Hi hunter. I already did the auto focus. Unfortunately, that is also one of my problem. Before, when cutting 3mm acrylic, I'm using 100% power and 3% speed and it works just fine. And just last week, when I try to cut using same setting, it did not cut through the acrylic sheet.
Going back to leather cutting, I'm using 2D design and corel draw. I've read in another forum that there is an air assist in some laser cutter to help cut out leather, are you aware if it is also available to lasercam?
