How to avoid the laser cutting through between shapes?

[sdrgewgrw]

I’m just staring with LightBurn and laser cutting/engraving. When I try to cut a circle with a few shapes inside, the laser also cut between the shapes. I searched where to set the min power option but couldn’t find it, apparently that option is not available on LightBurn 1.2.04, so I don’t know hot to solve the problem.

The image bellow shows in green the two lines that are supposed to be skipped, but they are also cut.

Have you tried $32=1 in the console window.

Laser not turning off between cuts? (burning during travel moves)

If you have a GRBL device, and your laser is still on when moving between shapes, like this: [image] It most likely means you are using GRBL 1.1f or later, but do not have the controller in Laser Mode. Fix this by typing $32=1 in the Console window and pressing enter If you have a Ruida or other DSP controller and are seeing this happen, it is most likely a dying high-voltage power supply unit (PSU). The drive circuit that turns the laser power off and on tends to go first, before the part …

Thanks a lot. That solved the issue.

Hey @Mooseuk, do you know why the power in Laser mode might be much lower. After I run $32=0 on the console the laser power can be adjusted in the Max Power option of the layer, but it burns between shapes. After I run $32=1 to enable laser mode, the power is too low, and it seems as if the values in the option Max Power are ignored.
