I made some files in Inkscape. Wanted to cut them on the Thunder. Inkscape has problems with DXF export (introduces stray lines in DXF), so the best approach I see is to import the SVG into Adobe Illustrator and save as an AI file, since Inkscape does not have a native AI Save-As option.
This works, but when imported, the size of the image expands: a 4" wide drawing in SVG format becomes 5" wide when saved as an AI and cut on the laser.
I worked around the problem by simply rescaling the image by 80% in AI before saving, but I am wondering: is there a setting I missed? Why are the images expanded by 25% when imported? Expansion seems to be =25%, not about 25%.
