I am hours old newbie here. Trying Lightburn on a chinese grbl w/ 7w laser.
I created a text logo. Set Cut to LINE (outline), set power to 100%, but it does NOT turn the laser down or off between traces of each letter. so they are connected by laser burns. Everything else seems to be set up well, accelerations, speeds, etc.
the Laser is capable of M4 variable power and my MIN POWER setting is missing from the Line Cut settings (understood missing for GRBL). but between letters? I did a outline image of a cartoon and it did not connect all the individual cuts.
