We have a 30w Laser, and we are trying to cut foam for transport trays. (Cut out hole, put object in hole, it's protected) We are having some issues on the 1"+ sizes. We are cutting medium density open cell foam. It's cutting the foam, but sometimes is needing a second pass. or because the beam's focus is to short it's not concentrated enough to get all the way through.
what ever the cause, the edges are getting melted and the cuts are not looking great. Also we are producing a lot of smoke and staining the foam.
any thoughts or tips on how to improve this would be great!
