the falcon2 22w comes with a focusing block that has three settings
all three talk about basswood should i use different settings for other things like 3mm acrylic or luan

I have just used the smallest step on the block for 3mm Acrylic

I'm not familiar with the Falcon focus, but on my machine, I have one focus height for surface engraving wood and another for surface engraving stale and metal. For cutting, my focus depends on material and thickness.

My focus block was wrong. Google laser ramp test and see how yours looks. You may want to make a new block.
