how to convert AutoCAD file to CNC laser cutting machine?

The recent CNC laser cutting machines supports the following format files: AI,PLT,DXF,DWG

Convert .dwg to .DXF ( CNC Laser Cutting machine recognizes the DXF) for more info look at this web site http://www.pololu.com/docs/0J24/5 Cheers

this is simple1st in autocad selected profile of and create name after autocad file save as dxf then

open dxf file use layer off comand after all extra like dimensions, normal view hide

req only profile next use pedit comand use for join after save & enjoy for cnc

You have to convert autocad file DWG to DXF .

auto cad software file has to be save as dxf format.and many other file formats are available

convert the autocad file to *.dxf

Firstly you need to output a recognised file format from AutoCAD, DXF happens to be the widely used format.
However be for you begin you must have the object/objects to cut out in model space and purely flattened and single lined 2D shapes.
For this you may need to use the (Overkill) and (Flatten) Command in AutoCAD.
If not already loaded load using the (appload) command.
Locate the relevant AutoCAD lisp files and load them.
Now you will need to import the dxf file into a software such as Rhino or similar programme.
Your laser cutting machine may require the geometry from Rhino or similar programme to convert the data to lines and arcs, depending on the age and sophistication of the machine and installed software being used.
It may be just a case of importing the dxf file direct into the Laser machine, which will then convert the dxf file into lines and arcs as required.

wen you have a special machine is easy just by network but wen you didn't have you need a program for transfer AutoCAD to CNC program like surf-cam or MTS

To convert auto cad file into CNC Laser cutting machine you should use a nesting software like MOST 2D (Material optimization software technology). You can use .dxf file in it for making programme of cnc laser cutting. But there are also many other software in market like AP 100 , Metalix etc.
