That could very well be that more power and faster cuts would minimize the under cutting. Besides setting the power level in watts there is also a parameter on these lasers for pulses per second. The more pulses the hotter the cut, when I got the power level and speed set I reduced the pluses per as low as it will go on my machine (300). That helped reduce the under cut but it was still unacceptable imo.
I may play some more when I get a chance, I still have some foam board setting around.
Hmmm, thanks for doing that test. The laser guy I had cut some foam board for me had this huge industrial machine and it also had some under cutting but it was totally livable. I winder if a higher powered laser does a better job. Man cuts that depron SO fast though. I wonder if the foam boad on both sides make the laser light defract and cause the under cutting.
