My Lazer is not cutting completely through material. Some places it cuts completely through others it just cuts 1/2 way
It is possible that the laser tube is losing some of its power if your machine is seven years old. It is also possible that the material you are using is the problem. Other suggestions are that your optics may need to be cleaned or your settings need to be adjusted.
In order for us to be helpful, we need additional information. Are the poor cuts in a particular area of the bed? Does this happen with every material? Did this problem begin suddenly?
