I’ve just started playing around with Inkscape, which allows you to import an image and export it as gcode to then be imported into Sandify. I have yet to figure out how to manipulate ‘tool paths’ in Inkscape so the pumpkins have some errant lines in them, but it’s a good start! Also, this would probably look better with a horizontal wipe applied as the first layer.
