Hi. I am new to Lightburn and am using it with a new laser machine - G-Weike Cloud RF. When I score a circle I am getting a burn mark (sometimes just a dot and sometimes a longer mark. I enclose a photo showing the burn mark at the top of this circle. I used a speed of 300mm/s and power 10% and the material is 3mm birch ply. The laser is a 38w RF. I have previously used a Glowforge and I did not get this issue. I would be grateful for any advice on how to eradicate this. Thank you.
