About Z lift up

Hi gents

I’m using lightburn with a 7W diode to cut rc model parts; now I want to replace the diode head with a self built “head”: it’s basically a needle going up&down really fast inside a guide with the purpose of cutting soft materials like depron, polystirene, etc.
I’m using arduino with GRBL 1.1.
My point is:
how can I instruct Lightburn to lift Z instead of turning off the laser when traveling to other shapes?
It’s in fact what a cnc router normally does.
hope it’s feasible with Lightburn.

Thanks a lot

I just saw few posts asking more or less the same, I have to work with Z offset, isn’t it?
