My goal is to load a dxf directly into linuxcnc.


There is an option for this in PathPilot although I have never tried it.

A question.
My goal is to load a dxf directly into linuxcnc.

I see ezdxf can do some work. It can make a dxf file and make a line in the code example.

import ezdxf
dwg = ezdxf.new('R2010')  # create a new DXF R2010 drawing, official DXF version name: 'AC1024'
msp = dwg.modelspace()  # add new entities to the model space
msp.add_line((0, 0), (10, 0))  # add a LINE entity
dwg.saveas('line.dxf')

In g-code the same line looks like :
G01 X0 Y0
G01 X10 Y0

In short, it looks like if you want to load a dxf file into linuxcnc, you must synchronize this to g-code due a text file. Also
inverting a g-code to dxf is possible this way.

Do you know anyone has done this before in python? I saw your name somewhere in the dxf2gcode project.


I wrote a dxf to g code program using golang as the engine and python and glade as the interface. I don't see how it is possible to directly import a dxf file into LinuxCNC because you would need to define the start and end points, speed, feed etc somehow. The program I wrote is rather simple and only starts at the first entity and goes to the last one it finds so the dxf needs to be drawn as the cut path would go.

I'm not a part of the dxf2gcode project.

Hi John,

I am interested in your application and will try is i think sunday. It sounds more promising then the dxf2gcode project to me.
Are you the same person as the JT tutorials?

Aye, I am JT and my web site is gnipsel.com and the name comes from a movie called No Time for Sargent's. I'm also JT-Shop on the IRC. IIRC you can open the dxf2gcode from Axis and send the result to Axis I don't know about other GUI's.
