I have been using lightburn with my Azter laser for awhile all of a sudden is changed my speed from 380 to 15 at 100% power but will not cut. i tried to change the speed back to 380 but it will not cut my 1/8 wood it just engraves it. I have tried reloading it but it still won’t cut. Help Craft show season is here and I need my laser.

The ratio 380/15 is 25.33, which suggests LightBurn has switched from millimeter/min to inch/min.

Check the distance and speed units to be sure they’re what you expect:
