It takes a long toolchain to take the garage-machinist-to-be through all the hoops needed to start cranking out parts. From the choice of CAD software to the CAM tools that turn 3D models into gcode, to the gcode interpretters that chew up this source code and spit out step and direction pulses to turn the cranks of a cnc mill, there’s a multitude of open-and-closed source tools to choose from and even an opportunity to develop some of our own. That’s exactly what [Nick] and the folks over on the cnc-club forums did; they’ve written their own CAM tool that enables the end user to design a procedure of cuts and toolpaths that can export to gcode compatible with LinuxCNC.
Their tool, dubbed “LinuxCNC-features”, embeds a LinuxCNC-compatible graphical gcode programming interface directly into the LinuxCNC native user interface. Creating a part is a matter of defining a list of sequential cuts along programmable toolpaths. These sequential cuts are treatments like drilled holes, square pockets, bolt holes, and lines. The native embedding enables the machinist to preview each of the 3D toolpaths in LinuxCNC’s live view, giving him-or-her a quick-and-dirty check to make sure that their gcode performs as expected before running it. [Nick] has a couple of videos to get you up-and running on either your mill or lathe.
LinuxCNC-features has been out in the wild for almost two years now, but if you’re looking to get started cranking out parts in the garage, look no further for a CAM tool that can quickly generate gcode for simple projects. In case you’re not familiar with LinuxCNC, it’s one of the most mature open-source gcode interpreters designed to turn your PC into a CNC controller, and it’s the brains behind some outstanding DIY CNC machines like this plasma cutter.
