In the thread on puzzle pieces, Rodne mentioned using nitrogen in his AirAssist, which allegedly cuts down on charring while cutting thick paper or mat board.
Has anyone else done this, and to what result? (If you have with/without pictures to post, that would be wonderful).
How would you do this with an Epilog Legend, and what are some sources for adding nitrogen into the air assist? (Is it all N, or a mix added from a secondary line?)
Thanks for any info!
