood. If you are cutting a lot of acrylic things may look differently.

Anyway. After cleaning the targeting laser was working just fine. People cutting a lot of plastics may want to consider some acrylic covers covers for the lasers that can be cleaned more easily or even be replaced after being fogged up with acrylic vapor. But for now I am content with the laser and will leave it as is.
