Solidworks G-Code

[w i l l]

How do I go about producing G-code from a Solidworks 3D model? Do I need to import the model into software such as Mastercam?

Thanks.

You need to bring your model into a CAM package. Mastercam should work. You'll need to play around a bit to see which format works best (ie. stl, dwg, igus etc).

If you haven't bought Mastercam yet, I'd suggest looking at some more "user friendly" options (i.e. Onecnc or MeshCam).

ok, thanks very much. So mastercam isn't that user friendly then? Do you know if I can import a 3d model into Kcam?

Mastercam is a very powerful program, much like Autocad is in the CAD world. However, its also very non-friendly. Its like the difference between windows and DOS. A co-worker tried to learn it and eventually abandoned it for something friendlier.

From their website, it seems that Kcam accepts DXF files (.DXF), HPGL files (.PLT) and Excellon ASCII drill files (.NC).

I just checked and I don't see these as options for Solidworks to save as. This could be a problem unless someone else can see a work-around.

I would skip Kcam and keep looking for an alternative with a wider range of file imports.

Does mastercam/Onecnc or MeshCam use the printer port as a I/O and can you configure the pins? If so I can operate the router from these types of software.

Oh man, Will, you have got some learning ahead of you

Controller software runs your machine. Cadcam software is used to create machine code to feed into your controller software, which them makes your part.

Oh man, HuFlungDung, I know.

I'm just trying to find out if my router can operate from mastercam/Onecnc or MeshCam. The manufacturer recommends kcam, but I can't import a 3D Solidworks model into this.

I asked the manufacturer and he told me this, "If mastercam uses the printer port as a I/O and you can configure the pins then it should work fine.
If not then you can probably export the gcode it creates and load it into Kcam".

Hence my question.

I'm assuming then that means configuring the pins of the controller and mastercam etc should use the printer port on the computer.

I'd stay away from KCAM, especially if you want to do 3D work. Download and try Mach3 to run your machine, and use MeshCAM to create the g-code.

CAM software that creates g-code can not run your machine.

ok, I haven't actually got a machine, I'm just enquiring. The machine I'm referring to is the one advertised on your site from cncdudez.com.

I think this is key to avoiding confusion. You actually need two seperate pieces of software.

1-CAM software that will import your 3d file and convert it to toolpaths, and eventually g-code.

2-Control software that will read your g-code and control your motors during machining (this is where ports and pins become important).

Will,

I would talk to CNCDUDEZ and see if MACH 3 software will control their machines. KCAM is not worth the hassle.

Surfcam, Surfcam, Surfcam. You can't go wrong but it costs big dollars to do surfacing. If you are doing 2-d then it is not so bad. If the part is not complicated you should program it by writing the code yourself. Surfcam, Mastercam and the other CAMs are not efficient at programming simple parts. I can go to machine and knock out code for holes, keyways, bolt circles and the like faster than I can make all of the tool selections and geometery slections in cam packages. I am proficient with Surfcam and have tried Mastercam along with Bobcrap (Bobcad).
