I wanted to try cermark so I changed my settings to the recommended setting for my 60W which was 90% pwr 20% spd and 600 dpi( which is .0423 scan gap on my laser.
When I ran it all it did was go to the start point and run a straight line up, laser not firing. I tried several different ways to run the file no joy. then tried to run a previous used file at these setting same result.
Link to youtube video showing what happens. any ideas
