Tumbler and line issue

I am struggling with my settings here, I need the white line to not etch but as you can see since the image is so small my K40 takes all the material, is this a settings issue, is my interval too low?

Does the preview look correct?


Yes the preview shows the lines correctly but the laser is still etching over that area

Does the preview look correct when the invert tab is checked? You might need to put a offset line around the project.

Edit. This might not work since it’s an image.

Thank you I tried that but it didn’t work. I modified it in Corel and then converted to a bitmap and will try again tomorrow
