I decided to get Expanded Metal Sheet from HomeDepot while I wait for the honeycomb bed.

Box on left is cut by a $12,000 Epilog Mini, one on the right is by my $370 K40. I ran the engrave at 300mm/sec @ 5mA, vector cut at 5mm/sec @5mA (one pass).
The Epilog is definitely better, but I'm hopeful that with time I will be able to get closer to the Epilog's result with the K40.
