  • Free CNC software

    Found this:

    GNU Computer Aided Manufacturing

    GCAM is the GNU Computer Aided Manufacturing open source package. It currently supports any 3-Axis Computer Numerically Controlled (CNC) mill such as the Taig or Sherline. GCAM consists of a simple interface for making bolt holes, drill holes, and sketches, which after extruded, provide the cutting paths for the selected end mill. GCAM also supports RS274X (Gerber) and Excellon drill files for circuit board milling. Once a design is complete one can export the corresponding G-Code to the appropriate CNC driver of choice such as TurboCNC for DOS or EMC for Linux. GCAM recently entered a stable release mode so please use the Discussion Forum to post any questions and concerns. GCAM is written entirely in C and consists of about 16k lines of code. The GCAM source code can be downloaded from the Files page. Please post all feature requests under Bugzilla.

      Steve,
      Yes this program is well worth a mention as it's a work in progress. The forum reflects the amount of work that has gone into this.

      I recently met Andy Payne, owner and head programmer of Cambam at a recent show.

      His idea is to supply a free program for all to use and a paid upgrade to a professional version later.

        It looks like it's a quick-and-dirty program to generate G-Code from a simple sketch interface.

            I met Andy Payne from Cam Bam at the Austin Maker Faire and was very impressed with his software. The documentation was good and he is haveing fun with his software. If you have a small cnc it is worth checking out.

              It appears to do a lot of the things that I want to do that really don't require a CAD design.

                OOPS! I initially quoted the wrong post.

                  While AutoCAD is by far the most popular professional CAD program, it is by no means the only or even the best. I know engineers at the state department of transportation who would scream bloody murder if they had to switch to AutoCAD from their present multi-kilobuck per seat per year system.

                  I've heard there are other higher-end systems the guys in the aircraft business prefer too. . .

                    DXF doesn't mean AutoCAD anymore it's become the defactor CAD interchange format. The program that Evan posted can't import any CAD format. It has a sketch interface, like Microsoft Paint, and generates G-Code from the sketch.

                    CamBam, that Steve posted, imports DXF files, so you can generate a model with AutoCAD, TurboCAD, Alibre, whatever, and generate G-Code for MACH 3.

                      Why do these these Wiki pages give me the screaming hab-dabs, that full of irrelevant information you can't find fück all.

                      Is it me or do they remind anyone else of VFD manuals

                        He's a graduate student writing Gcam for fun, so I wouldn't expect much in the way of documentation

                        Wiki pages have gotten trendy -- there are dorks where I work (microprocessor designers) who insist on publishing documentation to Wiki pages, but they also write Blogs that no one reads

                        Cool trick on the umlaut 'u' John!

                          I really hate them, the idea of documentation is to be helpful, at one time they were called help files.
                          You could even print them out.

                          Now we have these Wiki's with pages, sub pargraphs, tunnels and whatever nested 17,876 deep [ approx] and no way of printing these out unless you are totally anally retentive.

                          Yes definitly subject matter for a VFD manual...................
