When I cut very small parts on the laser at my maker space, the small parts sometimes fall through the honeycomb mesh under the part I am cutting.
I’ve often thought about putting a “sacrificial” piece underneath the piece I’m cutting. Something that will not be cut all the way through, so will stay rigid. It would prevent small pieces from falling through.
Has anyone ever done this? Are there problems with heat dissipation? Are there materials that are preferable to use as the “sacrificial” material?
