Glowforge settings for 3mm Baltic birch — tested 50+ times, here are my results

I've been testing Baltic birch from 3 different suppliers and the settings vary wildly. Here is what I found: Baltic Birch from Woodcraft: Full power, 168 speed, 1 pass = clean cut. Baltic Birch from Amazon: Full power, 140 speed, 1 pass sometimes works, 2 passes safer. MDF from Home Depot: 168 speed, full power, 1 pass but watch for fire.
