What laser power do I need for 1/4" Baltic birch?
I have a 40W CO2 laser and it takes 3 passes at full power. Am I doing something wrong or do I need to upgrade?

40W CO2 should handle 6mm Baltic birch in 1-2 passes at 15mm/s. Make sure your lens is clean and beam is focused. Also check if your PSU is actually 40W — many Chinese machines are optimistic.

What speed and power % are you running? I cut 6mm ply on my 50W in a single pass at 12mm/s, 90% power. Air assist matters a lot too.
