Cut out lettering without losing unconnected pieces

Apologies in advance if this is very noob-like, I’m new to laser, and coming from additive manufacturing, so my brain is currently running inverted.

I’m trying to cut text out, but in the case of letters like ‘o’, if I just do a straightforward cutline, the middle of the letter drops out, which isn’t what I’m going for.

Other than manually editing the vector paths for affected letters to create bridges that will retain the blob in the middle (shown in the below screenshot), is there a more ‘native’ way of doing this? I looked at tabs, but skipping parts of the line doesn’t’ do the trick here.

I’m unclear what your desired end result is- but Lightburn natively support “Tabs” in the left tool bar.

In the layer editing window switch Tabs on, and set how wide you want the tabs to be, and you can also set a partial burns that would continue a line across where it would’ve cut. You will need to do some testing.

You can manually set tabs where you want, so don’t turn on automatic tabs. Just double-click on where you want a tab.

That’s how to do it. The only other option that I’m aware of is to use a “stencil” font. That would have the bridges built into the font natively.

The fastest way that I have found to create the bridges manually is to convert the text to a path, draw a rectangle the width of the bridge by longer than needed, place it across the top and bottom of the “hole” and use the Boolean tools to cut the letter. The text will no longer be editable, so be sure it is what you want before converting to path.

Thanks Patrick, after the initial post I added a screenshot which shows the desired end result - as far as I can tell, tabs can’t achieve this.
