    DIY CNC Router

    Hi,

    I build my own CNC Router for modell building.
    You can see pictues and videos on http://www.tron-cnc.de (switch to english on the top right).

    The router is quite cheap to build and is perfect for plywood and balsa and CFK.

    You can buy a cheap plan as well (see onlineshop on the page).

    RE: DIY CNC Router

    Looks really nice. Is there a reason you use 2 stepper (or are they servo?) motors for the x axis? Could you not belt drive one screw from the other?

    RE: DIY CNC Router

    There are two Stepper motors connected with a belt.
    This was choosen to synchronize both motors and avoid step losses.

    Might also work with a single stepper, if this is strong enough

    Machine works fine, see videos on my page.

    RE: DIY CNC Router

    I have also made a cnc router for model building. Made it up as I went along. Uses a single acme thread under the table for the X-axis. Works fine on Balsa and ply but not quite stable enough for Aluminium. The router is actually just a Dremel.

    RE: DIY CNC Router

    I have a little question. I am in Victoria Australia, would there be any interest to make parts for anybody? I built it as a project for the hell of it but would be willing to make parts for cost of materials and a bit of time. This is at present only getting interest. Thanks

    RE: DIY CNC Router

    There was a book put out and available via the Nuts and Volts magazine for building such a set up. It gave late 1990's specifications on how to build it and used a Dremel for the cutter. KCam software to drive it, and hold to build your own computer boards to control the stepper motors. Said total cost was to be less than $1000, and it could be even lower today.

    RE: DIY CNC Router

    I am a member of another forum which has many of these homebuilt machines, they are rather easily built and relatively cheap.

    Jens,
    What software did you use to design Tron.

    RE: DIY CNC Router

    I know in a Nuts and Volts Magazine article there was a section on how to make a simple CNC milling machine that was kindof similar to what you have made. It looks like a nice money and time saver.

    RE: DIY CNC Router

    Roger,
    If the plans are in DXF format in your CAD program, you need a program to convert the DXF file to G Code. You then need a program to run the G Code file, which runs your CNC Machine.
    Check out http://www.machsupport.com
    They sell a program called LazyCam for creating the G Code and Mach 3 for running your CNC Machine.
    LazyCam is still in Beta mode, but it works OK for making airplane parts. If you want a G Code program with all the bells and whistles, look into SheetCam.

    If the plans are in Jpeg or Bitmap format, you need to clean them up using MS Paint, then run them through a Raster to Vector program which will save the drawing in a DXF format for your CAD program. There is a freeware program called WinTopo to do the Raster to Vector step.

    Once you run the drawing through the Raster to Vector program, you will need to open the saved DXF file in your CAD program and scale it to the size you want. You will also need to clean it up, usually by overdrawing the part. The G Code program needs the DXF file to be clean with all the lines connected in order to create an accurate G Code file.
    It is a bit time comsuming, but once you have the G Code created you can make as many parts as you want, all the same.

    I'm in the process of scanning, cleaning up, and creating G Code files of a Nick Ziroli 101" B-25 Mitchell plan. I've been at it for a few weeks now, but I'm getting close to cutting my kit for this winter's build.

    Good Luck.
    Mike
