Hello, I replaced my lens and mirrors on my 60 watt co2 laser, run the focus test, aligned mirrors and everything. Run the material test on the 1/4" basswood and it cuts thru using speed of 10in/s and power of 55% and 5 passes. Then bring up my design of three boxes and a single line that cuts the wood in half. However, it only cuts about 75% thru the wood. Does not makeany sinse.
Your profile says “Atomstack” and “Ruida”, so more information about the machine you’re using will help.
Take pictures of the beam spots on targets at the mirrors so we can check your alignment. It’s easy to miss something obvious.
Have you run a ramp focus test? What does the spot look like at the best focus level?
Upload the lbrn2 file with your design so everybody can look into the settings.
Help us see what you see, because we’re flying blind right now.
If its cutting through at all in certain places I would also confirm that the wood is not warped.
I have had my fair share of issues with thin woods that have settings I know can cut through but due to being warped they are not in focus. Sometimes entirely and other times in certain portions only.

Target single pass cut values for your speeds/feeds. You are moving way too fast to effectively cut 6mm stock… You have to give the tool time to do it’s job or work.
Multiple passes increase the likelihood of many issues. A cutter does it’s best work with a single pass.
This is my 40W China Blue with 5mm sub flooring from Home Depot.
You should be able to do better than this with at least 50% more power and on basswood… sub flooring is pretty tough, unpredictable and has large variations in the same sheet… but it is very cheap.
As @ednisley advised, post a few photos of the target, especially at m1.
A burnt through hole or a black circle doesn’t tell us anything. The spot should be dark in the center and get lighter as it radiates outward.
Anytime you do or check an alignment checking the TEM mode of the tube can be checked when you verify the spot on m1 is centered.
If the tube is OK, then a recheck with target photos of the various setup points for a proper alignment would be the next logical step.
Good luck
