• run Inkscape
• optionally set the page size to 800x800px, see also Resolution / Page Size
• ideally set the display units to px (otherwise it can be that in Inkscape 1.1 rectangles and circles are scaled wrong)
• draw something
  • path / rectangle / clone primitives are supported
  • linear gradients are supported
  • the color for laser can be taken either from the stroke or fill color, see Export Options

• execute the ILD Render plugin, found here: (ILD Render must be running in the background)
• 

this option describes how much bezier curves get splitted into lines, quasi the roughness of the resulting laser graphics. Lower values = more points / details

this options describes what do do when there is no stroke color set (color is None)

• use fill color ⇒ uses the fill color for the outline
• use custom color ⇒ uses the custom None color
• don't export ⇒ does what it says, don't export the stroke

use this color when stroke color is None is set to use custom color

options for replacing black colored strokes:

• export as black ⇒ export as black, don't replace
• use fill color ⇒ use the fill color as replacement
• use custom color ⇒ use custom None color as replacement

option to replace black colored fills with custom color for Black

use this color as replacement for black fills

• see the result in ILD Render & on the laser
• adjust the settings in ILD Render if necessary

• only paths and rectangles are exported
  • if elements disappear after exporting to ILD Render make sure to convert these with “Object to Path” in Inkscape
  • 

It's possible to make animations using Inkscape.
To do this check in the ILD Render extension in preferences this checkbox:

Using this mode every layer is treated as one frame of the animation.
