Hi, I'm new to Inkscape and I have trying to convert clipart to gcode using "Gcodetools" extensions. my problem is when I covert clip art to the path using Path > trace Bitmap, the output is a thick line and shows two paths(inner and outer). what I want is to covert this clip art to only one path. Please help me.

There´s a "Centerline tracing" feature coming with "Trace Bitmap" what you gonna need to try. I´d expect best results by manually tracing though.
