Trying to get something legible

Hello people, I’m pretty new on this forum.
Been playing around with settings on lightburn to try and get some legible looking pictures engraved. I have seen how well others peoples work comes out.
Here’s how some of them turned out today.
Using my eleksmaker with a 5.5w diode with a new S16 diode lens fitted today.
1200mm/s 30~45% power, 200 dpi l. still trying to figure stuff out
