Laser etching fine, but not cutting?

Hi everyone,

I bought this laser
https://m.banggood.com/450nm-5W-Laser-Engraving-Module-Blue-Light-With-TTL-Modulation-p-1337358.html

And I ran through the wifi cutout tutorial and seemed to work okay and I matched the settings in the tutorial video. What didn’t work was cutting out the piece from the plywood.

I’m using 1/4 inch BB plywood and I tried 20% to 80% power on the laser going 50 mm/s with 10 and 20 passes and it barely leaves a scratch.

Any ideas? I tried exporting the gcode and ran it through ugs , I also ran it again directly through lightburn.

I dialed in the laser so it leaves a very fine point and it’s about 2 inches above the plywood.

Any ideas?

Thanks!

Justin
