I don’t get much time to spend on the laser, but this was a project that allowed me to have an excuse to play. My son’s 4th birthday party was Paw Patrol themed. Normally I’d do this with a few print outs and a razor knife but, lasers are way more fun! I had problems with the import/trace features, so I ended up redrawing the original logo in Inkscape. The material is Wilton Brand Sugar Sheets, used for cake decorating. The colored ones were a joy to work with, the white was a horror story since it randomly reflects the beam. Cut fast and lowest power so the material doesn’t burn. The toasted edges taste like a marshmallow toasted over a campfire, yum in small doses! The sheets are cut and stacked on each other to make the logo (the red is the only one inlayed).
Alignment marks: 1200mm/min, 25% power
Cutting: 1200mm/min, 50% power, 2 passes
Blue and Red :
Alignment marks: 1200mm/min, 30% power
Cutting: 1200mm/min, 50% power, 3 passes
Engraving the dots on the blue: 1000mm/min, 30% power, 0.010” step over
Random stuff happened 500mm/min to 1200mm/min, power from 20% to 100%. Settled on 500mm/min, 40% power, but again in different areas of the sheet these didn’t work.
Done on the 4W unit.
