Laser: 65 watt Laser Pro Explorer
Material: 1/4" Extruded Acrylic
Problem: When cutting acrylic I am getting "flash back" from the aluminum honeycomb vector grid which is scarring the acrylic. I have tried cutting with paper backing on both sides - get paper burn with recommended settings and any variation of said settings that will cut through. I have tried cutting with Sticky Mickey mask, which is better, but still having problems. Best results, with least flash back, at 1.3% speed, 100% power, 1000 PPI, but still unpredictable flash back.
Any suggestions, recommendations would be most appreciated. Thanks!!
I will be unable to respond to your posts tonight, but will get back with you tomorrow, so please don't feel I am ignoring your good advice.
