Hello. I'm new to this stuff so bare with me. I am running mach3, but do not have a cad/cam system in mind yet. I've tried lazycam and liked it, but I would like to try a different(Free) software that mach3 will be able to load. I like gsimple and Deskengrave. They both can create the gcode I need, But I can't figure out how to load it in to mach3. Does mach need to be licenced to accept anything but lazycam? I'm so lost. 500 line of gcode is plenty for what I want to do, so I'd like to try anything i can before I spend alot of money. I don't want to lose intrest due to total confusion. Thank You.
