Hi Martin,
In Mach3 click the 'File' tab on the menu bar, then in the list that drops down select the 'Lazy Cam' option. When Lazy Cam loads click 'File' and then click 'Open Vector File' to import the .dxf file, and you will be able to work on the toolpaths prior to saving the file as a g-code file to use as a program. Hope this helps you.
