Grayscale images

[Aypac]

In #3 @popeye70 asked:

Hi all,
can this tool generate GCODE from grayscale GIF image, or maybe only from bitmap traces?
I'm trying it on Inkscape 0,92: no error emessages, but it only save header and footer G commands.

My reply:
As far as I know, this addon can only do vector graphics.

Also note, that GCODE is in general not very suitable for grayscale stuff.
Especially bitmaps (each pixel would require two lines of gcode, which would mean GB of GCODE and probably really bad results).
For grayscale line figures (i.e. a vector graphic with different laser power levels); What you can do is to use different colors for different power levels, convert each separately into gcode (and select a different power value) and then run them one after the other or combine them.

You might however try this tricky solution, which has its github repo here.
Or give laser GRBL a shot.

Thank you so much Aypac.
I'm already on Raster to Laser GCODE Generator plugin, and i can confirm that it works with grayscale GIFs.
But the BASTL plugin has more options to set, so i would have loved to try it
