The outline button

Good morning group.

I am trying to get the hang of Gsender and lightburn together. I am not doing to bad but I am curious on how I can use the outline button to see exactly where my project is going to engrave on myt material. When I hit my outline button it seems to run all my toolpath lines and not exactly where on my workpiece it is going to engrave. if anyone has suggestions I am open.
Thank you.

Hi Eric,

If I need to see if my etch is lining out with carvings, I acualy import -what I call- a laser calibration toolpath out of vectric.

Vectric has a great color trace function. I replace the background in a photo with a single color not present in the object that I want to laser, and use that to trace the outline into a single vector.


I generate an on-vector profile toolpath with a single pass out of the vector and export it as an .nc file. When importet in lightburn, I correct the paths into its original size and place it xy0. If it has an offset to xy0, I make sure I include an encompassing rectangle or square into the calibration toolpath that fits the outline, and is dead centre the xy0 coordinates.

After all this I convert the imported lines into a bitmap and trace that bitmap into vectors. Delete the inner vector and generate a line toolpath at full speed and 1% power.

It’s a bit o’ work, but that outline will follow the excact laser-etch, providing you use the outline vector to mask off to the original picture.

If I could somehow use the g-sender outline function, I would. I however don’t see how.

If you are etching a complete picture and want to outline that, just create an outline around the picture in lightburn with the same dimentions, and create a fast1% toolpath for that vector.

Hope this makes sense somehow?

thank you very much I appreciate the response.
