Tool path setup

[justin.bouchardw (Justin Bouchard)]

Is it possible to have the laser follow the design much like a CNC machine would? For instance. For a simple circle, could the path just follow the outline of the circle or does it have to go left and right(or up and down) to make the design? Forgive my ignorance!

[bernd.dk (Bernd)]

in line mode, a laser behaves like a cnc milling machine but without a spindle up and down, (at most machines)

[justin.bouchardw (Justin Bouchard)]

Ah, so there is a way! Thanks. It still shades pretty well? I think this would save a pile of time

[justin.bouchardw (Justin Bouchard)]

Oh I see it now, So for text it wouldnt make the outline of the letters(with line mode) then fill in just the letters without going across the entire text space. Is there a way for it to peform like a cnc would for a pocket for vcarve(without the z axis movement?)

[justin.bouchardw (Justin Bouchard)]

FLOOD FILL! That’ll do it.

[bernd.dk (Bernd)]

I actually think there is someone here in the forum who runs their cnc router with LightBurn and a diode laser mounted.

[LightBurn (Oz)]

Don’t use flood fill unless it’s for something very simple. The paths generated go back and forth a lot, and any backlash in the machine will show as gaps in the result.

The newer “Offset Fill” is likely what you’re looking for, but again, don’t use it for really complex shapes. It’s really expensive to generate the paths, but it follows the shape and works well for frames.

https://lightburnsoftware.github.io/NewDocs/CutSettings-OffsetFill.html

[justin.bouchardw (Justin Bouchard)]

hmmm, I’m trying an offset of the shape(which is the shape of the province of Manitoba). It does two or three rounds okay, then the machine squeaks a bit and then its off a bit. get the Alarm 3 error:
