Problem with Xtool with watt laser

[Edward (Edward Ricci)]

I am Having a problem with Lightburn connected to a XTool S1 40 Watt. The problem is that it will cut a triangle where it should be cutting a rectangle. Problem is intermittent. Xtool support was very nice but said if it worked with Studio with no problem then it is a lightburn problem. Have Lightburn version 2.0.05. Computer is Desktop Windows 11
