Not sure if it’s an issue, but I noticed that it says the laser is busy, after clicking on start after running the first file. Then if I click on start again, it connects and the laser performs well. I am burning DXF files for 3D puzzles, using plexiglass 1/16” thick. Is this due to the temporary connection instead of always connected?
