I reported some issue on my NEJE Master 2 (20W), when I tried to print somewhere in paper, the shapes are not finnished, it looks like that laser power goes down before finnish the engraving,

Other settings based on this : https://www.northlakeswoodwork.com/blog/2020/7/5/affordable-laser-engraving-lightburn-setup-for-neje-master-2
This issue is common to diff. speed settings (Tested: 10/15/20mm/s / 60/70/80%)
Do You know what can be solved this issue ? Some settings in lightburn ?
You have focus, mechanical and electronic issues, by the looks.
Start with the mechanical - get it running smoothly and reliably. all mounts and screws firm. then check all your electronic connections. You can put a dab of hot glue or silicon on the connectors to firm them up.
Then, when it’s moving smoothly and reliably, get the focus right.
OK thanks, I will doublecheck.
It looks like that I have simillar issue as described there (Ortur LM2 20W Skipping Line Sections) .On dark material burning good.
So, the issue was a focus mainly.
