Cutting with Neje Master 2S plus A40640

Been trying to cut plywood 6mm as test but can not get any cut. I have been using Neje software .Lightburn and lazerGRBL. I am not using air assistans.
Can anyone give a hint, settings etc…

There are many factors that affect the cutting effect, including material properties, material density, focusing accuracy, cutting speed, cutting power, and air-assisted accuracy and air pressure strength; cutting MDF density boards needs to meet 3 conditions, and air-assisted (0.8mpa- 1.5mpa), the focus is accurate, the speed can not be too slow, the speed will burn the edge.

Tks. Watching some video on Middle Room Workshop and trying to get to know the different software.
In progress!
