Hi I'm pretty new to this, but I have successfully made a case for my OX CNC electronics using SketchuCam and UGS. I tried something else today, but I've failed totally. I downloaded an open source dxf file called twodeer.dxf. I imported this into SketchUp and saved it as an skp file. I scaled it down and added the outside cut paths. When saved as gcode file it looks very strange. The 0.0 position is shown in the centre instead of the bottom left, as on my skp file. It also has 2 rather strange circles over the top of the file. What have I done wrong.?
