Am wanting to engrave some text amongst other tasks and am unsure on how to set up Mach 3 (demo) to allow me during the program run after the first cut to lift the z axis before moving (jogging) to another part of the work and then dropping again to allow further cuts. I presume you can set this as opposed to manually editing the g code. At present my z axis stays at the same height throughout the whole program (jogging included). My file imports are dxf. Any advice?
