[Chris] likedÂ*Cartesian RepRap idea so much that he decided toÂ*design hisÂ*master’s diplomaÂ*project around it. Though it usesÂ*most of the same parts as the RepRap (even the PCBs), [Chris] has adapted it so it does milling rather than 3D printing.Â* Most of the parts (such as the stepper motors) were harvested from old inkjet printers and typewriters. The thee-axis CNC machine can already etch and carve styrofoamÂ*at an impressively highÂ*resolution. To deal with all of the debris that comes with milling, a vacuum attachment (shown attached) was created. [Chris] is considering adapting it so it can workÂ*with wood and aluminum as well. Best of all, it uses standard G-code files, just like the RepRap.Â*A publication by [Chris] on the project is also available through his website. No plans to release a kit have been announced yet, but we’ll wait and see. If any commenter knows of an open source CNC milling machine available as a kit, feel free to postÂ*a link to itÂ*below.
