This may well be an operator problem 😉 If I import a shape in to Luban from an Jpg file and tell it to cut using 2 passes it will make 4 passes. If I tell it 1 pass then it makes 2 passes. This seems to only be true if I import a Jpg image. If I create the shape in Luban then 1 pass results in 1 pass and likewise requesting 2 passes results in 2 passes. Any ideas on how to correct this? Thanks! ---

It’s cutting the inside and the outside of the shape/line. Use inkscape to convert it to an svg. -S ---

Is there a setting to prevent Luban from following both the inside and outside of a line? If I import my Jpg in to Inkscape and then save it as Svg will that cure this issue? Sorry I am new to this hobby. ---

No matter how thin my lines are in my JPG file, Snapmaker makes two passes with the second being off my line slightly. Is there a way to get “On The Path” to simply make one pass down the center of the line? I am using Vector for my layout as I need to be able to see the grid markings under my JPG. This is because I have to scale it to a particular size. Any ideas would be appreciated. Thanks! ---

Hi, a bit late to reply but. If you use bitmap lines, then you will have both side used by the laser. So, if you dont have a svg file, you can fill the drawing. What I mean is, if you have a square = 2 lines, if you fill the square = 1 line ![avirer](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/d/3/d396e6682b4e5f52b9010d1f5e5cfa7831d2d18d.png)
