I picked up some .06mm thick adhesive backed copper sheets that might be thin enough to cut and I’m wondering if anyone has any tips on settings to start with on the Falcon2 22w?
It might heat up that adhesive so much that copper melts, but it probably won’t look nice. Brass and copper are among the materials that have the worst effect from a 455nm diode laser module. To cut it reliably it would need a fiber laser.
