I have a new brand k40 from monport, there’s a diagonal cut when cutting. It happens with any shape
Note the circle bit.

Is there any advice?

Is your laser head mounted correctly? Is it perpendicular to your work surface?

How thick is your material? It’s likely the focus that it causing it. Try a ramp test and see if you can get better results. https://www.youtube.com/watch?v=KWrS1MsRoIM

Thank you for the advice, I´ll check perpendicularity (as is a brand-new machine I didn’t) The focus was done before the cut with the ramp test procedure.
