Alright… I experimented and optimized a decent amount. Someone could pick it up where I left off in the future to optimize for sure, but a decent start. Can someone please add this info to the shared google doc settings spreadsheet? Or I can if you send me link to where it is (forgot)…
BE SURE TO VENT TO A FILTER… LOTS OF SMOKE AND SOME IS UNSAFE TO BREATHE IN. I used an enhanced external fan routing smoke through tubing into the GF filter.
1/8"th EPDM Foam + Adhesive backing:
3 passes, Speed 500, Power 55
Clean cut through foam (with clean edges).
Did not cut through the adhesive backing layer except slightly in corners where laser slowed down.
Slight flash/fire burn on top surface but not bad.
1/16"th EPDM Foam + Adhesive backing:
2 passes, Speed 400, Power 50
Clean cut through foam on straightaways, but burned on slowdown corners.
Did not cut through adhesive backing at all.
Slight flash/fire burn on top surface but not bad.
