How to fix Fiber Laser engraver - Not marking - Ezcad2 - Help

I’ve made a video on an old account that has been getting questions for a longtime. I no longer have access to that account so I’ll post there here and hopefully it finds its way to the people needing help This should help resolve the most common issue new users have with a laser engraver Any other questions, just ask! Will post more videos as the questions come in
