Hi
I have not started cutting or engraving yet, but if I recall correctly there are two types of acrylic. I know one is cast acrylic and the other is I think called molded acrylic.
They both act differently concerning laser cut/engrave.
You might find your answer if your using the one that’s unsuitable.
Other than that, I would assume once focus is good, it can only be speed or power that needs adjusting.
Hope this helps.
Pete is correct. There are two types of acrylic. Cast and moulded (AKA extruded or injected).
From memory cast is good for Diode laser cutting, while Cast is good for CNC work.
Most people have used the default Luban settings successfully for black acrylic. I am guessing you have moulded acrylic though.
There have been a few posts about using Acrylic in the SM Facebook forums.
Here are the recommened settings:

Hi,
I hope you are right with types of acrylics. I will try to find what kind is this one and try with the another one.
Every square is burned at different speed to find best one but results is as you can see, little s***t

Apparently, the Molded acrylic is the best for lasering & the other is called extruded acrylic…and molded is more expensive.
It has also been said that leaving on the protective film when using colours that are not usually suitable can help and also water based black paint…easy to wash of with no scratches.
Worth experimenting with but also heard many say that switching to Co2 is much easier than diode for acrylic.
When materials, focus etc are all correct its probably a speed or power issue…too slow & too much power is bad.
Just one other random tip that may be of use when using very thin materials…like paper, foil etc.
Place the material under a sheet of glass to keep the material ultra flat and not curling from the heat…the laser goes straight through the glass to cut the material.
